The pure resin of PVC is easy to decompose during processing, with low impact strength, poor fluidity and poor weather resistance, so products such as heat stabilizer, impact modifier and processing AIDS need to be added during processing. At present, there are three main impact modifiers for PVC, namely ACR, MBS and CPE.
According to the Research Report on Market Demand and Development Opportunities of PVC Impact Modifiers in China from 2020 to 2025 issued by Xinsijie Industrial Research Center, there are differences in the use of PVC impact modifiers between China and developed countries. In China, the consumption of CPE, ACR and MBS accounts for 40%, 365, 438+0% and 24% respectively, and CPE still accounts for a high proportion in China because of its low price. In developed countries, ACR and MBS occupy the main market, accounting for 58% and 32% respectively. Because the production of CPE pollutes the environment, it is gradually replaced by ACR and MBS in developed domestic markets. Generally speaking, the production of CPE is a great threat to the environment, and the product performance is worse than that of ACR and ACM, so the demand ratio in China will gradually decrease in the future, and ACR and ACM will become the mainstream products in the PVC impact modifier industry.
The main demand of PVC impact modifier comes from PVC processing. In recent years, the domestic production and demand of PVC have been increasing. In 20 19, China's PVC output was about 210.2 million tons, an increase of about 10% over the previous year, and the consumption was about 20.98 million tons, so the supply and demand tended to be balanced. Due to the increasing production and demand of PVC, the market demand of PVC impact modifier is rising, and the PVC impact modifier industry is on the rise.
CPE accounts for a relatively high proportion in China PVC impact modifier. However, due to stricter environmental supervision, the capacity growth of CPE in China has gradually slowed down in recent five years. However, in the second half of 20 19, the CPE industry ushered in technological changes, and it is expected that the domestic CPE production capacity will show a rapid growth trend in the next two years. By the end of 2022, China CPE industry plans to increase its production capacity by about 800,000 tons.
After years of development, the domestic ACR production technology is relatively mature, and the domestic ACR output is about 360,000 tons in 20 19. On the demand side, with the increasing demand for ACR for PVC and architectural decoration, the consumption of ACR is also increasing, reaching 330,000 tons in 20 19.
MBS has been used in household and household products, packaging, PVC products and other fields. Under the background of continuous technological innovation of manufacturers, the output and demand of MBS in China are increasing, reaching about 65438+ 10,000 tons in 2065.438+09. At the same time, driven by the development of downstream industries, the consumption of MBS continued to grow, reaching 260,000 tons in 2065.438+09. The supply and demand of MBS in China are unbalanced, and most of the MBS market demand depends on imports. In the future, there will be more domestic substitution space for MBS industry.
According to the industry analyst of Xinsijie, there are three kinds of impact modifiers for PVC. At present, the application demand of CPE is the highest. However, due to environmental factors, the demand for CPE will gradually decrease in the future. ACR and ACM will become the mainstream products of PVC impact modifier industry, in which the supply and demand of MBS market are unbalanced, and the domestic market demand depends on imports. This field has great potential for future development.
