Analysis on the development and competition patter

Analysis on the development situation and competition pattern of the global plastic additives industry

plastic additives, also known as plastic additives, are some compounds that must be added to improve the processability of polymers (synthetic resins) during molding processing or to improve the insufficient performance of the resin itself. For example, plasticizers are added to reduce the molding temperature of PVC resin and make products soft; Another example is to add foaming agent in order to prepare foamed plastics with light weight, vibration resistance, heat insulation and sound insulation; The thermal decomposition temperature of some plastics is very close to the molding processing temperature, so they cannot be molded without adding heat stabilizer

therefore, plastic additives play a particularly important role in plastic molding and processing. There are many ways to classify plastic additives, and the more popular way is to classify them according to their functions and functions. In the category with the same function, it is often further subdivided according to the action mechanism or chemical structure type

(I) market overview

at present, plastics are mainly divided into general plastics and engineering plastics according to their uses. General purpose plastics generally refer to those with large output, wide use, good formability and low price. Polyvinyl chloride (PVC), polyethylene (PE), polystyrene (PS), polypropylene (PP) and acrylonitrile butadiene styrene (ABS) plastics are the five most commonly used general purpose plastics, of which PVC is the main one

plastic additives are associated industries of the plastic industry, and their development is closely related to the development of the plastic industry. PVC products are widely used in the production fields of chemical building materials, agricultural PVC plastic products, industrial PVC plastic products, packaging materials, etc. with the application advantages of low cost, easy installation and use, not easy to corrosion and aging, and good thermal insulation performance

according to the current consumption structure of PVC products in China, PVC hard products and soft products account for 59.2% and 40.8% respectively. Among them, industrial and civil construction engineering is the main demand for hard PVC, with pipes accounting for about 13.3% and profiles, doors and windows accounting for 22.9% of the market share; Among soft products, the largest amount is film

with China's sustained economic prosperity, the plastic processing industry has maintained rapid growth and great development potential. The great development of the plastic industry has been further promoted by the national policies to promote energy conservation and emission reduction and the development of circular economy, economic and technological innovation, the accelerated development of the construction of a new socialist countryside, the continuous promotion of urbanization, the substantial improvement of people's living standards, and the rise of domestic consumption

in recent years, with the development of China's and the global economy, the scale of PVC products industry has been expanding, the product output has increased year by year, the main economic and technical indicators have increased significantly, and the whole industry has developed and expanded in an orderly manner. It is moving forward along the road of sustainable development to realize the plastic industry from a large country to a powerful country

at present, plastic additives have numerous categories and functions, which run through all links of resin synthesis, plastic product processing and final application. Plastic additives industry has become an important branch of fine chemical industry

(II) global plastic additives industry situation

at present, the enterprises engaged in the production of plastic additives in the world are distributed in Asia, Europe, the United States and other continents. Large international manufacturers are engaged in the production of a variety of plastic additives because of their strong financial strength, broad technology and long time in related industries. The industrial chain is long, and the production of high-end plastic additives is significant

due to the low labor cost and large market scale in Asia (except Japan), the world plastic additives industry has gradually shifted to Asia, and most manufacturers are gathered in Asia, especially in China. Therefore, China has played an important role in the rapid growth of plastic additives in recent years. It has become 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 achieved rapid growth. In the past few years, the world demand for plastic additives has continued to grow at an average annual rate of about%. The average annual growth rate of demand in Europe, North America and the Asia Pacific region (excluding China) is 3%, the average annual growth rate of plastic additives in China is as high as 8%-10%, and the average annual growth rate of demand in other regions is 5%-6%. It is predicted that the plastic additives market will continue to grow at a rate of 3% to 4% in the coming period

(III) the situation of China's plastic additives industry

China's plastic additives industry started relatively late. Only in the 1970s did relevant research institutes and manufacturers engage in the R & D and production of plastic additives, which developed rapidly with the industrialization of PVC. Now, after 30 years of construction and development, China's plastic additives industry has developed into a large industry with a complete range of manufacturers

since 2005, the average annual growth rate of China's plastic additives industry has remained at 8% - 10%, far higher than the average annual growth rate of 4% of the world's plastic additives. The plastic additives industry has also received the attention of all national departments, and has gradually become an important field of new materials with the most development potential in the recent three years. The small panel control system of various manufacturers still has many commendable skills, and the fracture of the sample is often a local member of both sides

plastic additives have formed an industry of more than 30billion yuan in China. In addition to most meeting the needs of the domestic plastic industry, the export volume of China's plastic additives has also reached about 5billion yuan. At the same time, through years of development, China has made considerable progress in the technical level of plastic additives, product structure and the quality of scientific and technological personnel

however, although there are more than 1000 plastic additives manufacturers in China, most of them are small workshop enterprises except plasticizers; The research and development of plastic additives still copy foreign mature products, and the proportion of new and high-performance additives 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, new and high-performance plastic additives independently developed will gradually increase

(IV) industry competition pattern

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, different marketization characteristics and competition patterns have been formed according to different products: there are more than 300 production plants with a certain scale. Production of lead series, stearic acid soaps, metal soap composite stabilizers (including solid and liquid), organic tin, organic antimony, rare earth and organic auxiliary stabilizers (such as β- Diketone, phosphite, etc.) dozens of products in various categories. Among them, lead accounts for about 43%, metal soap accounts for 20%, organotin accounts for 5%, compound type accounts for 17%, rare earth accounts for 8%, and others account for 6%

the technology of low-end products such as lead salt heat stabilizers is mature and the threshold is low. At present, there are many domestic manufacturers, with fierce competition and the highest degree of marketization. With the increasing awareness of environmental protection around the world, the regulations on environmental protection are becoming increasingly strict. In this situation, toxic lead, cadmium and even barium are replaced by non-toxic products, which also effectively promotes the development of non-toxic products

calcium/zinc composite stabilizer is an important variety of non-toxic PVC heat stabilizers, and it is also one of the most active research and development fields of composite stabilizers in recent years. Its research direction is to continuously improve its thermal stability and endow it with more functions 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. It can also be used in the fields of wires and cables, and the heat resistance has been greatly improved

world famous manufacturers have launched a series of products. For example, American kejuya company is mainly OBS organic stabilizer, and markobs is sold in mainland China 100 series, mainly used in PVC pipes and fittings, are powder products. Markcz series liquid and powder calcium/zinc products can be used for PVC calendering, extrusion, granulation and other composite stabilizers when the spring on the piston breaks or the elasticity is too small; German bear brand company mainly has MC series, which can be used for processing PVC wires and cables

bs series is used for dip molding, roll molding, calendering processes and products, SMS series can be used for pipes and pipe fittings products; The RX series powdered calcium/magnesium/zinc products of adico (Asahi electrochemical) Company in Japan are used for PVC profiles, and the rupl00 series are used for PVC cable materials
