Jan 8, 2025 · Glass-filled PTFE is a composite material in which glass fiber (typically 15% to 25%) is added to PTFE to enhance its mechanical strength, wear resistance, and dimensional stability while still retaining PTFE’s excellent chemical and thermal properties.

PTFE fillers are additives used to modify the properties of PTFE-based materials. These fillers can improve mechanical strength, electrical conductivity, wear resistance, and other characteristics of PTFE, and enhance its performance in specific applications. How to Choose The Right PTFE Fillers for Your Application?

PTFE with 25% glass fibers for increased stability is supplied in sheets, rods & tubes. Available in Standard 25% Glass Filler. Also available in 15%, 20%, and other custom blends.

Buy glass-filled PTFE plastic materials from Curbell Plastics. Shop a variety of high-quality PTFE sheets and rods that can be cut to size for your next project.

May 20, 2023 · Glass Filled PTFE (also call glass fiber filled PTFE, glass reinforced PTFE) is manufactured from a base of virgin PTFE or midified PTFE which is strengthened by the addition of glass fiber.

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/Moly-Filled PTFE Moly increases the surface hardness of PTFE while decreasing friction. It is commonly added in small amounts and combined with other fillers such as glass.

What is Glass-Filled PTFE? Glass-filled PTFE is a variant of polytetrafluoroethylene (PTFE) reinforced with glass fibers, typically ranging from 5% to 25%. This combination significantly enhances the mechanical properties of PTFE, such as wear resistance, dimensional stability, and compression strength, without compromising its chemical or ...
