PVC (polyvinyl chloride) chemical and physical properties of rigid PVC is one of the most widely used plastic materials. PVC material is a non-crystalline materials. PVC material in actual use, often by adding stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives. Runners and Gates: All conventional gate can be used. If the processing of smaller components, it is best to use the tip gate or sneak into the gate; for thicker parts, it is best to use the fan gate. The minimum diameter of the tip gate or sneak into the gate should be 1mm; fan gate thickness not less than 1mm. Typical uses of the water supply pipes, home pipes, house siding pvc plastic pipe products, business machine housings, electronics packaging, medical equipment, food packaging and other import its vinyl chloride monomer in the main chain copolymerization get is including two new polymer monomer chain links pvc plastic pipe, 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 copolymers: vinyl acetate monomer introduced can play the role of a plasticizer generally pvc plastic pipe, also known as " plasticized "to avoid volatilization general plasticizer migration out of pvc plastic pipe manufacturers and other shortcomings, but also can reduce the melt viscosity and lower processing temperature, improve processing performance. 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. pvc plastic pipe, sea Widex (certified), pvc plastic pipe provided by Qingdao Rubber Material Co., Widex.
