Analysis on the development history of plastic additives

Plastic additives, also known as plastic additives, are some of the compounds that must be added to improve the processing properties of polymers (synthetic resins) during molding or to improve the properties of the resin itself. China's plastics additives industry has developed with the development of the PVC industry. At the same time, with the development of the plastic synthetic resin industry, the application fields of the plastics auxiliaries industry have been continuously expanded, and the product variety has increased by a large margin. The plastic auxiliaries industry has become an important industry with a relatively complete range of products and a wide variety of products. The level, product structure, production scale and quality of scientific and technical personnel have made great progress, basically satisfying the demand of plastic additives in the downstream industry. At present, China's plastics auxiliaries industry has formed an industry with an output value of more than 30 billion yuan, of which about 5 billion yuan is exported.
Since 2005, the annual growth rate of China's plastics additives industry has remained at 8%-10%, far higher than the annual growth rate of 4% of the world's plastic additives. The plastics auxiliaries industry has also received the attention of various national departments and has gradually become an important member of the new material field with the most development potential in recent years. During the “Eleventh Five-Year Plan” period, with the rapid development of China's plastics industry, the production capacity, output and consumption of various plastic additives products have achieved rapid growth. The consumption of plastic additives in China from 2008 to 2010 was about 2.73 million tons, 2.82 million tons and 3 million tons respectively, and is expected to be around 3.2 million tons in 2011.
During the “Eleventh Five-Year Plan” period, China's plastics industry showed an obvious industrial cluster development trend. The number of large-scale enterprises grew rapidly, and the industrial structure gradually adjusted to the scale and intensification. The plastics additives industry is also being adjusted in the direction of scale and intensification, which is particularly evident in plasticizers, heat stabilizers, impact modifiers and processing aids.
Plastic additives are the indispensable components of general-purpose plastics engineering, high-performance engineering plastics, and the key to functionalization of synthetic resin modification. During the “Eleventh Five-Year Plan” period, the development of the whole industry is mainly concentrated on the large-scale production of general-purpose varieties. However, it rarely sees the emergence of structural innovation products. At the same time, most of the production uses patented technology from foreign companies. Therefore, the development and production of high-performance green, environmentally friendly, non-toxic and high-efficiency plastic additives have become the future development of China's plastics additives industry. The main direction of attack. Plasticizers should increase the production of non-phthalate esters, such as epoxidized soybean oil and trimellitic acid esters; stabilizers should reduce the proportion of lead salts, improve calcium/zinc composites, low-lead rare earths, hydrotalcites Class and organic heat stabilizer production; flame retardant should reduce the proportion of halogens, and vigorously develop inorganic flame retardants. At the same time, we must actively respond to EU environmental regulations, as well as domestic and foreign requirements for non-toxic environmentally friendly products. Plastic additives companies should work with universities and research institutes to change the unreasonable product structure and develop environmentally friendly additives.
