It is necessary to set it in the range of ~60 parts by weight. If it is less than 5%, the toughness, which is a characteristic of ethylene-fluoroolefins, will be impaired, and if it exceeds 60 parts by weight, the heat resistance will deteriorate.

範囲か好ましい。For tetrafluoroethylene-propylene copolymer, it is better to graft either styrene or acrylic acid ester, or both styrene and nisdel acrylate considering the electrical properties and heat resistance. I wonder if it will be crafted. In this case, the ratio (weight) of styrene/thiacrylic acid ester is preferably in the range of 5/1 to 1/l.

である。For the ethylene-fluoroolefin copolymer, the amount of turent of the detrafluoroethylene-propylene copolymer made from styrene and acrylic acid ester is 30 to 30.
The reason for specifying 90% heavy weight is that if it is less than 30%, it is not flexible enough, and if it exceeds 90%, ethylene-α
This is because the toughness, which is a characteristic of olefins, is lost.
