Peek use in Semi-Conductor Applications – Wafer Manufacturing

February 7, 2023  |  , , ,

 

PEEK is short for polyether ether ketone. These polymers are notable for their phenylene rings and oxygen bridges, which result in resilience, durability, and strength.

Wafer manufacturing is a term used to describe the process of creating chips, otherwise known as integrated circuits, which are used in everyday devices.  You will find chips in everything from cars to military jets.  PEEK is great for semiconductor applications because of its outstanding combination of physical properties.

  • Longer Lifetime – CMP (chemical-mechanical positioning) rings made with PEEK can provide less downtime, and more throughput with up 2x wear resistance compared to other materials.
  • Potential Yield Enhancement – Low particle generation and higher purity, resulting in lower outgassing and extractives that may lead to yield improvements
  • Faster Process – PEEK endures proceseess with up to 260° and harsh chemicals, which allos for faster processing and less cooling time.

Semiconductor equipment manufacturers use PEEK screws and fasteners in wet benches. Chip manufacturers use hydrofluoric acid which is a corrosive chemical that can damage metals. Since PEEK is chemical-resistant, chip manufacturers are utilizing PEEK screws. These screws are used in the production of ICU’s since they are a high-purity material and possess low-outgas properties. PEEK is also used to manufacture manifolds for semiconductor production equipment.

Performance Plastics’ team of experienced engineers possess the expertise to design and manufacture technically challenging projects and offer complex solutions within the semiconductor industry.

Does your part need Flexibility & Strength – Consider Nylon®

January 26, 2023  |  , , ,

Nylon® is a synthetic thermoplastic polyamide that is known for its strength, temperature resilience, and chemical compatibility. It has been proven to be a lightweight, heavy-duty industrial engineering plastic replacement for metals that are resistant to both heat and corrosive chemicals.

Nylon® is a great material for parts that undergo flexure and bending.  With wear resistance far greater than many metals and other thermoplastics and a low coefficient of friction, Nylon® is ideally suited for use in slides, bearings, and other parts that need to stand up to high levels of motion and wear. Performance Plastics offers expertise in developing Nylon® resin formulations and combinations with other polymers such as glass, carbon, and mineral-reinforced versions.  For example, Minlon®, a mineral-reinforced Nylon® provides greater dimensional stability and creep resistance than unreinforced Nylon®, and lower warpage than glass-reinforced Nylon®. As a result, it is popular for use in compressor valves and big industrial parts, as well as in demanding aerospace applications.

Performance Plastics has seen Nylon®’s applications grow to include a range of applications to move water, acids, lubricants, solvents, chemicals, and fuels in automotive, military, and aerospace environments.  Although pump makers traditionally used various metals for pump housings, shaft guides, impellers, seals, bushings, and other elements, the desire to reduce pump weight, material, and processing costs have led many to opt for various Nylon® formulations instead. Performance Plastics can use Nylon® to offer a combination of physical strength, wear resistance, self-lubrication, and high cost-effectiveness.

Choosing the optimal Nylon® resin for an application depends on several factors, including the levels of pressure, temperature, and speed involved. In addition, the abrasiveness of the liquids or slurries involved, the degree of contamination that can be tolerated, and projected uses for the part must also be considered.

Nylon®’s toughness and elongation properties make it suitable for designs that involve snap-fits or press-fits. Injection-molded Nylon® parts from Performance Plastics are well-suited to secondary machining processes such as turning, drilling, tapping, and grinding, as well as ultrasonic insertion, ultrasonic welding, pad printing, and assembly.

What You Don’t Know About FEP/PFA Injection Mold is Costing You Money

December 7, 2022  |  , , ,

A fluoropolymer is one of the growing numbers fluorocarbon-based polymers. They are widely used in healthcare applications due to their biocompatibility, lubricity, sterilizability, chemical inertness, thermal stability, barrier properties, and high purity. However, when compared with other resins, they are significantly more expensive and require special techniques to injection mold due to their shear sensitivity, high melt temperatures, and fluorine outgassing when melted.

Although the best-known fluoropolymer, polytetrafluoroethylene (PTFE or Teflon®), has been on the market since the 1940s, newer resins have been developed to address specific injection molding niches. Perfluoroalkoxy polymer (PFA) and fluorinated ethylene-propylene (FEP plastic) are among the most recent additions to the list of fluoropolymer options.

PFA was developed in order to create a true melt-processable fluoropolymer. It provides the smoothest and least wettable finish of all of the fluoropolymers. Its optical transparency, chemical inertness, and overall flexibility have made it popular for use in lab equipment. It also has superior electrical properties, with dielectric strength that’s three to four times greater than PTFE can offer.

Like PFA, FEP is melt-processable and injection moldable. Its melting point of 260 °C (500 °F) is about 40 degrees lower than PFA’s.  It offers low friction and chemical inertness properties comparable to PTFE’s. However, it is completely transparent. Because FEP is highly resistant to sunlight, it is especially useful for molding parts that are subjected to weathering.

However, not all injection molders are equipped to work with fluoropolymers like PFA and FEP. Performance Plastics LTD. has developed a variety of tools and procedures to address the challenges involved in molding these materials. For example, our solution includes a hot runner system and mold designed to minimize the shear forces inherent in the injection molding process. We use proprietary metallurgy that’s highly resistant to fluorine gas corrosion, which helps extend the working life of the hot runner system, tooling and other components that make contact with the melted resin. We’ve also developed a direct-gating, multi-runner approach to tool design that eliminates the sprue and runner used in traditional injection molding. By eliminating the wasted material associated with the sprue and runner, Performance Plastics has been able to pass along material cost savings of from 20% to 40% by using these expensive resins more economically.

To learn more about how we can cut your resin costs while helping you take advantage of the unique properties PFA and FEP offer, visit our contact page or contact Rich Reed, our vice president of sales and marketing, at (513) 321-8404 or [email protected].

Plastic Injection Molding vs 3D Printing (Part 2)

November 16, 2022  |  , , ,

How to choose the best technology for your project.

 

Plastic injection molding and 3D printing are both viable technologies. 3D printing is an additive printing process that creates objects by building up layers of material, while injection molding uses a mold that is filled with molten materials that cool and harden to produce parts.

The use of 3D printing in innovative and experimental scenarios is a viable technology for its ability to create custom plastic part designs quickly.  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, and 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 optimized many projects that were once manufactured using 3D printing, only to discover that injection molding was the more efficient technology.  As experts in FEP, PFA, PAI (Torlon), PEEK, and Ultem resins we frequently work with mission-critical, time-sensitive applications.  3D printing is an essential component of the design process, but If you have a project that requires high volume (5,000+ parts per year), high-temperature resins, and tight tolerances with complex geometries, plastic injection molding is your solution.

Performance Plastics’ team of experienced engineers possesses the expertise to design and manufacture technically challenging projects and offer complex solutions within harsh application industries.

Fluoropolymers may be the solution to the Medical Glass Shortage

November 10, 2022  |  , , , ,

The shortage of glass has been an ongoing issue. Experts say the price of glass is on the rise as global supply chain issues continue throughout the world.  The glass shortage affects all industries that rely on glass for their containers, but right now, with the convergence of annual flu, the emergence of new COVID variants (Omicron), and the outbreak of Respiratory Syncytial Virus Infection (RSV) in children, the medical field is in dire need of glass for vials.

Silicon, which is one of the materials that is used in glass manufacturing has been in short supply for over a year.  Medical vials are made of Type I borosilicate glass, and this form uses the most silicon. The decreases in the recycling rates during the pandemic, are additionally hurting the production of glass vials.

Fluoropolymers such as FEP, PFA, and PCTFE are great alternative materials for glass. These fluoropolymers are superior to conventional plastics. Their inert, non-reactive, and unmatched durability makes their properties ideal for use in the medical industry. These fluoropolymers are also non-stick, ensuring the product does not adsorb to surfaces. They are also virtually impervious to chemical, enzyme, and microbiological attacks. All the benefits of FEP, PFA, and PCTFE make these fluoropolymers a perfect material to create vials out of, especially since they are injection moldable.

At Performance Plastics, we have extensive experience in injection molding fluoropolymers. We have developed proprietary tooling and processes enabling the injection molding of small, thin-walled, complex parts. Our expertise in fluoropolymers and injection molding can be the solution to the shortage of glass.

PEEK® for Aerospace/Defense Applications

September 26, 2022  |  , ,

PEEK or polyetheretherketone belongs to a family of polymers called polyketones or iPAEKs.  This means that is it built from the following building blocks:

  • ARYL
  • ETHER
  • KETONE

PEEK is one of the highest performing thermoplastics in the world.  Compared to metals, PEEK based materials are very light weight, easily shaped, resistant to corrosion and have considerably higher specific strength (strength per unit weight).

PEEK is optimal for aerospace applications because although it is a thermoplastic, it boasts heat resistance, little to no reaction against harmful chemicals and radiation, and comparable tensile and load strength to that of titanium and steel while being many times lighter.

PEEK® does not offer merely two or three properties that mark it as the polymer of choice for aerospace/defense; it has a whole variety of them.  They include:

  • High heat resistance

Tests have shown that PEEK polymer has a continuous use temperature of 260°C (500°F). This can make it suitable for use in a wide range of thermally aggressive environments.  PEEK tolerates friction and resists wear in dynamic applications like thrust washers and seal rings.

  • Chemically unreactive

PEEK resists the damage that can be inflicted in chemically aggressive operational environments. It can resist jet fuel, hydraulic fluids, de-icers and insecticides used in the aerospace industry.  This holds true over wide ranges of pressure, temperature, and time.

  • Mechanically strong

PEEK offers excellent strength and stiffness over a wide temperature range.  PEEK-based composites have specific strength many times that of metals and alloys.  “Creep” refers to a material becoming permanently deformed over an extended period when under constant applied stress. “Fatigue” refers to the brittle failure of a material under a repeated cyclic loading.  PEEK has both high creep and fatigue resistance thanks to its semi-crystalline structure and has been shown to be more durable than many other polymers and some metals over a long and useful lifetime.

  • Difficult to ignite or burn

PEEK has excellent flammability performance.  It resists combustion up to almost 600°C.  When it can be made to burn at very high temperatures, it will not support combustion and it emits little smoke. This is one reason why PEEK is widely used in commercial aircraft.

Aerospace/defense part manufacturers now use PEEK as a way to improve the weight and durability of their parts.  PEEK is a standard high-performance plastics in the aerospace/defense industry applications.

Performance Plastics’ team of experienced engineers possess the expertise to design and manufacture technically challenging projects and offer complex solutions within the aerospace/defense industries.
