On October 20th, the “Review Conference for the Promotion of Petroleum and Chemical Industry Promotion Conference and Science and Technology Award” was held in Beijing. The meeting also issued the "Guidelines for Structural Adjustment of the Petroleum and Chemical Industry" and "Guiding Opinions on the Revitalization and Support of the Petroleum and Chemical Industry Industry". The structural adjustment of the petrochemical industry can be described as a direct hit.
Li Yongwu, president of the Petrochemical Association, said that accelerating the structural adjustment is an urgent requirement to curb the overcapacity of low-end products and promote the optimization and upgrading of industrial structure; it is an effective way to increase the efficiency of resource and energy utilization and ease the pressure on resources and energy; it is to promote cleaner production and realize The inevitable choice of the sustainable development of the industry is an important means to improve the industrial layout and increase the degree of industrial concentration. Therefore, the release of "two opinions" is of great significance to the petrochemical industry in responding to the crisis and promoting development.
He said that the publication of the guidance on the revitalization and support of the petrochemical industry has provided strong technical support for structural adjustment and industrial rejuvenation of the petroleum and chemical industries, and will provide solid technical support for advancing the oil and chemical industries to take a new road to industrialization, and put China’s oil Scientific and technological progress in the chemical industry has been raised to a new level.
"Although China has become a major petrochemical industry in the world, it is not a petrochemical powerhouse." Pan Derun, executive vice president of the Petrochemical Association pointed out at the meeting. He said that due to the extensive development model based on scale expansion for many years, the quality of industrial economic growth is not high, and the basis for growth is not solid. After years of accumulation, deep-seated conflicts within the industry have gradually emerged, especially in the international financial crisis. Under the impact, the problem of unreasonable structure was fully exposed. Therefore, structural adjustment is imminent. Pan Derun said in his speech that the “two opinions” were compiled in the context of eliminating backward production capacity, strictly controlling total production capacity of surplus products, and encouraging the development of high-end petrochemical products that are in short supply in the domestic market.
The conference was organized by the China Petroleum and Chemical Industry Association. More than 200 people including officials from the Ministry of Industry and Information Technology, the National Development and Reform Commission, the State-owned Assets Supervision and Administration Commission of the State Council, and company representatives attended the meeting.

CPE 135A

Chlorinated polyethylene is a saturated polymer material with a white powder appearance. It is non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame retardancy and coloring properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame retardant transport belt , Waterproof coiled material, film and various profiles and other products.

As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance, but it has certain disadvantages in the use of high impact and high hardness products and low temperature resistant products CPE135A. For example, in the formulation of rigid PVC, a large amount of CPE will reduce the hardness and rigidity, which reduces the physical properties of the product; in addition, when the low temperature resistance requirement of PVC products exceeds minus 30°C, CPE135A cannot meet the requirements. Under normal circumstances, modified CPE, such as ACM, RGC135A, etc., can be selected for rigidity and hardness improvement; for low-temperature resistance modification, impact-resistant ACR or other impact modifiers with lower glass transition temperature can be selected.
