Fluororesin composition with excellent flexibility and cable having a dielectric layer made from the same

The present invention relates to a fluoroplastic composition having excellent flexibility and a cable including an insulating layer formed therefrom. More specifically, the present invention relates to a fluoroplastic composition and a cable including an insulating layer formed therefrom, which are excellent in heat resistance and chemical resistance so as to be used as an insulating layer material of a high heat resistance wire for a vehicle, are excellent in flexibility and abrasion durability which is an opposite relation to the flexibility, and additionally improves cold resistance, oil resistance and extrudability. The fluoroplastic composition comprises a base resin which includes a fluoroplastic having a melting point of 100 to 170°C, a fluoro rubber having a Mooney viscosity (ML1+4(100°C)) of 40 to 80 and a synthetic rubber having content of a polar monomer of 50 to 80 wt%. 본 발명은 유연성이 우수한 불소수지 조성물 및 이로부터 형성된 절연층을 포함하는 케이블에 관한 것이다. 구체적으로, 본 발명은 자동차용 고내열 전선의 절연층 소재로 사용될 수 있도록, 내열성 및 내화학성이 우수하고, 유연성 및 이와 상충관계에 있는 내마모성이 우수한 동시에, 내한성, 내유성, 압출성 등이 추가로 개선된 불소수지 조성물 및 이로부터 형성된 절연층을 포함하는 케이블에 관한 것이다.
