Industry Jingwei PVC paste resin: development space at the high end
2022-02-10
Pvc Paste Resin is widely used in artificial leather, wallpaper, ink, adhesives and many other fields. After rapid development in recent years in China, the annual productivity of the PVC paste resin industry has grown rapidly. It is expected that in 2005, domestic production will reach 220,000 tons. However, at the same time as rapid development, some issues must be seriously addressed as soon as possible. Market competition pressure In 2004, the total production capacity of domestic PVC paste resin was 270,000 tons, the output was about 208,000 tons, and the sales volume was about 206,000 tons. The domestic PVC paste resin market demand is expected to exceed 300,000 tons in 2010. Although the PVC paste resin Pvc P440 market in China is Rubber And Plastic developing rapidly, the fierce market competition is fierce. Mainly in: The first is the acceleration of energy expansion. According to statistics, during the three years from 2001 to 2003, the domestic PVC paste resin production capacity was 162,000 tons, 177,000 tons and 200,000 tons, respectively, an increase of 1.8%, 9.2%, and 12.9%, respectively. With the completion of the expansion project of several PVC paste resin installations for chlor-alkali and Shenyang Chemicals in Shanghai, this year's national production capacity may exceed 300,000 tons. The second is that the quality of products is still not satisfactory. Although China has introduced PVC paste resin production technology, there is still a certain gap compared with the world's advanced level. In particular, domestic repeated production of the same brand, the production method is relatively lagging, the production process is too single, coupled with the lack of stability of individual product quality, leading to a large number of domestic PVC paste resin backlog, on the other hand, a large number of foreign special resin influx into the country, Squeeze the domestic market. The third is the fluctuating prices. Due to the impact of power shortages and the price increase of coal and other energy sources, the price of special international crude oil fluctuates, causing the market price of PVC paste resin to fluctuate. The mainstream ex-factory price of the company was about 9,000 yuan at the beginning of 2004 and rose to 13,000 yuan in May last year, up by as much as 45%. In 2005, it fell to between 9,500 yuan and 10,000 yuan. Market space needs to expand According to statistics, although domestic PVC paste resin production capacity and output have been growing rapidly, the import volume of PVC paste resin in China is still fluctuating from 130,000 to 150,000 tons per year, and the highest import year is even close to 160,000 tons. It shows that there is still much room for the development of domestic PVC paste resins. From the application perspective, in recent years, China's automobiles, construction, toys, electronics and coatings have developed rapidly. The rapid development of these industries has brought tremendous business opportunities to the development of domestic PVC paste resin industry. Taking the automotive application field as an example, although the automotive industry was affected by energy and other aspects, in 2004 the domestic automobile production and sales totaled 5.07055 units and 5.0711 million units, which was a year-on-year increase of 14.11% and 15.50% respectively. PVC paste resin is only one type of auto glue, and it is applied in multiple applications such as chassis anti-stone hit paint, body weld sealant, spot weld glue, filter core glue, and buffer glue. According to statistics, the annual demand for four kinds of special materials developed by only one new product of vinyl chloride-vinyl acetate copolymer resin reaches 5,000 tons. In many areas, there is a big gap between China and the western developed countries. Such as wallpaper applications, Western Europe, the application of the proportion of total consumption of 15%, Japan is 44%, China is only 4%; ground plate applications, Ethylene-Vinyl Acetate Western Europe is 32%, the United States is 38%, Japan is 32%, China is only 17% Automotive applications are 15% in Western Europe, 16% in the United States, and only 8% in China. From the perspective of product structure, most of the PVC paste resins produced in China are homopolymers with very few copolymers. Homopolymer is a monomer polymerization technology, because in the application requires that the attached material has good temperature resistance, and its application development is limited. In China, all the 35 brands introduced in the earlier period were general-purpose homopolymers, but they had no copolymer grades. Copolymer is an advanced technology that can be added to the second monomer. At present, there are few domestic mastering the copolymerization technology and can produce high-end products, and the special materials developed on the basis of the copolymer technology are only a few brands. Development bottlenecks to be broken In the face of domestic Pvc Resin PVC paste resin development, it is imperative to step out from the low-end product competition as quickly as possible, eliminate outdated products, avoid the repetitive battles of the same brand, expand the market with quality, and increase sales space. On this basis, speed up the development of special materials, use technological advantages, and develop industrial advantages. To this end, experts believe that, on the one hand, it is to speed up the proportion of copolymer products. After several years of development, China's copolymer technology has made great progress, but the share is still only 35%, and its development speed has a direct impact on the development of special materials. Development still needs to be accelerated. On the other hand, the development of special materials for domestic impregnated gloves is worth paying attention to, and corresponding measures are proposed to accelerate the domestic product share. And speed up the development of high viscosity special materials, and strive to fill this gap as soon as possible.
