PTFE Sheet – Polytetrafluoroethylene
PTFE sheet offers excellent chemical resistance, low friction, and thermal stability. A reliable solution for industrial, electrical, and food-grade applications.
Designed for High-Performance Industrial Use
PTFE sheet is a chemically inert, physiologically safe fluoropolymer designed for demanding environments. It delivers superior resistance to acids, alkalis, solvents, and oxidizers, and remains dimensionally stable in extreme temperatures ranging from -190 °C to +250 °C, with chemical resistance up to 300 °C.
Its non-stick, hydrophobic surface makes it ideal for sealing, insulation, and sliding components across chemical processing, food production, electronics, and medical sectors. PTFE is available in various sizes and forms and can be easily machined or modified to meet specific application needs. We also offer technical plastic materials production for custom-made PTFE components.
Applications of PTFE Sheet
- Chemical & Mechanical Use: Ideal for gaskets, seals, sliding plates, and pump components exposed to aggressive media.
- Electrical: Suitable for insulation parts, terminal blocks, and dielectric barriers—stable up to 200 °C.
- Food & Medical: Used in non-stick surfaces, food-safe seals, and biocompatible medical components. Compliant with EU food contact regulations (Regulation 1935/2004).
Key Features of PTFE Sheet
- Resistant to Chemicals: Withstands acids, alkalis, solvents, and oxidizers.
- Wide Temperature Range: Operates from -190 °C to +250 °C, resistant up to 300 °C.
- Low Friction & Non-stick: Ideal for sliding applications and easy to clean.
- Food Grade & Inert: Safe for food, pharma, and medical use.
- Custom Reinforcement: Available with glass fiber, carbon, or MoS₂ for added durability.
