Glass fiber increases the wear and creep resistance of PTFE. It is the most common PTFE filler. Glass fiber-filled PTFE materials can be used in oxidizing environments, but be aware that glass fiber reacts with HF and strong bases.
Glass fiber-filled PTFE materials have a slightly higher coefficient of friction but better extrusion resistance than Glass fiber/Moly filled PTFE materials. They are typically used in seal components for dynamic applications. They also prefer a lubricated environment and are used to seal against steel, stainless steel, and chromium-plated surfaces.
PBY Material Codes:
PB10302G - 15% Glass Fiber Filled PTFE
PB10305T - 25% Glass Fiber Filled PTFE
Increases wear and creep resistance
Chemically Inert (Exceptions in HF and Strong Bases)
Performs well in oxidizing environments
PB10302G meets ASTM D4547 Type I Grade I requirements.
PB10305T meets ASTM D4745 Type I Grade 2 and AMS 3678/4 requirements
