Teftek® Encapsulated Ultraseal™

Teftek® Encapsulated Ultraseal™

Teftek® is Coating Center's encapsulation material made of a modified copolymer of tetrafluoroethylene (TFE) and another polymer, which is resistant to virtually all chemicals and has far superior tensile strength, abrasion and creep resistance than PTFE, FEP or PFA. The temperature range of Teftek®/silicone Ultraseal™ is -60°C to +160°C. The lower temperature limit of -60°C is determined by the silicone core. Teftek® will only start showing signs of low temperature embrittlement at -100°C.
