Chlorinated polyvinyl chloride (CPVC)
Product name: chlorinated polyvinyl chloride (CPVC)
Apperance: White or light yellow loose particles or powder, odorless
Chlorinity: 61%-68%
CAS No.: 68648-82-8
Introduction:
Resin made of polyvinyl chloride (PVC) resin modified chlorinated resin is a new type of engineering plastics. PVC resin after chlorination, the molecular bond irregularities increase, the polarity increases, the solubility of the resin increases, chemical stability increased, thereby increasing the material's heat resistance, acid, alkali, salt, oxidants, etc. corrosion. Increased the mechanical properties of the numerical heat distortion temperature, the chlorine content increased from 56.7% to 63-69%, Vicat softening temperature from 72-82 ℃, (increased to 90-125 ℃), the maximum temperature up to 110 ℃, Long-term use temperature of 95 ℃. Among them, the performance index of CORZAN CPVC is better, therefore, CPVC is a kind of new engineering plastic with broad application prospect.
Main Feature:
1.Good dimensional stability
2. Low cost
3.Good weather resistance
4.Plus different proportions of plasticizer, can easily adjust the hardness

Application:
★ Pipe: CPVC is mainly used for the production of sheet, rod, pipe conveying hot water and corrosive medium, can maintain sufficient strength at no more than 100 ℃, and can be used for a long time at higher internal pressure. CPVC weighs 1/6 of brass, 1/5 of steel, and has very low thermal conductivity. Therefore, pipes made of CPVC are lightweight and have good thermal insulation without heat preservation.
★ CPVC pipe can be used as a factory hot sewage pipes, electroplating solution pipe, thermochemical reagent delivery pipe, chlor-alkali plant wet chlorine pipeline.
★ injection parts: CPVC resin can produce pipe fittings, filter materials, dehydration machines, but also can produce electrical and electronic components. Such as the trough, the conductor of the protective layer, electrical switches, fuse protection cover, cable insulation materials.
★ Rolled sheet: Can be used to manufacture chemicals, corrosion-resistant chemical equipment, such as reactors, valves, electrolyzers and so on.
★ Composites: CPVC composite made of CPVC and some inorganic or organic fibers has good impact resistance and heat resistance better than other resin composite materials, and can be made into sheet, pipe, corrugated board, profile and so on.
★ CPVC can be used for the modification of chloroprene fiber: the washing temperature of domestic chloroprene fiber must not exceed 60 ℃. Adding 30% CPVC when spinning the chloroprene can greatly improve the heat resistance and shrinkage of the product 50% down to 10% or less.
★ Foam material: CPVC foam material heat resistance is better than PVC foam material. Shrinkage at high temperature is quite small, can be used as hot water pipes, steam pipe insulation materials. The CPVC with a chlorine content of more than 60% has a very good retention of the solvent. The CPVC can be foamed in a solvent capable of generating a gas upon heating to obtain a homogeneous, microporous foaming gas which can be used as a blowing agent having a boiling point of 50 to 160 ° C Hydrocarbons, ethers, aldehydes and other solvents for blowing agent.
★ Others, CPVC and thermoplastic or thermosetting plastic blends, can significantly improve the physical and mechanical properties of these materials, such as products can improve the heat resistance and so on.
