Product Description

DuPont™ Teflon® PTFE 60 X is a polytetrafluoroethylene finepowder resin used primarily for paste extrusion. Teflon® PTFE 60 Xoffers the excellent combination of properties typical of theTeflon® fluoroplastic resins:

chemical inertness to nearly all industrial chemicals andsolvents

superior in-use thermal stability (low thermal instabilityindex)

exceptional dielectric properties, stable with frequency andtemperature

toughness and flexibility

low coefficient of friction

non-stick characteristics

negligible moisture absorption

excellent weather resistance

service temperature up to 260 °C (500 °F)

useful properties at -240 °C (-400 °F)

moderate stiffness and high ultimate elongation

Teflon® PTFE 60 X is designed for processing at low to mediumreduction ratios of 10:1 to 300:1. It is designed to facilitate theproduction of high-quality, low-density tape and beading.

Teflon® PTFE 60 X meets the requirements of ASTM D 4895-10, Type I,Grade 2, Class A.
