It is often used for applications at relatively high temperatures such as hot water supply pipes near 80 ° C. However, if it is used for a long time as a hot water supply pipe, hot water deterioration may occur, resulting in destruction. Specifically, such a phenomenon appears as expansion deterioration and cracking due to water absorption.

来のもつ強度が発現され難くなる。Generally, the chlorinated vinyl chloride resin has a high tensile strength as compared with a normal vinyl chloride resin due to its rigid molecular chain, but has a drawback that it has poor impact resistance. This is because the workability of the chlorinated vinyl chloride resin is poor, that is, it is difficult to disintegrate the chlorinated vinyl chloride resin particles and to fuse the resin particles together. In addition, since the chlorinated vinyl chloride resin has poor kneading properties, it causes poor gelation, making it difficult to exhibit the original strength of the resin.

There was a problem that was added. Due to such an excessive load, the shearing between the resins increases and the heat generation becomes high, the resin is decomposed during the molding process, and the thermal stability of the molded body is lost.

The compatibility with vinyl chloride resin is good, and the strength of vinyl chloride resin can be exhibited without impairing moldability. However, in the case of adding chlorinated polyethylene to vinyl chloride resin, in order to perform molding at high temperature and high shear,
