Open Data Verified Data
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.

HEXAFLUOROPROPYLENE-TETRAFLUOROETHYLENECOPOLYMER - Preparation Method
Open Data Verified Data
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.
- chemically initiated polymerization the organic solvent dichlorotetrafluoroethane is added to a stainless steel reaction kettle and cooled to -78 °c, and then the required ratio of high purity chlorotrifluoroethylene and ethylene are added, then add trialkyl boron ether polymerization initiator, under the action of reaction for several hours, can be prepared alternating copolymer of ethylene and chlorotrifluoroethylene, after separation, washing, drying to obtain product.
- irradiation-initiated polymerization the organic solvent trifluorotrichloroethylene is added into a stainless steel reaction kettle, and then the desired ratio of trifluorochloroethylene and ethylene monomer are added, at room temperature, 60 Co irradiation initiated copolymerization (total dose of about 5000Gy) to obtain the powdery copolymer, and then after separation and drying to obtain the product.
- in the process of ternary copolymerization, a small amount of third monomer such as allyl hexafluoroisopropyl ether or perfluoropropyl vinyl ether is added at the same time as adding the desired ratio of chlorotrifluoroethylene and ethylene, with trichloroacetyl peroxide as initiator, at 0~1 ℃ and 0. 67~1. Under the condition of 57MPa, the modified terpolymer can be prepared by reacting th.
