What are the main uses of PVC sheets
What are the main uses of PVC sheets? Polyvinyl chloride (Polyvinylchlorid,PVC).
The true color is yellowish translucent, glossy. Transparency is better than polyethylene, polystyrene, worse than polystyrene, with the dosage of different additives, divided into soft and hard polyvinyl chloride, soft products soft and tough, feel viscous, the hardness of hard products is higher than that of low density polyethylene, but lower than that of polypropylene. Albinism occurs at the inflection.
Common products: plates, pipes, soles, toys, doors and windows, wire skins, stationery, etc.
PVC can be divided into soft PVC and hard PVC. Among them, the hard PVC accounts for about 2% of the market, and the soft PVC accounts for 1%. Soft PVC is generally used in the surface of floor, ceiling and leather, but because soft PVC contains softener (which is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to preserve, so its scope of use is limited. Hard PVC does not contain softener, so it has good flexibility, easy forming, not easy to brittle, non-toxic and pollution-free, long preservation time, so it has great value in development and application. Hereinafter referred to as PVC. The essence of PVC is a kind of vacuum plastic film, which is used in the surface packaging of all kinds of panels, so it is also called decorative film and adhesive film, which is used in many industries, such as building materials, packaging, medicine and so on. Among them, the building materials industry accounts for the largest proportion, for 60%, followed by the packaging industry, as well as a number of other small-scale applications of the industry.
Typical uses: PVC is rich in raw materials (oil, limestone, coke, salt and natural gas), mature manufacturing process, low price, wide range of uses and so on. Now it has become the second largest general resin after polyethylene resin in the world, accounting for 29% of the total consumption of synthetic resin in the world. PVC is easy to process and can be processed by molding, lamination, injection molding, extrusion, Calendering, blow molding and so on. PVC is mainly used in the production of artificial leather, film, wire sheath and other plastic soft products, water supply pipes, household pipes, house wallboards, business machine shells, electronic products packaging, medical equipment, food packaging, It can also produce plastic hard products such as plates, doors and windows, valves and so on.
Other uses such as: pvc card; pvc labeling; pvc wire; pvc curtains; pvc coated electric welding mesh; pvc foam board, pvc ceiling, pvc water pipe, pvc kick line, etc., as well as threading pipe, cable insulation, plastic doors and windows, plastic bags and so on. PVC sheet products can be seen everywhere in our daily life. PVC is used to make a variety of imitation leather, for luggage, sporting goods, such as basketball, football and rugby.
