| Tefzel 280 |
 |
Tefzel 280 fluoropolymer is a premium resin available in translucent, 2.5-mm(0.1-in) pellets.
Compared with other grades of Tefzel, its most unique features are a relatively low flow rate, a greatly enhanced flex life, and resistance to environmental stress.
Tefzel 280 and the other Tefzel fluoropolymers are melt processible, modified copolymers of ethylene and tetrafluoroethylene.
They are highperformance 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 280 is preferred for applications where other thermoplastics are lacking in mechanical toughness, broad thermal capability, ability to meet unusual thermal, mechanical, and chemical environmental extremes, or limited by fabricating problems.
Examples are components and linings for the chemical industry and molded parts with metal inserts of thick sections for use at high temperatures. |
