★ Pipe material: CPVC is mainly used to produce plates, bars and pipes to transport hot water and corrosive media. It can maintain sufficient strength when the temperature does not exceed 100 ℃, and can be used for a long time under high internal pressure. The weight of CPVC is 1/6 of brass and 1/5 of steel, and it has very low thermal conductivity. Therefore, pipes made of CPVC are light in weight, good in thermal insulation, and do not need thermal insulation. ★ CPVC pipes can be used as hot sewage pipes, electroplating solution pipes, thermochemical reagent pipes, and wet chlorine pipes in chlor alkali plants. ★ Injection molded parts: CPVC resin can produce pipe fittings for water supply pipes, filter materials, dehydrators, etc., as well as electrical and electronic parts. Such as wireway, protective layer of conductor, protective cover of electric switch, fuse, insulation material of cable, etc. ★ Calendered sheet: It can be used to manufacture chemical equipment resistant to chemicals and corrosion, such as reactors, valves, electrolyzers, etc. ★ Composite material: CPVC composite material composed of CPVC and some inorganic or organic fibers has good impact resistance and heat resistance, which is also better than other resin composites, and can be made into plates, pipes, corrugated plates, profiled materials, etc. ★ CPVC can be used for the modification of chlor fiber: the washing and drying temperature of domestic chlor fiber shall not exceed 60 ℃. Adding 30% CPVC in the spinning of chlor fiber can greatly improve the heat resistance of the product, and the shrinkage rate is reduced from 50% to below 10%. ★ Foaming material: the heat resistance of CPVC foaming material is better than that of PVC foaming material. The shrinkage rate at high temperature is quite small, which can be used as thermal insulation material for hot water pipes and steam pipes. CPVC with chlorine content more than 60% has good solvent retention. CPVC can be foamed in the solvent that can generate gas when heated to obtain uniform and microporous foaming gas. Hydrocarbon, ether, aldehyde and other solvents with boiling point of 50-160 ℃ can be used as foaming agent. ★ Others, the blending of CPVC with thermoplastic or thermosetting plastics can significantly improve the physical and mechanical properties of these materials, such as improving the heat resistance of products. ★ CPVC with higher impact resistance and better transparency has also been prepared by improving the production process abroad. This transparent material can be used in automobiles, optical discs, audio-visual products, and has good economic benefits.
