Plastic profiles due to the huge market demand and broad prospects for development in recent years has been the rapid development of our country, because of the intensity of competition in the market wholesale plastic pvc profiles, all plastic machinery manufacturers are considered a problem, how to ensure the quality of products By improving productivity and plastic profile products passing rate, the maximum capacity of play equipment to reduce production costs. [1] plastic profiles industry competition intensified plastic pvc profiles, large plastic profiles merger integration and capital operation is becoming more frequent pvc plastic profiles, plastic profiles of outstanding domestic manufacturers more and more attention to the market research industry, especially depth study of enterprise development environment and customer demand trends change. Because of this, a large number of outstanding domestic brands of plastic profiles plastic pvc profiles prices rise rapidly, becoming a leader in the industry of plastic profiles! Importing their vinyl chloride monomer in the main chain copolymerization, the resulting chain including two monomers section of the novel polymer, this polymer is called a copolymer. Currently copolymers of vinyl chloride with other monomers the main varieties and properties as follows: ⑴ vinyl chloride - vinyl acetate copolymer: introducing vinyl acetate monomer may function as general plasticizer, i.e. plasticized so-called "inner "avoid general plasticizer volatilization, migration, extraction and other shortcomings, but also can reduce the melt viscosity, reduce the processing temperature, to improve the processability. Usually the copolymer of vinyl acetate content of 3 to 14%. Vinyl chloride - vinyl acetate copolymer main disadvantage is that the tensile strength, heat distortion temperature, abrasion resistance, chemical stability and thermal stability decreased. ⑵ vinyl chloride - vinylidene chloride copolymer: the plasticization of the plasticized vinyl chloride copolymer of this softening temperature, solubility and molecular - vinyl acetate copolymer is substantially the same. Its biggest feature is the small water and gas permeability, high solubility in a ketone solvent, and the ability of the dilution effect of aromatics, which can be effectively used for coating. In addition, also used to make shrink films. Due to heat, light stability than the vinyl chloride - vinyl acetate copolymer difference, the higher cost of monomer, so there is no chloride in the application - vinyl acetate widely.
