Tefzel 210
乙烯四氟乙烯共聚物
DuPont Fluoropolymers

產品說明

DuPont™ Tefzel ® fluoropolymer 210 is a specialpurpose resin available in translucent, 2.5-mm (0.1-in) pellets. Compared to other grades of Tefzel ®, it has a higher flow rate and a lower maximum service temperature.

Tefzel ® 210 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 to fluorocarbon resins. They are mechanically tough and offer an excellent balance of properties.

The relatively high flow rate of Tefzel ® 210 makes it uniquely suitable for high speed processing, especially for extruded coatings and injection molding of slender, thin-walled or intricate shapes. Molded or extruded products made from Tefzel ® 210 are preferred for uses that do not involve significant flexural or tensile stress at elevated temperatures.

Properly processed products made from virgin Tefzel ® 210 are inert to most solvents and chemicals, hydrolytically stable and weather resistant. Recommended upper service temperature is 135°C (275°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.

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.
