Characters:
The CPVC resin is made by chlorination modification of PVC resin and is one advanced engineering material. This product is white or canary loose grain or powder with no smell, odorless and innocuity. After chlorination, the irregularity of molecular bond of the PVC resin and the polarity of molecular chain increase, the dissolvability and chemical stability of the resin also increase, and accordingly improve the heat resistance and resist the corrosion of acid, caustic, salt and oxidant etc. In addition, it improve the mechanical performance of numerical heat distortion temperature and chlorine content increases from 56.7% to 63-69% and Vicat softening temperature from 72-82 ℃ to 90-125 ℃ ; its highest service temperature can reach 110 ℃ and long-term service temperature can reach 95 ℃ . Accordingly, CPVC is one kind of advanced engineering plastic with vast foreground.

Application:
Chlorinated Polyvinyl Chloride Resin for Pipe.
CPVC Resin for Fitting
Tubing : CPVC is mainly used for processing tubing and hot water
delivery and corrosion medium. It can keep enough strength if the
temperature is not more than 100 ℃ and can be used for long time
under higher inteinsic pressure. The weight of CPVC is only
one-sixth of that of brass and one-fifth of steel. It has very low
thermal conductivity. Therefore, the pipe produced with CPVC has
the characters of low weight, good heat insulation performance
without heat preservation.
CPVC pipe can be used as hot sewage pipe, electroplating solution
piping, thermochemistry agent transfer piping of enterprises and
the wet chlorine transfer piping of Chlorine-Caustic plants.
Jet molding parts : CPVC resin can be used to produce the fittings
of flow pipe, filtering material, and spin-drier etc, as well as
electrical appliances and electronic parts such as wire way,
conductor protective layer, electric switch, fuse closure door and
insulation material of cable. etc.
Rolling sheet : It can be used to produce the chemical equipments
that can resist chemicals and corrosion, such as reactor, valve,
and electrolyser etc.
Compound material : the CPVC compound material that is compounded
by CPVC and certain inorganic or organic fibers has good shock
resistance and its heat resistance is better than other resin ' s
compound material. It can be produced into sheet, pipe, corrugated
plate and profile shapes etc.
CPVC can be used for modification of polyvinyl chloride fiber: the
cleaning-solarization temperature of home-made polyvinyl chloride
fiber will not be more than 60 ℃ . Adding 30% CPVC while weaving
the polyvinyl chloride fiber can greatly improve the heat
resistance of the product and reduce the shrinkage from original
50% to less than 10%.
Foaming material : The heat resistance of foaming material of CPVC
is better than that of PVC. The shrinkage at high temperature is
very small. It can be used as heat preservation material of heat
water pipe and steam pipe and so on. The retentivity to solvent of
CPVA with chlorine content more than 60% is very good. The CPVC can
be put into the solvent for foaming which can produce the gas while
heated, and you can get the homogeneous and mipor foaming gas. The
solvent such as hydrocarbon, aether and aldehyde etc with boiling
point of 50 - 160 ℃ can be used as vesicant.
Others : the crossblend of CPVC and thermoplastic or heatcurable plastic can remarkably improve the physicomechanical properties of these materials such as improve the heat resistance of the product. The foreign countries have produced the CPVC with higher impact resilience and better transparency through improvement of production technique. This kind of transparent material can be used for products of automobile, CD and audiovisual products. It has good economic benefit.
