If the current development of PVC materials is very fast, which produced a hard form of PVC, also produced a soft PVC film, it can be said that the current development of PVC or more stable. In fact this is development in recent years the role of a PVC stabilizer, speaking of the stabilizer, actually are going to have to say some of the features of PVC, and as the main PVC products currently used in many ways, as one of the main form, actually this kind of PVC film is also a good product, in the car sunscreen film, mobile phone sticker, protect skin to taste, etc are used, and there is to simple introduce about the main development of PVC material.
PVC material needs to be pre-treated by heating to 200℃ when it is used, so it is necessary to add a stabilizer to prevent thermal decomposition in PVC material. At present, lead salt stabilizer is the most widely used PVC stabilizer in China, but it is harmful to environmental safety. In order to comply with the trend of banning lead in the international PVC industry, China has taken a series of measures in recent years to restrict and reduce the use of lead salt stabilizer. Lead stabilizer will gradually withdraw from the market. PVC material manufacturers urgently need a stable effect and environmentally friendly, efficient and cheap alternative products. The successful development of rare earth stabilizer can to a great extent meet the demand of PVC production enterprises for environmental protection and high efficiency stabilizer.
