Technical Data

 

产品说明

DuPont™ Tefzel ® fluoropolymer 200 is a general purpose 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.

 

Typical End Products

Tefzel ® 200 is ideal for many end products, including electrical components, such as sleeving, coil forms, sockets, connectors and switches; lab ware, such as tubing, valves, containers and dishes; battery or instrument components that require chemical inertness; chemical service items, such as valve components, seal glands, pipe plugs and corrugated tubing; and film.

 

Tefzel® 200 is ASTM D3159 Type I, Grade 1.
