What are the characteristics, properties and uses of PVC plastics?
PVC material, that is PVC, is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder. Different additives can be added according to different uses, and polyvinyl chloride plastics can exhibit different physical and mechanical properties. A variety of hard, soft and transparent products can be made by adding proper amount of plasticizer in PVC resin.
Because of its high chemical stability, it can be used to make anti-corrosion pipes, pipe fittings, oil pipes, centrifugal pumps and blowers, etc.. The wide application of hard PVC tank production in the chemical industry lining, corrugated board, building doors and windows, wall decorations and other building materials. Because of its excellent electrical insulation performance, it can be used in the electrical and electronic industries for the manufacture of plugs, sockets, switches and cables. In daily life, PVC is used in making sandals, raincoats, toys and artificial leather, etc.!
PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounted for about 2/3 of the market, soft PVC accounted for 1/3. Soft PVC is generally used for flooring, ceiling and leather surface, but because the soft PVC contains softening agent (this is the difference between soft and hard PVC PVC), crisp, not easy to save, so the range of use is limited. The hard PVC does not contain softener, therefore, the utility model has the advantages of good flexibility, easy molding, uneasy brittleness, no poison, no pollution and long storage time, so the utility model has great development and application value. The essence of PVC is a kind of vacuum blister film. It is used in the surface packing of various panels, so it is also called decorative film and adhesive film. It is applied to many fields such as building materials, packaging, medicine and so on. Among them, the building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, as well as other small range of applications.
