The main features and strengths of OKULEN® PTFE + PFA:
A fluoropolymer highly resistant to chemicals and temperature
Application temperatures of up to 260°C
PTFE is highly inert, and is resistant even to aggressive acids such as aqua regia
PFA has a somewhat lower maximum application temperature, but is more diffusion-resistant than PTFE
Applications include sliding elements for use at high temperatures, e.g. in chemical equipment and process containment, and preforms with or without pressed metal inserts such as impellers, pump casings, discs, etc.
