Main development of PVC film on additives
Sep 03, 2018

If the current development of PVC materials is very fast, which produced hard form of pvc, but also produced a soft PVC film, it can be said that the current development of polyvinyl chloride is relatively stable. In fact, this is the development of a PVC stabilizer in recent years, speaking of this stabilizer, in fact, we have to say some of the characteristics of pvc, and as the main PVC products have been used in many ways, as one of the main forms, in fact, this kind of PVC film is also considered to be a better product. In automobile sunscreen film, mobile phone film, skin care products have been used, and here is a brief introduction about the main development of PVC materials.

PVC materials need to be heated to 200 C for pretreatment, so it is necessary to add stabilizers to prevent thermal decomposition in PVC materials. 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 international trend of banning lead in PVC industry, China has taken a series of measures to restrict and reduce the use of lead salt stabilizers in recent years. Lead stabilizers will gradually withdraw from the market. PVC material manufacturers urgently need a good stability and environmental protection, efficient and cheap alternative products. Successful development of rare earth stabilizers can largely meet the needs of PVC manufacturers for environmentally friendly and efficient stabilizers.
