Tefzel HT-2202
乙烯四氟乙烯共聚物
DuPont Fluoropolymers

產(chǎn)品說明

DuPont™ Tefzel® HT-2202 fluoropolymer is a special-purpose resin available in 2.5-mm (0.1-in.) pellets. Tefzel® HT-2202 is a modified ETFE resin designed to promote adhesion between polyamide resins and ETFE resins.

Tefzel® HT-2202 and the other Tefzel® fluoropolymers are melt processible, modified copolymers of ethylene and tetrafluoroethylene. They are high-performance resins that can be processed at relatively high rates compared with fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties.

Tefzel® HT-2202 is an easy-to-process adhesive material. Tefzel® HT-2202 is inert to most solvents and chemicals, hydrolytically stable, and weather resistant. Recommended upper service is 150°C (302°F); useful properties are retained at cryogenic ranges. The level and stability of dielectric properties are excellent. Mechanical properties include outstanding high-impact strength, cut-through, and abrasion resistance.
