From a single show to Shuangmei Zhengyan EVA resin market to fill the gap still need to be quick
Anodizing is an electrochemical finishing process that results in a durable and corrosion-resistant protective finish. In particular, aluminum is well-suited for anodizing treatments.
In contrast to other finishing processes that apply the coating or finish to the substrate, the anodizing process leverages the aluminum oxide layers that naturally occur in aluminum and increases them in thickness to form a fully integrated surface finish. Depending on the specifications of the anodizing project, the oxide layers can be thickened minimally or to more than 100 times their original thickness.
Advantages of Anodizing
1.Improved corrosion and wear resistance
2.Good aesthetic
3.Can achieve a variety of colors
4. Clear finish options are also available
5.Lower cost compared to Powder Coating
6.Extremely durable,hard,abrasion-resistant,and long-lasting.
7.Recyclable

China's Petroleum and Chemical Industry Planning Institute Chen Hongbo also analyzed that it is expected that by 2010 China's EVA resin demand will reach 700,000 to 800,000 tons. Among them, the average annual growth rate of agricultural film demand will reach 12%, which will become the most important driving force for the rapid growth of domestic demand for EVA resin. Therefore, it is imperative for China to accelerate the development of the EVA resin industry.
EVA resin is polymerized from non-polar, crystalline ethylene and strongly polar, non-crystalline vinyl acetate monomers. EVA resin has good flexibility and rubber-like elasticity, can maintain good flexibility at -50 °C, its transparency, surface gloss and chemical stability is good, anti-aging and ozone-resistant high strength, and filler Good blendability, easy coloring and molding processing, so it is very versatile. At present, the world EVA resin production has reached more than 1 million tons / year.
The performance of EVA resin is determined by the content of vinyl acetate (VA). When the VA content is below 5%, its products are mainly used in films, wire and cable, LDPE modifiers, etc.; when the VA content is 5%~ At 10%, the product mainly produces elastic film; when VA content is 20% to 28%, it is mainly used for hot-melt adhesives and coating products; when the content is 38% to 40%, it is mainly used for adhesives. produce.
Beijing Dongfang Petrochemical Co., Ltd. (formerly Beijing Organic Chemical Factory) imported the first EVA resin production plant and technology from Eni Chemical Co., Ltd. in 1993. It was put into production in February 1995 and the annual output was 40,000 tons, which filled the domestic market. Whitespace. Before 2005, Beijing Organic Chemical Plant was the only manufacturer of EVA resin in China, but they created conditions for domestic users to fully understand the product and promoted the widespread application of EVA resin in China.
In recent years, the growth rate of the consumption of EVA resin in China has developed very rapidly. In 1993, China’s apparent consumption of EVA resin was only 31,900 tons. It increased to 225,000 tons in 1999 and reached 258,000 tons in 2000. In 2003, it continued to soar to 398,000 tons in 2004. It reached 490,000 tons. According to statistics, China imported 355,000 tons of EVA resin in 2003, an increase of 21.1% over the previous year; in 2004, it imported 450,000 tons of EVA resin, an increase of 26.8% over 2003. After this year, if Yangba Company's 200,000 tons/year production capacity can reach full capacity, it is expected that the short-term domestic market gap will be slightly reduced.
However, due to the acceleration of domestic demand growth, domestic demand is expected to reach 700,000 to 800,000 tons in 2010. Therefore, if there are no new installations completed and put into production, the gap in the domestic EVA resin market will continue to increase in the next five years.
China's Injection Molding and foaming products are the largest areas of EVA resin consumption, accounting for about 65% of total consumption; film consumption ranks second, accounting for about 16% of total EVA resin consumption; hot melt adhesives ranked third This accounted for approximately 7% of total EVA resin consumption. The application of EVA resin in China is mainly for heavy bag film, composite film, food packaging film, etc. In the hot melt adhesives, it is mainly used for pressure sensitive adhesives.
It is understood that since the film made of EVA resin is superior to the film made of low density polyethylene in terms of cold resistance, light transmittance, elasticity, anti-fog and anti-aging properties, foreign agricultural films have been used 100%. Functional film containing EVA resin (trilayer or multilayer composite film). Therefore, unlike China, the largest application area of ​​EVA resin in foreign countries is thin film.
China is a big country in agriculture and the market demand for agricultural film is huge. At the same time, China is also the country with the largest horticultural cultivation area in the world today. The area covered by greenhouse films has reached 20 million mu, and the annual output of greenhouse films has reached over 700,000 tons. Therefore, experts predict that with the continuous increase in the output of functional agricultural films, the demand for EVA resin in agricultural films will increase substantially in China, and the agricultural film will become the most important driving force for the rapid growth of demand for domestic EVA resins.
