Physicochemical properties of chlorinated polyvinyl chloride:

        As a chemical raw material, chlorinated polyvinyl chloride is not common in daily life. Many people do not understand its nature. Next, we will talk about its physical and chemical properties and hope to help you.

        Chlorinated polyvinyl chloride is obtained 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 granules or powder.

        After the chlorination of the PVC resin, the irregularity of the molecular chain arrangement increases, the polarity increases, the solubility of the resin increases, and the chemical stability increases, thereby improving the heat resistance of the material and the resistance to acids, alkalis, salts, oxidants, etc. Corrosion performance. The mechanical properties of the resin's heat distortion temperature are increased, the chlorine content is increased from 56.7% to 63-69%, the Vicat softening temperature is from 72-82 °C, (up to 90-125 °C), and the maximum operating temperature is up to 110 °C. The long-term use temperature is 95 °C.
