Polytetrafluoroethylene (PTFE), commonly known as the "King of Plastics", is a polymer obtained by polymerization of tetrafluoroethylene as a monomer. White wax like, semi transparent, excellent heat and cold resistance, suitable for long-term use at -180~260℃.

PTFE film product features:
Strong chemical stability
High purity with few impurities
Good electrical insulation performance
Low friction coefficient, non stick, heat-resistant to 260 ° C, and good flame retardant performance

In the field of hydrogen energy, it can be used for thermal transfer printing of catalytic layers, preparation of flexible membrane electrodes, etc.

Recommended model: No.9001-PTFE
Thickness range: 0.025~1.0mm
Width range: 4mm~1500mm
Length range: 1Mtr~500Mtr
