The use of plasticizers must be strengthened

At present, there are nearly 200 million primary and middle school students in China, and the consumption of plastic book covers is about 1 billion in one semester. In Europe and the United States, polyethylene (PE) or polypropylene (PP) is used to make book covers, and plasticizers that are volatile in phthalates are relatively limited in relatively low-cost PVC (polyvinyl chloride) plastic products. of. In recent years, developed countries dominated by Europe and the United States have used citric acid esters, epoxy esters and other environmentally friendly plasticizers to replace traditional plasticizers, stipulating some plasticization in PVC plastic products such as packaging, medical supplies, and children's toys. Agent. China also allows the use of traditional plasticizers such as DOP and DBP. It is precisely because of the lag of relevant standards that a series of problems have arisen in the export of many plastic products in China and the large-scale entry of obsolete plasticizer products. It is urgent to solve the problem of the lag of plasticizer standards in China.

Phthalates are a type of plasticizer that primarily increases the flexibility of the book cover. The cover of PP and PE materials generally does not contain these two substances. Most of the book covers made of PVC can be detected, because PVC plus plasticizer is a relatively low-cost match, which can make the book cover meet the requirements of use. In China, affected by factors such as cost, PVC packaging materials are also widely used in various household items because the price is 40% to 50% cheaper than other plastic materials, and the market share is also the largest. The use of PVC plastic products in China is still the largest in the future. However, from the perspective of the use of plasticizers, the phthalate plasticizer products that have been restricted in developed countries and regions are very popular in China. China's relevant standards and regulations There is also a conflict between the plasticizers, and the quality of the products makes consumers feel at a loss.

The transition of new and old plasticizers should begin with a focus on consumer safety. Strict monitoring and attention to safety will lead to a decline in the market share of phthalate plasticizers such as DOP, DBP and DIBP. In 2016, China imposed restrictions on phthalate plasticizers for children's plastic toys and medical plastics for the first time. Although the market share of various “environmentally friendly” plasticizers has risen sharply in recent years, the commercialized plasticizers in China are insufficient. 50, the lack of scientific research support fatigue has seriously affected the normal development of plasticizers in China. As early as the 1980s, the EU and Japan have proved that DOP is toxic to animals. With the rapid growth of demand for green plasticizers in the market, increasing investment in science and technology, the development of non-toxic green plasticizers has become the key to sustainable development of the industry, and it is inseparable from the support of funds and policies.
