Materials used Aircraft Maintenance Scrapper Blades

January 18, 2024  |  , , ,

 

Aircraft Maintenance Professionals are always looking for better and more efficient ways to complete their tasks.  Sometimes, in an effort to complete their tasks faster, they use items that were not designed for use in removal and damage to the underlying surfaces.

While there are currently many scraper blades on the market that are designed for adhesive removal, , not all materials are created equal.  Most of the blades currently on the market are made of three materials:  ABS, Phenolic, and Torlon.

 

ABS

Acrylonitrile Butadiene Styrene is a very tough, very durable thermoplastic used in a wide variety of applications. ABS is a common choice among other plastic production materials because of its durability, structural stability, and good corrosion, impact, chemical, and wear resistance.

ABS plastic is made when acrylonitrile and polystyrene monomers are polymerized with butadiene rubber to create acrylonitrile butadiene styrene (ABS). This blending is typically accomplished using an emulsification process, wherein materials that would otherwise not mix are formulated into a cohesive single product (think milk, where fats, oil, and water do not separate out of solution but exist as a homogenous mixture)

Phenolic

Phenolic is a laminated plastic used in a variety of custom plastic components due to its high strength, resistance to solvents, dielectric strength, and many other features.

Phenolics are manufactured by impregnating layers of material with a phenolic resin, and then applying heat and pressure, which transforms these layers into a solid mass. The result is a thermoset that is dense, dimensionally stable, structurally strong, has low creep, and is an excellent insulator.

Torlon

 

 

Torlon® is a high-strength, high-performance, melt-processable plastic material. It’s ability to perform under severe stress combined with its resistance to elevated temperatures makes it ideal for various applications across many industries.  Torlon (PAI) is recognized as being the highest-performing plastic that is melt-processable.

Polyamide-imides (PAIs) are thermoplastic amorphous polymers prepared by the condensation of an aromatic diamine, such as methylene diamine, and an anhydride, such as trimellitic acid chloride. PAIs have good mechanical, thermal, and chemical resistance, high strength, melt processability, and high heat capacity.

So, ABS is blended thermoplastic, Phenolic is impregnated plastic, and Torlon is a heat-treated, condensed thermoset.  Condensed thermoset materials are stronger, more resilient, and exhibit consistent performance without the risk of damaging the surfaces.

EnduroSharp® Torlon® aircraft maintenance tools were specifically designed by Performance Plastics, the Airforce Research Laboratory (ARL), and the University of Dayton Research Institute at Wright Patterson Air Force Base to safely and efficiently remove adhesives, sealants, and coatings while maintaining an effective edge and not damaging the underlying substrates.

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.
