The biggest advantage of CPVC water supply pipe is its high temperature resistance. If there is a relatively large proportion of graphite filler in the raw materials for forming CPVC pipes, it can also be used as a heat transfer pipe. The application of this pipe in China has only begun in recent years, and it is mostly used in the water delivery, thermochemical solution and waste liquid delivery pipelines of cold and hot water. The long-term use of the infusion temperature can reach up to 120 ℃, and the service life can reach up to 40 years.

CPVC is a new type of engineering plastics with broad application prospects. The resin is a new type of engineering plastics, which is made of chlorinated polyvinyl chloride (PVC) resin. The product is white or light yellow tasteless, odorless, non-toxic loose particles or powder. After chlorination of PVC resin, the irregularity and polarity of molecular bonds increase, which increases the solubility and chemical stability of the resin, thus improving the heat resistance, acid resistance, alkali resistance, salt resistance, oxidant and other corrosion of the material. The mechanical properties of the thermal deformation temperature of the resin are improved. The chlorine content is increased from 56.7% to 63-69%, the Vicat softening temperature is increased from 72-82 ℃ to 90-125 ℃, the maximum service temperature can reach 110 ℃, and the long-term service temperature is 95 ℃. Among them, CORZAN CPVC has better performance indicators.
