Glass Fiber-Filled PTFE
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.
