Industrial production of PVC molecular weight generally in the range of 50,000 to 110,000, with a large polydispersity, pvc plastic plate, the molecular weight increases with decreasing polymerization temperature; no fixed melting point, Taiyuan pvc plastic plate, 80 ~ 85 ℃ start softening, 130 ℃ becomes viscoelastic state, 160 ~ 180 ℃ into a viscous flow state begins; has good mechanical properties, tensile strength of about 60MPa, the impact strength of 5 ~ 10kJ / m2; has excellent dielectric properties. PVC production was the world's largest general-purpose plastics, it is widely used. In building materials, industrial products, daily necessities, floor coverings, floor tiles, leather, pipe, wire and cable, packaging films, bottles, foam materials, sealing materials, fiber, etc. are widely used. PVC can be divided into soft PVC and rigid PVC. Hard PVC market which accounts for about two-thirds, 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 distinction), 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, so it has great development and application value. Below are referred PVC. PVC is essentially a vacuum plastic film, Wuhan pvc plastic plate, the surface of the packaging for the various types of panel, Chengdu pvc plastic plate, it is also known as decorative films, with film, used in building materials, packaging, pharmaceuticals, etc. many 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. pvc plastic plate _ _ Qingdao Conte sheet pvc plastic sheet provided by the Shandong Petroleum Equipment Co.
