Xinhe Gel Industry

Plasticizers are important additives in plastics processing, it is the largest production and consumption of processing aids. Mainly used to improve the processability of polyvinyl chloride resin, while increasing the flexibility and plasticity of the article. Also used in fiber resin, vinyl acetate resin, ABS resin and rubber processing industry occupies an important position in chemical products.

Production Status and Trends of foreign plasticizer

Since 1931 Pvc resin production industrialization, plasticizer production gained rapid development. Current world production of plasticizers than 500 species, about 100 gained widespread use. Cool phthalate plasticizer class is the core product, the total production of 80 rings.

The world today plasticizer production capacity has reached 5 million tons, of which the United States about 82 million tons, 1.5 million tons in Western Europe, Eastern Europe, 660,000 tons, 400,000 tons Central and South America, the Middle East nearly 15 million tons, 130,000 tons Oceania, Southeast Asia 830,000 tons (including China 63 million tons), Japan 530,000 tons. The United States is the world's largest marketing plasticizer country in Western Europe in 1989, consumption of plasticizer is close to 100 million tons. In 1990 the total output of 1.134 million tons of plasticizer, a record; Japan's output of 54.8 million tons. Although there are differences between countries in resources and industrial level, plasticizers variety structure are not the same, but most countries are cool to phthalate-based product category, accounting for about 80% of the average total amount of the plasticizer, the United States accounted for 68 %, Japan 87%, Western Europe accounted for 90%. Phthalate cool class, on the overall performance of DOP mainly in US consumption in 1989 accounted for 25%, Japan accounted for 56% to 60%, Western Europe 61% (Table 1-3).

DOP production in the United States phthalic vinegar in decreasing proportion. 1972 accounted for the highest male% in 1987, dropped to 26.5% in 1990, it dropped to 17.5%. The reason is that three major US ooP manufacturer (Unioncarbide, Alli head a Sisnal and WR · Graee) has given up DOp business, causing users to switch drunk isononyl phthalate (DINP) and phthalic straight drunk cool, etc. other plasticized hIJ. 1972 to 1986 15 years, the United States plasticizer annual average 793,800 tons, the total production of phthalic cool 2/3 for 529,200 tons, 907,200 tons in 1990, creating the highest record history phthalic vinegar accounted for the total proportion of plasticizer increased from 68% to 80%. Not only shows that the US market continuously strong, but also reflects the opportunity to China and other Far East exports from developing countries. US 1990 output reached 113. The plasticizer moving tons, estimated difficult to break this record in the near future. US 1990 DoP output similar to previous years (just to reduce the proportion) reached 159,000 tons, indicating years of intense debate DoP substitute, DU and p, etc. are gradually entering the market.

More than 130 small-scale plasticizer manufacturer

Just over ten thousand tons of domestic scale Qilu, Jinling, Jilin and Harbin, 15 to 16, and the rest garnered more than 5000 tons. Plant and scattered, most of the production plants away from the raw material suppliers, do not have the economies of scale, is not conducive to continuous, automated production and scientific management, is not conducive to waste management, the impact of the play to improve product quality and economic efficiency. r City] P production has gradually concentrated Qilu, Jinling, Jilin, Harbin 4 people. Its advantages and other aspects of technology and raw materials, so that other manufacturers in the production and market competitiveness of the disadvantaged, the following medium-sized plant will be forced to withdraw LK] P market. DBp production will be gradually concentrated solvent manufacturing plant, factory drunk benzene production unit will strengthen cooperation with Ding, Xin drunk production plant. Prediction small manufacturing plant will produce other varieties, act as a "Strategic decisions" role. There are also some small plants due to intense competition and converting. Plasticizer raw materials Ding drunk, drunk Sheen has been relatively tight, many manufacturers operating rate remained at fishing to 50%.
