Product Description

PCTFE is a homopolymer of chlorotrifluoroethylene. It is a unique fluoropolymer that is capable of maintaining its physical properties at exceptionally low operating temperatures. It absorbs virtually no moisture, meaning it offers great dimensional stability, and maintains its electrical properties in a high humidity environment.
