Polyvinyl chloride pvc-sg5

1,Description:

PVC material is one of the largest plastic products production in the world, cheap, widely application, polyvinyl chloride (PVC) resin as white or light yellow powder, It can't use alone, must go through modification. PVC is the white powder of amorphous structure, the brandization degree is small, the stability of light and heat is poor. Different additives can be added to different purposes, and polyvinyl chloride plastics can show different physical properties and mechanical properties. In polyvinyl chloride resin, a suitable amount of plasticizer can be made into a variety of hard, soft and transparent products.

Polyvinyl chloride is a polymer composed of vinyl chloride monomer (VCM), its structural unit (-ch2-chcl -) n, n is polymerization degree, usually in the filed of 590-1500. In the polymerization process, because of polymerization process, reaction conditions, reactant composition, additives, and other factors, can be produced eight different types of PVC resin, and various performance of the resin is different. The amount of chloroethylene in polyvinyl chloride resin can be divided into: industrial grade, food grade and health grade. Appearance of polyvinyl chloride resin: white powder or white particle, average density: 1.40 g/cm2.  

2,Product category:

PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3.

The soft PVC usually used in floor, ceiling, and the surface of leather, but because of the soft PVC contains softening agent (which is the difference between the soft PVC and hard PVC), easy to brittle, not easy to save, so its use range was limited.

Hard PVC contains no softener, so it is flexible and easy to form. It is not brittle. It is not toxic and pollution-free. It has a long preservation time. Therefore, it has great development and application value. The essence of PVC is a vacuum plastic film, which is used in the surface packing of all kinds of panels, so it is also called decorative film and adhesive film, which is used in many industries such as building materials, packaging and medicine. The building materials industry accounts for the largest proportion of 60%, followed by packaging industry, and a number of other small-scale applications.
