Product Description
I   Product Introduction
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 ºC to 90-125 ºC ; its highest service temperature can reach 110 ºC and long-term service temperature can reach 95 ºC . Accordingly, CPVC is one kind of advanced engineering plastic with vast foreground.
Because CPVC has so superior high temperature, corrosion resistance and flame retardant performance that it has been widely used in making each different industry pipeline, hot and cold pipeline and fire pipeline. The advantages of CPVC pipe can be reflected in the following areas:

1. strong thermo-stablility

2. easy installation
The connection method are very similar with PVC. Most commonly used and simple connection method is resolver cementation. Other connection methods are threaded connection, flange connection and electrode connections.

3. non-corrosive oxygen permeability
CPVC have the anti-oxygen, therefore the oxygen seepage from the radiator will not bring metal corrosion.

4. reducing the infiltration of additives

In order to prevent oxidation, some modified plastics needs to increase the massive antioxidant that may be infiltrated into the water supply system, causing the ill-smelling smell.
5. without the impact of chlorine in water
A lot of polyolefin materials (including PP, PE) may be decomposed with water, while CPVC is not affected by the impact of residual chlorine in water that there is no cracks and leakage.

6. good flame retardancy
CPVC limiting oxygen index is 60, therefore it will not burn in the air. It has the characteristics: Misfires the flame decoction, not to increase the fire set, restrict flame spread, low smoke generation.

7. CPVC has excellent chemical resistance to non-polar strong acid and alkali. Commonly used to substitute the metal to process the corrosive material, such as the poor quality of water, acidic material alkaline matter and other peroxide solutions.

8. the low thermal conductivity
CPVC thermal conductivity is only 1.05. Heat is not easy to disseminate from the pipeline, heat loss of pipeline is low.

9. bacteria breeding is not easy
CPVC is not influenced by the impact of residual chlorine in water. So it will not result in cracks and leaks. Inner wall of pipe is smooth, not easy to breed bacteria. The research indicated that the breeding of germs in CPVC pipe is far lower than other materials such as copper, steel and other plastic pipe.

10. low thermal expansion
CPVC thermal-expansion coefficient is lower than other plastics. The tube expansion is very small when tube-pass heat, unlike other types of channels (such as PP-rrp) due to the higher temperature caused by heat expansion coefficient that could cause snake bending, the existence safe hidden danger and eyesores.

11. the test of time
None of a thermoplastic material such as CPVC, avoid the maintenance after 40 year hot water system's test, and displays its excellent performance.

III   Application
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 ºC 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.
Modification of polyvinyl chloride fiber: the cleaning-solarization temperature of home-made polyvinyl chloride fiber will not be more than 60 ºC . 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 ºC 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.
