PTFE GlasMoS2 grey 58 Shore D Compound
Glass Fiber + MoS₂ Filled PTFE for Dimensionally Stable, Low-Friction Sealing Applications
PTFE GlasMoS₂ (58 Shore D, grey) is a dual-filled PTFE compound combining glass fibers for structural reinforcement and molybdenum disulfide (MoS₂) for improved self-lubrication. This synergistic blend enhances wear resistance, compressive strength, and low-friction performance, making it ideal for non-lubricated, high-load, and precision sealing applications.
The material offers dimensional stability, chemical resistance, and low deformation under thermal and mechanical stress, especially in hydraulic and pneumatic systems.
