PVC material is not easily flammable, high strength, resistance to climate variability and excellent geometric stability. PVC oxidant, reductant and acid has a very strong resistance. However, it can be concentrated oxidizing acids such as sulfuric acid, concentrated nitric acid corrosion and does not apply to contact with aromatic hydrocarbons, chlorinated hydrocarbons occasions. PVC melt temperature during processing is a very important process parameters of plastic PVC pipe fittings, if this argument would lead to inappropriate material decomposition problem. Very poor flow characteristics of PVC plastic PVC pipe, the process is very narrow range. Especially large molecular weight PVC material more difficult to process (this material is usually added to improve the flow characteristics of lubricant) plastic PVC pipe supply, so commonly used are small molecular weight PVC material. PVC contraction rate is very low, typically 0.2 to 0.6%. PVC is dependent on the electrical properties of the polymer residue number, formulation type and amount of various additives. Also with the electrical properties of PVC heat circumstances: When heating PVC decomposition, due to the presence of chloride ions and reduce its electrical insulation, if a large amount of chloride ions can not be alkaline stabilizer (e.g. lead salts) are neutralized, will result in decreased electrical insulation properties. Unlike PVC, polyethylene, polypropylene such non-polar polymer, its electrical properties with frequency and temperature-dependent, such as the dielectric constant decreases with increasing frequency.
