PTFE Sheet
PTFE Sheet is a solid material made from polytetrafluoroethylene, valued for its smooth surface, chemical stability, and resistance to extreme temperatures. It is commonly used as a lining, sealing, or anti-stick material in chemical equipment, semiconductor systems, and industrial machinery. The product is available in three forms: molded sheets for machining and heavy-duty applications, skived sheets for thin and flexible uses, and sodium-treated sheets for bonding to other materials.
Key Features
Wide Operating Temperature Range
Performs reliably from -180ºC to +260ºC, maintaining flexibility at low temperatures and strength at high temperatures.
Chemical and Corrosion Resistance
Highly resistant to acids, alkalis, and solvents, making it suitable for aggressive chemical and process environments.
Low Friction and Non-Stick Surface
Naturally self-lubricating, it reduces friction and prevents surface adhesion, making it ideal for low-friction or anti-stick applications.
Non-Flammable and Oxidation-Resistant
Retains structural integrity in high-temperature or oxidative conditions without degrading or burning.
Electrical Insulation
Excellent electrical insulation with high dielectric strength, suitable for electronic and semiconductor use.
Product Types
Molded Sheet
Compression-molded and sintered for rigidity and density; used for machining into gaskets, seals, and lining plates.
Skived Sheet
Sliced in thin layers from molded billets, offering high flexibility and uniform thickness for insulation or anti-stick applications.
Sodium-Treated Sheet
Chemically etched on one or both sides, the sheets’ surface becomes micro-rough and chemically active, enabling strong bonding to metals, rubbers, or composites in lamination processes.
Applications
Chemical and Semiconductor Equipment
Lining for tanks, containers, ISO transport systems.
Machinery and Automation
Low-friction pads, anti-stick surfaces, and wear-resistant liners.
Construction and Automotive
Bearing pads, sealing gaskets, and expansion joint layers.
Electrical and Electronic Devices
Insulating sheets and anti-static layers.
