The flame retardancy of PVC film is its biggest feature

　　PVC is still one of the most commonly used plastic materials. As a polymer, its biggest feature is its good flame retardant performance, so this material is also widely used in fire protection equipment. In terms of fire prevention, PVC film is currently also used, and due to its high transparency, transparent films are often used more frequently. By comparison, many devices and devices currently use this type of PVC material, which is also an irreplaceable type of plastic material. In many cases, we have solved many problems in daily life by using products formed from PVC films.

　　This is the current value of this transparent film, and when it comes to its flame retardancy, it also has certain defects, so it needs to undergo certain treatment before it can be used normally. That is to say, two steps are required during combustion to ensure that the toxic gases released do not affect people. This is a solution to the production of hydrogen chloride or toxic gases after the combustion of this material. The main development of additives in PVC films

　　If the current development of PVC materials is still very fast, with the emergence of hard PVC and soft PVC films, it can be said that the current development of PVC is relatively stable. In fact, these are all the functions of PVC stabilizers that have emerged in recent years. When it comes to these stabilizers, it is necessary to mention some of the characteristics of PVC. As the main PVC product, it has been used in many aspects. As the main form, this PVC thin film can also be considered a good product. It has been used in car sunscreen films, mobile phone patches, skincare products, and other areas. Here, we will briefly introduce the main development of PVC materials.

　　PVC materials need to be heated to 200 ℃ for pre-treatment during use, so stabilizers that prevent thermal decomposition need to be added to the PVC material. At present, lead salt stabilizers are the most widely used PVC stabilizers in China, but there are problems that pose a threat to environmental safety. In order to comply with the international trend of lead ban in the PVC industry, China has also taken a series of measures in recent years to limit and reduce the use of lead salt stabilizers. Lead stabilizers will gradually exit the market, and PVC material production enterprises urgently need a stable, environmentally friendly, efficient, and inexpensive substitute product. The successful development of rare earth stabilizers can largely meet the demand of PVC production enterprises for environmentally friendly and efficient stabilizers.
