のウエザーストリップに多く使用されている。A chlorinated vinyl chloride resin (hereinafter referred to as CPVC)
Is generally made by chlorinating a vinyl chloride resin (hereinafter, referred to as PVC). CPVC retains the flame retardant and chemical resistance properties that are said to be the advantages of PVC,
It is expected to be widely used because it improves the low heat resistance point, which is said to be a drawback. On the other hand, PVC has a major drawback that it cannot be used at temperatures of 60 to 70 ° C. or higher because of its low heat deformation temperature. On the other hand, the heat deformation temperature of CPVC is higher by 20 to 40 ° C. than that of PVC, and the heat resistance, which is a drawback of PVC, is improved. Therefore, it is widely used for automobiles, and is often used for weather strips for hermetically sealing around a window glass.
