SKF Ecoflon 1 is a thermoplastic material based on polytetrafluoroethylene (PTFE-virgin), which is used for back-up rings, packings, O-rings, rotary seals and gaskets. SKF Ecoflon 1 has the widest application range of all sealing materials. SKF Ecoflon 1 has an outstanding chemical resistance. When using PTFE for seals, the creeping behaviour of PTFE has to be considered. SKF Ecoflon 1 complies with FDA regulations.
