Tefzel® 美国科慕ETFE HT-2202 卡扣 管材应用 乙烯四氟乙烯共聚物
GenericName: 乙烯四氟乙烯共聚物(ETFE) - 提供方: The ChemoursCompany
Description
Tefzel ™ ETFE HT-2202 is a special-purpose fluoroplastic resinavailable in 2.5-mm (0.1-in) pellets. Tefzel ™ ETFE HT-2202 is amodified ETFE resin designed to promote adhesion between polyamideresins and ETFE resins.
Tefzel ™ ETFE HT-2202 and the other Tefzel ™ fluoroplastics aremelt processible, modified copolymers of ethylene andtetrafluoroethylene. They are high-performance resins that can beprocessed at relatively high rates compared with fluorocarbonresins. They are mechanically tough and offer an excellent balanceof properties.
Tefzel ™ ETFE HT-2202 is an easy-to-process adhesive material.Tefzel ™ ETFE HT-2202 is inert to most solvents and chemicals,hydrolytically stable, and weather-resistant. Recommended upperservice is 150 °C (302 °F); useful properties are retained atcryogenic ranges. The level and stability of dielectric propertiesare excellent. Mechanical properties include outstandinghigh-impact strength, cut-through, and abrasion resistance.
Typical End Products
Tefzel ™ ETFE HT-2202 is ideal for many end products, includingelectrical components, such as sleeving, coil forms, sockets,connectors, and switches; lab ware, multi-layer tubing, valves,containers, and fasteners; battery or instrument components thatrequire chemical inertness; and mechanical parts.
