★ Pipe: CPVC is mainly used for the production of pipes, conveying hot water and corrosive media. It can maintain sufficient strength when it does not exceed 100 °C, and can be used for a long time under high internal pressure. The weight of CPVC is 1/6 of that of yellow copper and 1/5 of steel, and it has extremely low thermal conductivity. Therefore, the pipe made of CPVC is light in weight, good in heat insulation and does not require heat preservation.
★ CPVC pipe can be used as hot water pipe, electroplating solution pipe, thermochemical reagent conveying pipe, wet chlorine gas conveying pipe of chlor-alkali plant.
★ Injection molded parts: CPVC resin can produce pipe fittings for water supply pipes, filter materials, dewatering machines, etc., and can also produce electrical and electronic parts. Such as wire troughs, protective layers of conductors, electrical switches, protective covers for fuses, insulation materials for cables, etc.
★ Calendered sheet: It can be used to manufacture chemical and chemical resistant equipment such as reactors, valves and electrolytic cells.
★ Composite material: CPVC composite material composed of CPVC and some inorganic or organic fibers has good impact resistance and heat resistance is better than other resin composite materials. It can be made into sheet, pipe, corrugated board and profiled materials.
★ CPVC can be used for the modification of polyvinyl chloride fiber: the washing temperature of domestically produced polyvinyl chloride fiber should not exceed 60 °C, and adding 30% CPVC when spinning polyvinyl chloride can greatly improve the heat resistance of the product, and the shrinkage rate is 50% of the drop to less than 10%.
★ Foaming material: The heat resistance of CPVC foaming material is better than that of PVC foaming material. The shrinkage rate at high temperatures is quite small, and it can be used as a heat insulating material for hot water pipes and steam pipes. CPVC with a chlorine content of more than 60% has a good solvent retention. CPVC can be foamed in a solvent that generates gas when heated, and a uniform, microporous foaming gas can be obtained. The boiling point is 50-160 °C. A solvent such as a hydrocarbon, an ether or an aldehyde is used as a foaming agent.
★ Others, blending CPVC with thermoplastic or thermosetting plastics can significantly improve the physical and mechanical properties of these materials, such as improved heat resistance of the product.
★ In foreign countries, CPVC with higher impact resistance and better transparency has been prepared through the improvement of production technology. This transparent material can be used in automobiles, optical discs and audio-visual products, and has good economic benefits.
