Tefzel 750
乙烯四氟乙烯共聚物
DuPont Fluoropolymers

產品說明

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

Tefzel ® 750 retains the traditional characteristics of Tefzel ® resins while providing some new property advantages, including increased flexibility and improved retention of properties after aging at elevated temperatures, higher limiting oxygen index, and long-term service life at higher temperatures than other Tefzel ® resins.

Underwriters Laboratories, Inc. (UL) has rated wire insulated with Tefzel ® 750 (10 mil for 600V, 6 mil for 300V) for service in appliances at a maximum continuous operating temperature of 200°C (392°F). This rating was determined under the guidelines of UL Subject 758 for appliance wiring material. Upper service temperatures for other applications should be determined under the guidelines for those applications. Temperature ratings may not be the same as the rating for appliance wire because the test procedures are different.
