Application

PTFE Compounds

Supernol® Aromatic Polyester Powders are a key component in extending the life of parts and components made from PTFE compounds.

When used as a reinforcing filler in PTFE, Supernol® provides:

• good compression, creep resistance, dimensional stability and load-bearing capacity
• excellent wear resistance (5,000 times lower wear than PTFE), without increasing the coefficient of friction
• low abrasiveness: Supernol® / PTFE compounds will not damage soft mating surfaces such as aluminum, stainless steel, and brass

The unique combination of wear resistance, low coefficient of friction, and low abrasiveness makes Supernol® an ideal reinforcing filler for PTFE.

Supernol® powders are used as the sole reinforcing filler in PTFE, typically in the range of 10 to 30 weight %, or in combination with other fillers such as graphite or carbon fiber to cover a wide range of applications as shown in the following table.

Other Applications

Reinforcing Fillers for Fluropolymer and Engineered Polymers

Supernol® can be used as reinforcing fillers in Thermoplastic Fluoropolymers (ETFE, FEP, PFA, etc) and other engineered polymers such as Liquid Crystal Polymers (LCP), Polyetheretherketone (PEEK),  PSU, PESU, PES, PAI and polyimide, etc., providing similar benefits with drastically reduced wear, friction and abrasion.

Supernol® High Performance Molding Compounds

Supernol® powders can be hot compressed or direct molded to produce high performance, intricate components.

Thermal Spray Powders

Supernol® powders can be utilized to produce thermal spray abradable materials to minimize the gap between compressor blade tips and rotor paths to improve fuel efficiency.
