What are the classifications of polyketone resins

Epoxy resin is formed by condensation of BPA and ECH (epichlorohydrin). This product is a colorless or light yellow viscous liquid with low toxicity. Epoxy resin has the characteristics of good chemical stability, strong adhesion and excellent electrical properties. It is used as raw materials for impregnation, casting and lamination of coatings, adhesives, FRP products and electrical and electronic components. Widely used in chemical anti-corrosion, electronics and electrical appliances, civil construction, machinery manufacturing and other fields

The chemical production capacity cycle is at the bottom, and it still has long-term investment value in the future. There has been an inflection point in China's investment consumption ratio, but from foreign experience, the chemical industry still keeps pace with GDP for a long time in the period of economic transformation, and has long-term investment value. The chemical industry has also gone through a 7-year capacity removal cycle. The overall supply and demand pattern tends to be balanced, and the profitability of the industry's leading enterprises has improved significantly. The next round of capacity expansion will be carried out among the leading enterprises with excellent operation ability in the industry.

Combined with the current situation of the industry, the next round of capacity expansion has three directions. After decades of extensive and rapid development, most sub industries of the domestic chemical industry have overcapacity, especially for chemicals with low product competitiveness, serious low-end homogenization, high risk and high pollution. Correspondingly, there is a shortage of upstream refining products of domestic petrochemical products, fine chemicals with high technical content, functional polymer materials and green processes with low emission and zero pollution. Therefore, the next round of capacity expansion in the chemical industry has great investment opportunities in three directions: improving self-sufficiency rate, industrial upgrading and industrial chain integration platform development.
