0.5mm~10mm Thickness expanded PTFE sheets
Expanded PTFE sheets is engineered with a uniform node-fibril microstructure, delivering low creep, high compressibility, and exceptional chemical resistance. It performs reliably as a sealing and insulating material in harsh industrial environments.

Glass-lined reactors, old storage tanks, and heat exchangers often have flanges that are pitted, warped or out-of-flatness by more than 0.8 mm. Filled PTFE and rubber gaskets fail here every time. Our 100% expanded ptfe sheets compresses over 45% and literally “eats” those surface defects, creating a leak-free seal at only 15–20 N·m bolt torque.
