Types of Plastics used in the Semiconductor Industry

August 23, 2022  |  , , , ,

Precision and purity are key in the semiconductor industry.  Plastics help maintain high standards of precision and purity during semiconductor production, ensuring that less time and resources are wasted and that electronics function properly.

Since plastics are typically insulators, they may seem an unlikely material for use in semiconductor / electrical applications. However, in recent years, the composition of some plastic materials has been adapted to make these plastic materials behave as conductors or semi-conductors as opposed to insulators.

The semiconductor industry requires components that are manufactured from materials having a combination of heat resistance, conductivity, insulating, and shielding properties. All these properties are exhibited by high performance plastics. They are ideal materials with which to produce end products, as well as parts in the processing equipment used to manufacture semiconductors.

High performance plastics such as Fluorinated Ethylene Propylene (FEP), Polyether Ether Ketone (PEEK), and Polytetrafluoroethylene (PTFE), are characterized by their exceptional properties in different areas. High performance plastics are largely used where highest demands are placed on thermal or chemical resistance or product mechanics.

  • FEP – Fluorinatedethylenepropylene is a copolymer of hexafluoropropylene and   tetrafluoroetheylene;   boosts chemical resistance and useful low friction properties, and is  easily formable.  FEP is soft, slightly flexible, possesses a lower melting point of 260°C and is highly transparent and resistant to sunlight.  It is vastly superior in some coating applications involving exposure to detergents.

 

  • PEEK – Poly Ether Ketone  is a semicrystalline thermoplastic with exceptional high temperature performance, mechanical strength, and chemical resistance. It is capable of maintaining its stiffness at high temperatures and is suitable for continuous use up to 260°C (480°F). In addition, PEEK does not undergo hydrolysis and can be used for significantly long periods of time in areas where steam or water is common.

 

  • PTFE – Polytetrafluoroethylene is a tough, flexible, non-resilient material of average tensile strength with great thermal properties and excellent resistance to chemicals and passage of electric current. The coefficient of friction is unusually low and believed to be lower than any other solids. PTFE is an outstanding insulator over a wide range of temperatures and frequency.

Injection Molded PFA for Semicon Meets F-57 Requirements

August 2, 2022  |  , , ,

At Performance Plastics, we hold the quality of our products to the highest standards. We know that quality is critical for our customers, so we go above and beyond to make sure our customers products are no less than ideal.

Manufacturing quality products is key to maintaining long term relationships with our customers. We take the time after injection molding a product to test the quality and to quantify compliance standards. This extra time assures that we are meeting all the specifications of our customers’ products.  To this end, we maintain SEMI F57 compliance for our customers PFA (Perfluoroalkoxy) and PTFE (polytetrafluoroethylene) injection molded products.

SEMI F57 compliance is a specification for polymer materials and components used in ultrapure water and liquid chemical distribution systems. The SEMI F57 standard requires fluid-component manufacturers to follow best practices in material science and not contaminate UHP processes with extractable ions, metallics or total organic carbon (TOC). The standard also covers surface roughness, particle contribution, metallic contamination, and reliability testing.

SEMI F57 Standards ensure compliance as they identify permissible limits for seven different aqueous leachable anions: bromide, chloride, fluoride, nitrate, nitrite, phosphate and sulfate.  Additionally, the standards measure for elevated levels of total organic carbon (TOC) which can have negative effect on silicon oxidation.

In order to ensure that we maintain SEMI F57 compliance, we have added new, additional quality testing steps. The steps occur during the molding, cleaning, drying and packaging processes. These quality tests are crucial – they certify that each product injection molded by Performance Plastics follows the SEMI F57 standards and will not contaminate ultrapure water and liquid chemical distribution systems.

For more information on how Performance Plastics can help your injection molded PFA or PTFE product achieve SEMI F57 compliance, contact Rich Reed our Vice President of Sales and Marketing, at (513) 321-8404 or [email protected].

High Performance Polymers – A Great Alternative for Medical Devices

June 9, 2022  |  , , ,

Diabetes care has seen several innovations through the years. One of the most important developments is the insulin pump, which for many patients provides an option to the traditional needle and syringe approach to insulin injections. Insulin pumps are small, computerized devices that are about the size of a small cell phone.  Insulin pumps deliver doses of insulin, the hormone that regulates blood sugar, on a pre-programmed schedule.

High performance polymers have enabled medical device manufacturers to go beyond the functionality of ordinary plastic materials to develop innovative devices for treating diabetic patients.  Resins such as FEP and PFA fluoropolymers are chemically resistant resin with outstanding properties and are currently used in numerous healthcare applications. Physical properties of resins such as high tensile strength, dimensional stability, excellent friction and wear characteristics and the ability to replicate fine features are important advantages as parts become smaller and thinner.

In developing new and advanced insulin delivery devices, resins offer unique advantages and have expanded the possibilities for innovative design and manufacturing. Medical grade fluoropolymers, such as FEP and PFA allow for the miniaturization of device components without the constraints of glass or ordinary plastic materials. With these capabilities, designers can now expand design performance and possibilities. Fine detail replication resulting from the material’s high flow and excellent dimensional stability properties position resins as an excellent material for lightweight and compact precision delivery devices.

Device components such as insulin storage require the use of a proven polymer materials. In addition to compatibility with insulin, purity and very low levels of leaching, resins provide excellent moisture barriers and extremely low water absorption, both necessary properties for optimal long-term drug container storage. These resins are also FDA approved and are compatible with all conventional sterilization methods from gamma to steam.

In future insulin delivery systems, the use of FEP and PFA resin components for various parts of the device will continue to rise. With the advantages engineering polymers offer for design innovation and performance, resins will continue to be the material of choice for delivery applications.

At Performance Plastics, we are experts in injection molding, specializing in high performance plastics. Our proprietary tool design software, processes and equipment enable us to injection mold components having complex geometries made from challenging ultra, high-performance thermoplastic materials, and reinforced compounds.

Fluoropolymers Are A Great Choice For Parts That Must Perform In Unique Conditions

May 19, 2022  |  , , ,

When you need parts that can withstand extreme operating conditions, fluoropolymers may fit the bill. Parts like roofing membranes, fuel tubes, biomedical devices, and wires are all common applications of fluoropolymers.

FEP Fluoropolymer:

Fluorinated ethylene propylene (FEP resin) is a melt-processable fluoropolymer. FEP has low gas and permeability properties, can be extruded in long continuous lengths, and possesses excellent UV transmission rating. FEP is also suitable for use in a biomedical setting and is gamma sterilizable.

All of these attributes make FEP an ideal fluoropolymer for a diverse range of applications from environmental monitoring equipment to medical devices and electronics. Because it is a thermoplastic, FEP is also easily heat-formed, tipped, tapered, flared, and flanged.

PFA Fluoropolymer:

Perfluoroalkoxy (PFA resin) is a melt-processable fluoropolymer that combines many of the best traits of PTFE and FEP. At 500 °F (260 °C), PFA has a higher service temperature than FEP and maintains its mechanical integrity in extreme temperatures even when exposed to caustic chemicals. PFA has greater tensile strength than PTFE and a smoother surface finish than both PTFE and FEP.

PFA’s is a top choice in semiconductor, chemical, oil and gas, aerospace, automotive, pharmaceutical, and medical industries. This fluoropolymer has excellent lubricity, clarity, flexibility, and chemical resistance, making it a versatile choice.

FEP vs PFA Fluoropolymers

FEP and PFA are injection moldable, highly inert, compatible with most organic compounds, have good barrier properties and high continuous use temperatures. They are virtually impervious to chemical, enzyme and microbiological attack and stiffer than PTFE. The non-stick properties of these polymers can also be useful to reduce liquid, gel and powder adhesion. Fluoropolymers in general, have good dielectric properties and are resistant to atmospheric degradation.
While significantly less expensive than PFA, FEP is very difficult to mold due to its low viscosity. However, Performance Plastics has developed proprietary tooling and processes enabling the injection molding of small, thin-walled, complex FEP parts.

• More transparent than PTFE (not injection moldable)

• Better gas and vapor permeability properties than PTFE
• Maximum working temperature 400°F
• Approximately 1/3 the cost of PFA

PFA is significantly easier to mold than FEP, however, it is significantly more expensive.

• Higher continuous service temperature than FEP
• Maximum working temperature 500°F
• Difference in molecular structure gives PFA improved flow, creep resistance and thermal stability.

At Performance Plastics, we are experts in injection molding, specializing in high performance plastics. Our proprietary tool design software, processes and equipment enable us to injection mold components having complex geometries made from challenging ultra, high-performance thermoplastic materials, and reinforced compounds.

Injection Molded PFA in the Lithium Ion Battery

December 17, 2021  |  , , , ,

The Lithium Ion Battery industry has begun using more and more plastic parts in their manufacturing processes. Most batteries intended for light vehicle usage now have 50% more plastic materials than they did even 10 years ago.  Some batteries have entirely plastic formulations ranging from the electrolyte (polymeric electrolytes) to the casing.  This is due to the very low weight of plastics as compared to metals. Plastic incorporation in batteries increases the electrolyte efficiency if used in polymeric electrolytes.

Commercially available lithium-ion batteries also use plastics. Plastic components incorporated in batteries include separators, gaskets, and casing components. Plastics have good shock absorbing characteristics and prevent damage to the basic cell unit from minor accidental shocks. Also, plastics such as Teflon® PFA, Ultem® PEI, and PPSU have high temperature resistance, corrosion resistance, and are electrical insulators so they are excellent at preventing short-circuit and “rapid disassembly.”

There has been a major shift from metal to resins in gasket manufacturing. Gaskets can be made from Ultem®, Ryton PPS and Fluoropolymers (PFA plastic) because of high heat resistance, chemical resistance, and ability to mold thin walls (.012”). Plastic parts may also lower the cost of production of batteries and may eventually replace most metallic components of batteries.

Performance Plastics is highly skilled at designing and molding high performance materials such as FEP/PFA, Ultem®, Torlon®, PEEK, POM, and PPS.  We work with our customers to solve technically challenging problems.   We can propose materials to implement part functionality in the design stage of development. We offer manufacturing solutions such as a clean room, the ability to offer direct gating of fluoropolymers, high volume production, visual inspection and automated facilities.

What is a High Performance Plastic?

November 4, 2021  |  , , ,
Ultem PEI Polyethermide thermoplastic component

Ultem PEI Polyetherimide thermoplastic component

High performance plastics are plastics that meet higher requirements than standard or engineering plastics. Generally, they are used in smaller amounts for critical applications such as aerospace, defense, medical or industrial applications. They represent about 1% of the plastics manufactured worldwide. High performance plastics differ from standard plastics primarily by their higher thermal stability, outstanding chemical resistance, and superior product quality.

There are many names for the term high-performance plastics, such as: high temperature plastics, high performance polymers, high performance thermoplastics or high tech plastics. The term “polymers” is often used instead of “plastics” when referring to a high performance plastic. Performance plastics are often achieved by the addition of stabilizers and reinforcing materials such as glass and carbon fibers to increase the degree of polymerization.

When it comes to thermal stability, high performance plastics generally have an operating temperature over 300ºF. One material, PEEK, can hold a continuous operating temperature of 500ºF, while another called Celazole® PBI has a continuous service capability of 750ºF. High performance plastics won’t deform or degrade in high temperature applications and maintain their superior mechanical properties.

High performance plastics also offer outstanding chemical resistance. PPS, FEP/PFA and PAI are resistant to a broad range of chemicals while Teflon® (PTFE) is almost entirely chemically inert and highly insoluble in most solvents or chemicals.
High performance plastics offer superior product quality in terms of machinability, durability, reusability, and recyclable qualities. They are used in a wide range of multi-use applications and durable applications and are frequently used to replace other materials such as metal, wood, and glass. Nearly all high performance plastics are recyclable.

The superior product quality of high-performance plastics (specifically their high heat resistance and strength/stiffness) can make them difficult to process, often requiring specialized machinery and talent. This, combined with their higher material cost, generally restrict their use to specialized applications. However, their capabilities and outstanding performance make high-performance plastic parts well worth the cost.

Plastic Injection Molding vs 3D Printing

June 3, 2021  |  , , , , , ,

Choosing the best technology for your application

Plastic injection molding and 3D printing are both viable technologies. 3D printing has given engineers the power to create designs and bring them to life in a matter of hours. Injection molding, on the other hand, is the proven technology for complexity, quality, and value. It is used to produce high-volume runs of complex plastic designs quickly and reliably. They are complimentary processes.

The use of 3D printing in innovative and experimental scenarios is a viable technology for its ability to create custom plastic part designs quickly.  The medical industry has embraced the use of the quick-turn technology to create custom items such as prosthetics, dental products, orthopedics, implants and more.  3D printing is the optimal choice during the design process, when low volume and design changes are necessary in refining the design process. However, the 3D process limits your material choices, as all materials are not a fit or even available in a form suitable for 3D printing.

3D printing is best used for:

  • Quick turnaround times
  • Low volume, slower production speeds
  • Parts in the design phase with frequent changes – prototyping, lower product quality
  • Smaller part sizes

Once a design has been finalized, plastic injection molding becomes the optimal process.  Most of today’s plastic parts are manufactured using plastic injection molding – it’s best for producing large quantities quickly and reliably in high volume runs. You have greater material options with plastic injection molding, and you can control material weight, cost, flexibility with endless combinations of materials.  It helps organizations control the cost and integrity of designs with complexities and tight tolerances.

Plastic Injection molding is best used for:

  • High volume
  • Finalized part design
  • Enhanced strength and durability
  • Complex, precision, detailed parts

At Performance Plastics we have been presented with many opportunities that were previously manufactured using 3D printing, only to discover that injection molding was the more appropriate technology.  As experts in FEP, PFA, PAI (Torlon), Ryton PPS, PEEK and Ultem resins we frequently work with mission-critical applications.  We understand that 3D printing can be an essential component of the design process.  If you have a project that requires high volume (5,000+ parts per year), has high-temperature resin requirements, tight tolerance with complex geometries, plastic injection molding is your solution.

If you don’t have a lot of time, need a lot of flexibility, and need a few parts right now, 3D printing may be your choice.  But, if you need to do large, repetitive product runs with complex geometries, tight tolerances, with high quality, consider plastic injection molding.
