ethylene chlorotrifluoroethylene copolymer, also known as chlorotrifluoroethylene ethylene copolymer, trade name Halar. It has excellent chemical stability and outstanding radiation resistance, as well as non-flammability, good electrical properties and mechanical properties, no load conditions of long-term use temperature of -80~170 ℃, the maximum short-term use temperature can reach 200 ℃, and the total radiation dose is 5 × l04 Gy. The stability in inorganic chemicals is better than polyvinylidene fluoride, similar to FEP; The stability in organic chemicals is also better than polyvinylidene fluoride, slightly inferior to PTFE and
FEP. Its flame resistance function is better than ETFE (limiting oxygen index of the former is 60, the latter is 30), the mechanical strength is similar to that of polyamide 6, and the wear resistance is slightly inferior to that of polyamide 6, and are better than PTFE, FEP and PFA. Excellent low-temperature resistance, high low-temperature impact strength, cutting resistance
Resistance, oil resistance and weather resistance are also good. It can be processed by the molding method of general thermoplastic plastics.
ECTFE is an alternating copolymer prepared by copolymerizing ethylene and chlorotrifluoroethylene in an equal amount ratio. The preparation methods include chemical initiated polymerization, irradiation initiated polymerization and ternary copolymerization with addition of a small amount of third monomer.
can be used as wire insulation layer, cable sheath, communication satellite, nuclear reactor, spacecraft and ultra-low temperature environment in the use of electrical equipment parts, plugs and sockets and other connectors, bobbin, battery box; it can be used as a shrinkable tube for electrical appliances, aircraft coil, military wall thickness less than 0. 2mm products, and chemical pipes, containers, pumps, valves and parts, anti-corrosion lining, coating, gaskets, filter cloth, laboratory ware, hose, etc. Its film, sheet and plate extrusion products can be used as medical packaging, flat cable insulation, thin-walled structure, mechanical gear and sealing materials.
This product is packed in plastic barrels and corrugated boxes, with product certificate attached, with a net content of lOkg or 25kg per barrel. Transport non-hazardous materials, transport temperature to maintain 10 ℃ or more, to avoid sun, rain. They were stored in a dry, ventilated warehouse at room temperature above 10 °c.
can be processed by molding methods such as extrusion, injection molding, molding and transfer molding.
