Tefzel HT-2129
乙烯四氟乙烯共聚物
DuPont Fluoropolymers

产品说明

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-2129 retains these traditional characteristics of Tefzel® resins while providing some new property advantages. The advantages offered by Tefzel® HT-2129 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-2129 has a temperature rating of 150°C (302°F). 总体
