Tefzel HT-2127
乙烯四氟乙烯共聚物
DuPont Fluoropolymers

產(chǎn)品說(shuō)明

Because they offer mechanical strength and toughness together with resistance to heat and chemicals, DuPont™ Tefzel® fluoropolymer resins are widely used to make compact wire and cable constructions that provide long, reliable service in demanding environments. In addition, Tefzel® resins offer easy processing, high specific dielectric strength, and a low coefficient of friction.

Tefzel® HT-2127 retains these traditional characteristics of Tefzel® resins while providing some new property advantages. The advantages offered by Tefzel® HT-2127 include greater flexibility, improved retention of tensile properties at elevated temperatures, reduced flammability, and long-term service life at potentially higher temperatures compared to other Tefzel® resins.

Tefzel® HT-2127 will have the same temperature rating (150°C [302°F]) as other Tefzel® resins. 總體
