CPVC granular material is the pelletized product prepared with CPVC resin after processing. It's clear, healthful and convenient use without dirt. CPVC resin is one kind of engineering plastic with excellent performance, and prepared with PVC after chlorination, its chlorine content is increased from 56.7% in PVC to 63~69%, make the irregularity of molecule structure and the polarity of molecule chain increase, accordingly raise the heat distortion temperature. The highest service temperature of CPVC product can be up to 110 ℃ , increase 30~40 ℃ than that of PVC, in the same time, improve the anti-chemical performance and corrosion resistant performance. It can resist the chemical corrosion of acid, caustic, salt, soap, oxidant, and halogen etc. In addition, the tensile strength and bend strength are improved a lot than that of PVC. CPVC has excellent chemical resistance, corrosion resistance and flame retardance, compared with other high molecule material.

    There are many parallels between CPVC and PVC. The thermal decomposition temperature is lower and it is 100~135 ℃ . It is amorphous un-crystal material. The machining temperature of CPVC is 180~190 ℃ . Its machining scope is narrow; the melt viscosity is big and the workability is worse than that of PVC. Therefore, in order to popularize the application of CPVC and give convenience to customers for processing, we process CPVC resin into granular material to meet the demand of the market according to scientific formulation. In recent years, aiming at the intractable performance of CPVC resin, we nearly cooperated with domestic influential scientific research institutes and carried out the thorough investigation to the formulation of CPVC product and processing technical condition. We thought that process the CPVC resin into granular material for our customers could effectively settle the difficult problem of “difficult processing” and also increase the production efficiency of the customers. Accordingly, we developed two categories and five kinds of granular materials.
