What is pvc? What are the main uses of pvc?
The main purpose:
1. PVC profile
Profile, profile is PVC consumption of China's largest, accounting for about PVC of the total consumption of 25%, mainly for the production of doors and windows and energy-saving materials, its application is still a large increase in the national scope. In developed countries, plastic doors and windows market share also ranked first, such as 50% in Germany, 56% in France, 45% in the United states.
2. PVC pipe
In many of the products of PVC, PVC pipes are the second main areas of consumption, the consumption accounted for about 20%. In our country, the PVC pipe is PE pipe and PP pipe development early, many varieties, excellent performance, wide application range, occupies an important position in the market.
3. PVC film
PVC films on PVC consumption ranked third, accounting for about 10%. PVC mixed with additives, plastics, with three roll or four roll calender into a predetermined thickness of a transparent or colored film, using this method of processing films become calendered film. Can also be cut, heat processing packaging bags, raincoats, tablecloths, curtains, inflatable toys etc.. The transparent film can be used for wide greenhouse, plastic greenhouse and film use. The film biaxial tension, the characteristics of heat shrinkage, can be used for packaging.
4.PVC hard wood and sheet
Stabilizer, lubricant and filler PVC, through mixing, extrusion extruder with various diameter of tubes, profiled pipe, corrugated pipe, water pipe, water pipe, used as wire casing or stair handrail. The good hot rolling sheet overlap, rigid plates can be made of various thickness. The plate can be cut into the desired shape, and then use the PVC electrode with hot air welding into various chemical resistant tank, air duct and container etc..
5.PVC soft goods
The extruder can be extruded hoses, cables, wires etc.; using injection molding machine with all kinds of mold, can be made of plastic sandals, shoes, slippers, toys, auto parts etc..
6. PVC packaging materials
PVC products for packaging containers, mainly for a variety of film and film. The PVC container mainly the production of mineral water, beverage, cosmetic bottles, but also for refined oil packaging. PVC film can be used together with other co extruded polymer laminate with low production cost, and have good barrier properties of transparent products. PVC film can also be used to stretch or shrink packaging, packaging for mattresses, cloth, toys and industrial goods.
7. PVC panels and floor
PVC sheeting is mainly used to replace aluminum sheeting. PVC floor tile except a part of PVC resin, and other components are recycled materials, adhesives, fillers and other components, mainly used in airport ground and other places hard ground.
8. PVC consumer goods
The luggage bag is made of PVC processing of traditional products, PVC is used to make all kinds of imitation leather for bags, sports products, such as basketball, soccer and football.

PVC used in many sports and entertainment products, such as toys, music and sports activities, PVC toys and sporting goods increase, due to its low production cost, easy molding and advantage.
9.PVC coating products
Artificial leather substrate is PVC confused Fuyu cloth or paper, then at 100 DEG C and plasticizing. Can also be PVC and the assistant rolled into thin film and substrate with compression bonding. No artificial leather substrate is soft sheet directly into a certain thickness by the calender, then press the pattern can be. Can be used for the production of artificial leather suitcase, bags, book covers, sofa and car seat, and floor leather, used as building floor materials.
10.PVC foam products
Soft PVC mixing, adding proper amount of foaming agent made by foaming sheet, forming foam, foam can be used as slippers, sandals, insoles, and shockproof cushioning packaging materials. Also available extruder based low foamed rigid PVC sheet and profile, can be used to replace wood, is a kind of new building material.
11.PVC transparent sheet
With the PVC impact modifier and organic tin stabilizer, mixing, plasticizing, calendering and become transparent sheet. Can be made into thin or transparent container for vacuum packaging using thermoforming packaging materials and decorative materials, is excellent.
