Filler
PTFE for industrial gaskets
Chemically inert filler ideal for aggressive and high-purity media.
PTFE is close to chemically inert, resisting almost every acid, alkali, and solvent found in industrial processing. As a gasket filler and sheet material, it delivers clean, non-contaminating sealing — the reason it dominates chemical processing, pharmaceutical, and high-purity flange applications.
Key properties
- Nearly universal chemical resistance
- Non-contaminating and clean
- Low friction
- Available as virgin or expanded grades
Typical gasket uses
- PTFE sheet cut gaskets
- Spiral wound PTFE filler
- Envelope gasket jackets
- Kammprofile PTFE facing
