The main component of cpvc pipe is chlorinated polyvinyl chloride. Chlorinated polyvinyl chloride (CPVC), also known as perchlorovinyl chloride, is a product made by the substitution reaction of specific grades of polyvinyl chloride (PVC) and chlorine under the initiation of the reaction. This new type of synthetic polymer material is a white or slightly yellow flowable solid powder. The basic performance is similar to that of PVC, but the CPVC prepared by chlorination modification of PVC resin has significantly improved heat resistance, physical and mechanical properties, chemical stability and flame retardancy. It is a high-quality and low-cost project. plastic. CPVC is a new type of engineering plastic with broad application prospects.




The resin is made by chlorination modification of polyvinyl chloride (PVC) resin and is a new type of engineering plastic. The product is white or light yellow odorless, odorless, non-toxic loose particles or powder. After the PVC resin is chlorinated, the irregularity of molecular bonds increases, the polarity increases, the solubility of the resin increases, and the chemical stability increases, thereby improving the material’s heat resistance, acid, alkali, salt, oxidant, etc. corrosion. The mechanical properties of the numerical heat distortion temperature 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 ℃, and the maximum use temperature can reach 110 ℃, long-term use The temperature is 95 ℃. Among them, CORZAN CPVC has better performance indicators.
