Chemours Teflon® PTFE 850A Granular Molding Powder (discontinued **)
Categories:	Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)
Material Notes:	Teflon® PTFE white granular molding powders are ideal for molding many different end products and stock shapes. Excellent chemical resistance, electrical properties, high temperature performance, low temperature toughness, plus unique adhesion and flame resistance. Teflon® PTFE granular molding powders are processed by compressing them into a desired shape and heating them at temperatures above their melting point to consolidate the powder. Resin Characteristics: Improved free-flow pellets with high bulk density. Excellent handling resin. Uses: Automatic molding of small-to-medium-sized parts; lined pipes, valves, and fittings via isostatic molding; compression molding of sheets. Typical properties for Teflon® PTFE Granular Resin: Chemours was formed from former DuPont performance chemicals businesses, including DuPont Fluoroproducts, in 2015.
