Product Description
CHLORINATED POLYVINYLCHLORIDE RESIN
(CPVC)
CPVC chlorinated method is aqueous suspension (slurry)
chlorided. Under the certain conditions using the special-purpose
PVC resin and the chloride ion Carried on the permutation
reaction to obtain the corresponding model CPVC resin. its
molecular structure is: - CHCl-CHCl-CH*-CHCl-
Because chlorinity increase, CPVC molecular not neat
increases (crystallinity in the structure to drop, molecular
chain's polar enhancement), thus causes its thermal deformation
temperature rise. The CPVC product's application temperature may
reach *****0℃, compares the PVC
enhancement ****0℃, simultaneously
improved the PVC anti-chemical properties and corrosion
resistance ability, can resist the anti-strong acid, the strong
alkali, the salt, the fatty acid salt, the oxidant,the halogen
and other chemical etching. Moreover, the CPVC tensile strength,
the anti-bending strength compares PVC also to have the
improvement. Compared with other polymer materials, CPVC has
excellent resistance to aging, corrosion resistance and high
flame resistance and so on.

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, thermostableBecause CPVC compares
PP-R, PE-X to be firm.Compared with PP, the PE-X tube,under the
similar pressure, CPVC may use a smaller caliber to achieve the
same water flow, thereby saving material costs and installation
time. Compares with other thermoplastic, CPVC has the remarkable
mechanical property under the different temperature, is suitable
for the bearing the situation, the application temperature may
reach as high as *3℃, the life may
amount to *0 years.
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 waterA 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
retardancyCPVC limiting oxygen index is *0,
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 conductivityCPVC thermal
conductivity is only 1.*5. heat is not easy to disseminate from
the pipeline, heat loss of pipeline is low.9,
bacteria breeding is not easyCPVC 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.*0, low thermal
expansionCPVC 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.
*1, the test of timenone of a thermoplastic
material such as CPVC,avoid the maintenance after *0 year hot
water system's test, and displays its excellent
performance.
