Product Description

Product Description

 

PVC is amorphous white powder with small branching degree. PVC molecular weight of industrial production is generally in the range of 50,000 ~ 120,000, with a large polydispersity, molecular weight increases with the reduction of polymerization temperature; Without a fixed melting point, it begins to soften at 80 ~ 85ºC, changes to viscoelastic state at 130ºC, and changes to viscous flow state at 160 ~ 180ºC. Good mechanical properties, tensile strength about 60MPa, impact strength 5 ~ 10kJ/m²; Excellent dielectric properties. But the stability of light and heat is poor, above 100ºC or after a long time of sunlight exposure, it will decompose and produce hydrogen chloride, and further automatic catalytic decomposition, causing discoloration, physical and mechanical properties also rapidly decline, in practical applications must be added stabilizer to improve the stability of heat and light. PVC is very hard, solubility is also very poor, dichloroethane and other a few solvents, organic and inorganic acid, alkali, salt are stable, chemical stability with the use of temperature increased and decreased. 
Main purpose
1. PVC profiles
Profile, profile is the largest consumption of PVC in China, accounting for about 25% of the total consumption of PVC, mainly used for the production of doors and Windows and energy-saving materials, its should be used in the country is still a large increase. In developed country, the market share of plastic door window also is high in the first place, if Germany is 50%, France is 56%, the United States is 45%.
2. PVC pipe
In many PVC products, PVC pipe is its second largest consumption area, accounting for about 20% of its consumption. In our country, PVC pipe than PE pipe and PP pipe development early, varieties, excellent performance, wide range of use, occupy an important position in the market.
3. PVC film
PVC film field of PVC consumption ranked third, accounting for about 10%. PVC mixed with additives, plasticizing, the use of three or four roller calendering mechanism into a specified thickness of transparent or colored film, film processing in this way, become calendering film. Can also be cut, thermal processing packaging bags, raincoats, tablecloths, curtains, inflatable toys and so on. Wide transparent film can be used for greenhouse, plastic greenhouse and mulching film. The thermal shrinkage properties of bidirectional stretched films can be used for shrink packaging.
4.PVC hard materials and plates
PVC with stabilizer, lubricant and filler, after mixing, with the extruder can be extruded a variety of caliber of hard pipe, shaped pipe, bellows, used as downpipe, water pipe, wire casing or stair handrail. The laminated sheets can be overlapped and hot pressed to make hard plates of various thicknesses. The plates can be cut to the desired shape and then welded with hot air using PVC electrodes into various chemical-resistant storage tanks, air ducts and containers, etc.
