[China coating information] for many years, some of the main raw materials required for the production of adhesives and sealants in China are in short supply, need to be imported in large quantities, and the prices are rising. This has become the main factor restricting the development of domestic adhesive industry. The shortage of raw materials not only squeezes the profit margin of adhesive enterprises, but also limits the expansion of production scale and the improvement of scientific and technological level. At the same time, some new adhesives with high added value need insufficient raw materials, which has seriously affected the product upgrading and structural adjustment of the whole industry

it has been learned recently that it is not far for the adhesive industry to get rid of this raw material dilemma. At the press conference held not long ago, China Adhesive Industry Association said that with the launch of domestic new and expansion projects, the shortage of raw materials in the adhesive industry is alleviating

it is reported that the raw materials in short supply in the domestic adhesive and sealant industry include basic organic raw materials, synthetic resins and petroleum resins. According to the data provided by China Adhesive Industry Association, in 2006, China imported 123000 tons of acrylate. This equipment is an electronic universal testing machine made by Shandong Sida high-tech mechanical equipment Co., Ltd. for the production of subway doors for the Rail Transit Department, with a value of 180million US dollars; The import of vinyl acetate is 215000 tons, with an amount of nearly 200million US dollars; The imported EVA resin (ethylene vinyl acetate resin) is 368000 tons, with an amount of nearly 500million US dollars. From then on to today; Nearly 40000 tons of imported VAE lotion (vinyl acetate ethylene copolymer lotion) with an amount of USD 38.098 million; The imported MDI (xylene diisocyanate) is 129000 tons, with an amount of nearly US $300million; Imported TDI (toluene diisocyanate) is 163000 tons, with an amount of USD 350million; 13000 tons of imported HDI (hexamethylene diisocyanate) with an amount of US $43.951 million; 169000 tons of imported polysiloxane, with an amount of 620million US dollars; 19000 tons of imported neoprene, amounting to USD 47.579 million; Import 275000 tons of epoxy resin, amounting to 860million US dollars. These are the main raw materials produced by adhesive and sealant enterprises

China Adhesive Industry Association said that in recent years, driven by demand, a number of chemical raw material projects have been built and expanded across the country, which will provide guarantee for the raw material supply of the adhesive industry

the first solution to the problem of supply shortage is acrylic acid and ester monomers. In recent years, due to the continuous expansion of the production scale of Yang Ba company, Formosa Plastics Ningbo Company, Shenyang paraffin chemical company and other enterprises, acrylic acid and ester monomers have been able to meet the demand. This year, supply even began to exceed demand. Compared with 2005, the price of aircraft cabin glass decreased

it is expected that the shortage of raw materials for adhesives and sealants will be comprehensively improved after 2008. With the commissioning of the 300000 t/a Jinan gold ring stiffness tester built by Celanese in Nanjing in the second half of 2008 and the 200000 t/a device after the expansion of Beijing organic chemical plant, the tight supply of vinyl acetate monomers will change and the market price will be reduced. The situation of tight supply and rising prices of neoprene since last year will also be completely changed with the commissioning of two new units of Shanxi Datong rubber plant and Sichuan Changshou Chemical Co., Ltd. at the end of 2008. EVA and SIS (styrene isoprene styrene block copolymer) synthetic resin will not leave the market shortage until the end of the eleventh five year plan. It is preliminarily understood that Tianjin Bohai group is planning to build a set of EVA device with a capacity of no less than 50000 tons/year. PetroChina and SINOPEC are also actively preparing to build a set of EVA units with large capacity in Lanzhou Petrochemical Company and Shanghai Petrochemical Company, and will also build SIS units. The production time of these new units is from 2009 to 2010, which will greatly alleviate the shortage of raw materials for adhesives, especially hot melt adhesives in China
