With the rapid and steady development of China's national economy, the epoxy resin industry has also made great progress. From the beginning of the 20th century to today's take-off, China's epoxy resin industry only took more than five years, during which the production volume was 2000. 60,000 tons increased to more than 300,000 tons in 2005; consumption increased from 180,000 tons in 2000 to 650,000 tons in 2005, with an average annual growth rate of 30%. China has in fact become a major growth force for global epoxy resins, driving the global epoxy resin industry to maintain high growth.
There are many epoxy resin manufacturers in China, but there are not many enterprises with a 10,000-ton scale. The main epoxy resin manufacturers in China include Guangzhou Hongchang Electronic Materials Industry Co., Ltd., Baling Petrochemical Yueyang Petrochemical Complex, Blue Star Chen New Materials Co., Ltd., Guangdong Ciba Polymer Chemical Co., Ltd., Jiangsu Sanmu Group Co., Ltd., Dalian Qihua Chemical Co., Ltd., Wuxi Di Aisheng Epoxy Co., Ltd., etc.
In 1996, China imported 40,800 tons of epoxy resin, reaching 260,000 tons in 2005. The average annual growth rate in the past 9 years was over 20%, and the growth rate was very rapid. With the rapid increase in domestic production capacity, imports have remained stable since 2004. At the same time, the production capacity of domestic epoxy resin enterprises has increased, and the export volume of China's epoxy resin has increased year by year. In 1996, the export volume was 8,600 tons, and in 2005 it increased to 77,718 tons.
There is still a certain gap between the production technology of most domestic epoxy resin enterprises and the advanced foreign technology. The main problem is that the scale of the production equipment is not economical, the product specificity is low, and the product quality is poor. In addition, the convenience of product after-sales service and application needs to be improved.
Despite this, the huge market potential still provides a space for domestic enterprises to survive and develop. It is expected that China's epoxy resin production capacity will further increase in the future. In the next 5-10 years, China's epoxy resin industry will be further standardized, and enterprises with excessive production costs, environmentally unqualified products and low product grades will be eliminated. By 2010, China's epoxy resin production capacity will remain at 600,000-700,000 tons, and there is still a certain gap in the domestic market. At the same time, the accelerated development of domestic pillar industries has brought unlimited business opportunities to the epoxy resin industry, such as the automotive sector, the information industry, the energy, transportation, and construction industries. These pillar industries are all in the process of applying epoxy resin. There is a huge market demand for epoxy resin.
