Decorative pieces began to structure, functional pieces within the current direction of development, building materials and other products from plastic. Plastic flooring, wall decoration pieces maintained a steady growth in sales, polymer construction template, waterproof material, wall supports, wall insulation panels, plastic bricks strengthen more and more applications, the growth rate is more than plastic pipe. Plastic profile industry's main products include: plastic doors and windows, plastic pipes, plastic sheets, plastic sheets for waterproofing and plastic profiles. Among them, the plastic profile, plastic pipes, plastic sheets and other products in China has formed a huge chain of chemical building materials, plastic profiles only on an annual output of 2.8 million tons of production capacity of PVC plastic board selling, China has entered the plastic big country ranks. PVC plastic is composed of liquid vinyl chloride monomer (VCM) by suspension polymerization, emulsion, bulk or solution process PVC plastic sheet products, including suspension polymerization process mature production technology, simple operation, low production costs, product variety, a wide range of applications, has been the main method of production of PVC resin, PVC production facility in the world accounts for about 90% of the proportion (in world PVC homopolymer production also accounted for about 90% ratio). Followed by emulsion method for the production of PVC paste resin. Its polymerization by a free radical initiator, the reaction temperature is generally 40 ~ 70OC PVC plastic plates, reaction temperature and concentration of the initiator of the polymerization reaction rate and the molecular weight distribution of PVC resin great influence. PVC can be divided into soft PVC and rigid PVC. Hard PVC market which accounts for about two-thirds of soft PVC 1/3. Soft PVC are generally used for surface floors, ceilings and leather, but because of soft PVC containing softener (which is soft PVC and rigid PVC difference), easy to become brittle and difficult to save, so its use has been limited. Hard PVC free softener, so flexible, easy molding, hard brittle, non-toxic and pollution-free, save for a long time PVC plastic board manufacturers, and therefore has great development and application value. Below are referred to PVC. PVC is essentially a vacuum plastic film for packaging various types of panel surface, it is also known as decorative films, with film, used in building materials, packaging, pharmaceutical and other industries. Building materials industry accounted for the largest proportion, 60%, followed by industry, packaging industry, there are a number of other small-scale applications.
