PCTFE
Polychlorotrifluoroethylene
PRODUCT DESCRIPTION
Chlorine and fluorine in the middle of this unique fluoropolymer contribute to its high compressive strength, low deformation under load and stability within a wide thermal range. PCTFE was developed and manufactured by the 3M Company under the brand name of Kel-F®. In 1995, the 3M Company discontinued manufacturing the resin and sold the rights to Daikin Industries Ltd., who now produces the resin under the brand name Neoflon® PCTFE. The actual Kel-F® product is no longer available in the marketplace.
