KLINGER Soft-chem
KLINGER Soft-chem is a soft, highly compressible sealing material manufactured from expanded PTFE. Unlike conventional PTFE materials Softchem has good creep resistance and bolt torque retention properties allowing it to be used to higher temperatures and to seal higher internal pressures.
It is ideal for aggressive or toxic fluids; pharmaceutical, food and chemical industrial applications.
Key Features:
- Excellent chemical resistance
- High compressibility
- Good creep resistance
- Suitable for glass lined and enamel flanges
- Seals worn or damaged flanges
- Low bolt load requirement
- Easy to handle and cut
- Suitable for food and pharmacuetical applications
