What is PVC sheet

2020-12-26

PVC sheet Polyvinyl chloride Plastic is a polymer formed by free radical polymerization of vinyl chloride monomer. The English name is polyviny chloride, or PVC for short.

PVC is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder. Different additives can be added according to different purposes, and PVC plastics can present different physical and mechanical properties. Adding an appropriate amount of plasticizer to the polyvinyl chloride resin can make a variety of hard, soft and transparent products. PVC can be divided into soft PVC and hard PVC. Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains softeners (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to store, so its scope of use is limited. Rigid PVC does not contain softeners, so it has good flexibility, easy forming, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. The essence of PVC is a kind of vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film and adhesive film, which is used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounts for the largest proportion at 60%, followed by the packaging industry, and there are several other small-scale applications. According to the molecular weight, PVC can be divided into two types: general-purpose type and high-polymerization type. Our commonly used PVC resins are all universal.
