Supply chlorinated polyvinyl chloride | CPVC plastic raw materials | PVC plastic raw materials

Chlorinated polyvinyl chloride (chlorinated polyvinyl chloride) is a new type of engineering plastic made from chlorine modification of polyvinyl chloride (PVC) resin. The product is white or light yellow, tasteless, odorless and non-toxic loose granules or powder. After the resin is chlorinated, the irregularity of the molecular chain arrangement increases and the polarity increases, which increases the solubility and chemical stability of the resin, thereby improving the material's heat resistance and resistance to corrosion by acids, alkalis, salts, oxidants, etc. performance. The mechanical properties of the heat distortion temperature of the resin are improved, the chlorine content is increased from 0 to 0, the Vicat softening temperature is increased from ℃ to ℃, the maximum use temperature can reach ℃, and the long-term use temperature is ℃. It is one of the few that can be used at higher temperatures and One of the polymeric materials used for a long time under higher pressure, it has excellent mechanical properties. The tensile strength ratio is increased by about 10 times, which is about 10 times higher than that of resin. Especially at close to ℃, it can still maintain strong rigidity, which can fully meet the needs of Requirements for equipment and pipelines under this temperature. It has good chemical corrosion resistance. It not only has excellent chemical corrosion resistance at room temperature, but also has good acid and alkali resistance and chemical resistance at higher temperatures. It is far better than other resins and can replace traditional materials to resist It has excellent flame retardancy for corrosive substances, has excellent flame retardant self-extinguishing properties, has a limiting oxygen index of , has the characteristics of no flame dripping, limits flame spread and smoke generation, and has a low thermal conductivity coefficient of only . Processed heat-resistant pipes have less heat loss and the insulation layer can be exempted from the influence of residual chlorine in the water. Polyolefin materials (such as polyolefin materials) may decompose when encountering residual chlorine in the water, but they will not be affected by the residual chlorine in the water. No cracks and drips. Bacteria are not easy to breed. Because the pipeline is not affected by residual chlorine in the water, its inner wall is smooth and bacteria are not easy to breed. It not only resists the erosion of all forms of bacteria but is also resistant to general sterilization chemicals. Therefore, it is a new engineering plastic with broad application prospects.

Application of chlorinated polyvinyl chloride
Mainly used in the production of pipe rolled sheets, which can be used as domestic hot and cold water supply pipes, hot sewage pipes in chemical plants, and electroplating solution pipes , thermochemical reagent conveying pipes, wet chlorine gas conveying pipes in chlor-alkali plants, and oil field crude oil conveying can be used to manufacture chemical and corrosion-resistant chemical equipment, such as reactor valves, electrolytic cells, etc. It can still maintain high strength when it does not exceed ℃, and can be used for a long time under high internal pressure. It is mainly used to produce pipe fittings for water supply pipes, filter materials, chemical tower packing, etc. It can also produce electrical and electronic parts. Such as wire trough, protective layer of conductors, electrical switches, protective covers of fuses, insulation materials of cables, etc.
