Polyvinyl chloride (PVC) is the biggest characteristic of flame retardant, so is widely used in fire protection applications.But the polyvinyl chloride (PVC) in the process of combustion will release hydrogen chloride and other toxic gases, such as dioxin.
Polyvinyl chloride (PVC) combustion can be divided into two steps.In 240 ºC to 340 ºC before burning decomposition of hydrogen chloride gas and alkadiene contain a double bond, and then in 400-470 ºC carbon burning.

PVC formability:
1. Amorphous materials, hygroscopicity, liquidity is poor, in order to improve the liquidity, prevent bubbles and appropriate drying in advance.
2. Easy to decompose, especially at high temperature in contact with the steel and copper are more likely to break down decomposition temperature (200 degrees c).Molding temperature range is small, must be strictly controlled temperature for the material.
3. Use of screw injection machine and direct the nozzle aperture should be larger, in case of blind Angle hysteresis material.
4. Mould gating system should be thick, the appropriate gate section, mould should be cooling, mould temperature 30 to 60 degrees, the material temperature 160-190.
Material characteristics:
PVC is one of the largest plastic products production in the world, cheap, wide application, polyvinyl chloride (PVC) resin as white or light yellow powder.According to the different USES can join different additives, PVC plastic can present different physical properties and mechanical properties.Add the right amount of plasticizer in PVC resin, can be made into a variety of hard, soft and transparent products.
The density of pure PVC is 1.4 g/cm3, joined the plasticizer and filler of the density of PVC plastics are generally 1.15 2.00 g/cm3.
Hard polyvinyl chloride (PVC) has good tensile, flexural, compressive strength and impact resistance, can be used as structure materials separately.
Soft PVC softness, elongation at break, cold resistance will increase, but the brittleness, hardness, tensile strength decreased.
Polyvinyl chloride (PVC) has good electrical insulation performance, can make low frequency insulation materials, the chemical stability.Due to the poor thermal stability of polyvinyl chloride (PVC), heating for a long time can lead to decompose, release HCL gas, discoloring the polyvinyl chloride (PVC), so its application scope is narrow, with temperatures between 15 ~ 55 ºC in general.
UPVC profile:
UPVC is also called the hard PVC, it is made by the polymerization of vinyl chloride monomer and amorphous thermoplastic resin with certain additives (such as stabilizer, lubricant, filler, etc.).
In addition, using additives used with other resin blend modification method, has the obvious practical value.These have CPVC resin, PE, ABS, EVA, MBS, etc.UPVC high melt viscosity, liquidity is poor, even increase injection pressure and melt temperature, the change of liquidity are slim.
In addition, the forming temperature and the thermal decomposition temperature of the resin is very close, capable of forming temperature range is very narrow, is a kind of difficult to molding material.
Features introduced:
1.light weight, convenient transportation and handling:
PVC pipe material is very light, handling, construction is convenient, the artificial can be saved.
2.good chemical resistance:
PVC pipe with excellent acid, alkali resistance, corrosion resistance, is quite suitable for the chemical industry to use.
3.small fluid resistance:
PVC pipe wall smooth, fluid resistance small, its roughness coefficient of only 0.009, is lower than other pipes, under the same flow rate, pipe diameter can be narrowed.
4. large mechanical strength:
Outside of the PVC pipe resistance to water pressure strength, compressive strength, good resistance to impact strength, etc., are suitable for all kinds of conditions of the piping engineering.
5. good electrical insulation:
PVC tube full of excellent electrical insulation, is suitable for wire, cable ducts, piping and building on the wire.
6.do not affect water quality:
PVC pipe by dissolution test confirmed that does not affect the water quality, the best tube for the tap water piping.
7.construction simple:
PVC pipe joint construction of easy quickly, so the project construction cost is low
