FORWA PTFE Sheet
Polytetrafluoroethylene sheet · High-performance engineering plastic sheet · King of Plastics
FORWA · SINCE 1993
Product Introduction
Polytetrafluoroethylene sheet (PTFE sheet) is a high-performance engineering plastic sheet made from Polytetrafluoroethylene resin as the main raw material through processes such as molding and sintering. PTFE is also known as the "King of Plastics" and has excellent chemical stability, high temperature resistance, and a low coefficient of friction. It is an indispensable high-performance material in modern industry.
FORWA PTFE Sheet is strictly controlled in raw material formulation and molding process. The product has uniform density and a flat surface, suitable for industrial scenarios with high precision and cleanliness requirements. The sheet has excellent chemical resistance, wide temperature range applicability, ultra-low coefficient of friction, excellent electrical insulation, and a non-stick surface. It is widely used in chemical, mechanical, electronics and electrical, food and pharmaceutical, aerospace, and other fields.

Core Advantages
Excellent Chemical Resistance
Almost unaffected by any chemicals, resistant to almost all strong acids, strong alkalis, strong oxidants, and organic solvents. Not affected by ultraviolet light or ozone, with stable performance during long-term use.
Wide Temperature Range Applicability
Maintains stable performance from -200℃ ultra-low temperature to +260℃ high temperature. Melting point 327℃, meeting long-term use requirements under extreme working conditions.
Ultra-Low Coefficient of Friction
Coefficient of friction as low as 0.04–0.15, the lowest among all plastics. Excellent self-lubricating performance reduces friction and wear of mechanical moving parts and lowers energy consumption.
Excellent Electrical Insulation
Volume resistivity > 10¹⁸ Ω·cm, dielectric constant 2.1–2.2, dielectric loss 0.0001–0.0005, stable performance at high frequencies, suitable for high-frequency cables and precision electronic equipment.
