產(chǎn)品說明
DuPont™ Tefzel ® fluoropolymer 200 is a generalpurpose resin available in translucent, 2.5-mm (0.1-in.) pellets. Compared to other grades of Tefzel ®, its most unique features are an intermediate flow rate and a balance of properties that make it suitable for a variety of processes and demanding end uses.
Tefzel ® 200 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 to fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties.
Tefzel ® 200 can perform successfully in applications where other thermoplastics are lacking in mechanical toughness, broad thermal capability, ability to meet difficult environmental conditions, or limited by fabricating problems.
Properly processed products made from virgin Tefzel ® 200 are inert to most solvents and chemicals, hydrolytically stable and weather resistant. Recommended upper service temperature is 150°C (302°F); useful properties are retained at cryogenic ranges. The level and stability of dielectric properties are excellent and the flame rating is V-0 by the UL94 method. Mechanical properties include outstanding impact strength, cut-through and abrasion resistance. High energy radiation resistance meets IEEE 383 and the resin is approved for nuclear power plant use.
Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions.
