DuPont Teflon® PTFE Grade 7A Granular Molding Powder
Subcategory: Fluoropolymer; Thermoplastic; PTFE
Close Analogs: Data provided by the manufacturer.
Key Words: Polytetrafluoroethylene; DuPont Fluoroproducts
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: High bulk density. These small particles result in the highest quality electrical and mechanical properties of all Teflon® PTFE granular molding powders. Uses: Large cylinders for making tape or sheet by skiving; large shapes for machining or direct use. Typical properties for Teflon® PTFE Granular Resin:
