1) Market Profile
At present, according to the use of plastics are divided into general plastics and engineering plastics two categories. General plastics generally refer to plastics with large output, wide use, good formability and low price Polyvinyl chloride, polyethylene (PE) , polystyrene (PS) , polypropylene (PP) and acrylonitrile-butadiene-styrene (ABS) plastics are the five most commonly used plastics, of which PVC is the main one.
PLASTIC AUXILIARY AGENT IS A concomitant industry of plastic industry, and its development is closely related to the development of plastic industry. PVC products are widely used in the fields of chemical building materials, agricultural PVC plastic products, industrial PVC plastic products, packaging materials, etc. .
According to the current consumption structure of PVC products in China, PVC rigid products and soft products account for 59.2% and 40.8% respectively, of which, industrial and civil construction projects are the main demand for rigid PVC, and pipe materials account for about 13.3% Profile, windows and doors accounted for 22.9% of the market share; soft products, the largest volume is the film.
Plastic processing industry with China's sustained economic prosperity to maintain high-speed growth, development potential is great. Driven by such positive factors as the state's policy of promoting energy conservation and emission reduction and the development of a circular economy, economic and technological innovation, the acceleration of the construction of a new socialist countryside, the continuous advancement of urbanization and the substantial improvement of people's living standards, and the promotion of an increase in domestic consumption, the great development of the plastics industry has been further promoted.
In recent years, with the development of the Chinese and global economy, the scale of the PVC products industry has been expanding, the output of products has been increasing year by year, the major economic and technical indicators have increased by a large margin, and the whole industry has been growing in an orderly manner It is on the way to realize the sustainable development of plastics industry from a big country to a strong country.
At present, the plastic additives industry has become an important branch of fine chemical industry, because of its various categories and functions, which run through every link of resin synthesis, plastic products processing and final application.
(2) global situation of plastic additives industry
At present, the world's enterprises engaged in the production of plastic additives are located in Asia, Europe, the United States and other continents. Large international manufacturers have been engaged in related industries for a long time due to their strong financial strength, broad technology, therefore more engaged in a variety of plastic additives production, industrial chain is longer, high-end plastic additives production proportion.
Due to the low cost of labor and large market in Asia (except Japan) , the world plastic additives industry has gradually shifted to Asia, especially China, where most of the manufacturers are concentrated. As a result, China has played an important role in the rapid growth of plastic additives in recent years, becoming the largest and fastest growing market in the world, far ahead of other countries.
In recent years, with the wide application of plastics, the global plastic additives industry has made rapid growth. In the past few years, the world demand for plastic additives has been growing at an average annual rate of about 3-4% , the demand in Europe, North America and asia-pacific (excluding China) has been growing at an average annual rate of 3% , and the average annual growth rate of plastic additives in China has been as high as 8-10% Demand elsewhere is growing at an average annual rate of 5-6 per cent. It is predicted that in the coming period, the plastic additives market will still be 3%-4% growth rate.
(3) the situation of Plastic Auxiliary Agent Industry in China
China's plastic additives industry started late, in the 1970s there were related research institutes and manufacturers engaged in plastic additives R & D, production, and with the rapid development of PVC industrialization. Now after 30 years of construction and development, China's plastic additives industry has developed into a wide range of manufacturers a large industry.
Since 2005, China's plastic additives industry annual growth rate of 8%-10% , far higher than the world's plastic additives 4% annual growth rate. The plastic auxiliary industry has also been attached importance to by various departments of the country, and has gradually become an important member in the field of new materials with the greatest development potential in recent years.
Plastic additives in the domestic industry has formed more than 30 billion yuan, in addition to most meet the needs of the domestic plastic industry, China's plastic additives exports also reached about 5 billion yuan. At the same time, through years of development, China has made great progress in the plastic additives technical level, product structure and the quality of scientific and technological personnel.
However, although there are more than 1,000 plastic additives manufacturers in China, most of them are small-scale workshop-type enterprises except plasticizers The proportion of development and development of new and high-performance auxiliaries is relatively low. However, with the upgrading of the industrial structure of China's chemical industry and the improvement of Chinese enterprises'understanding of R & D and Innovation, the number of new and high-performance plastic auxiliaries developed independently will gradually increase.
(4) the pattern of Industry Competition
After years of development, China's PVC heat stabilizer industry has formed a certain scale. At present, there are many production enterprises with a high degree of Marketization At the same time, it forms different market characteristics and competitive pattern according to different products: There are more than 300 factories that reach a certain scale. Production of lead series, stearic acid soaps, metal soaps composite stabilizers (including solid and liquid) , Organotin, organic antimony, rare earth and organic auxiliary stabilizers (Such as-diketone, phosphite, etc.) dozens of categories of products. About 43% of them are lead, 20% are metal soap, 5% are organic tin, 17% are composite, 8% are rare earth and 6% are others.
The technology of low-end products such as lead salt heat stabilizers is mature and low threshold. At present, there are many domestic manufacturers, fierce competition and the highest degree of marketization. In this situation, the poisonous lead, cadmium and even Barium are replaced by the non-toxic products, which has promoted the development of the non-toxic products.
Calcium / ZINC composite stabilizer is an important kind of non-toxic PVC heat stabilizer, and is one of the most active research and development fields in recent years. Its Research Direction is to continuously improve its thermal stability and endow it with more functional properties through the compounding of various auxiliary stabilizers, so that it can replace or partially replace some commodities developed in recent years by lead and cadmium, and can also be used in fields such as wire and cable, etc. The heat resistance has been greatly improved.
