PTFE - Polytetrafluorethylene

Teflon is registered as a Trademark of the DuPont company for the polytetrafluoroethylene fiber (PTFE). Teflon is resistant to all acids and alkalis. The filtering bags made of fabrics Teflon are used in extremly unfavourable chemical and temperature conditions.
This fabric keeps a high mechanical resistance and stability of dimensions at operating temperatures not higher than 250 �C.
It can be used in all branches of industry.
