What is polyurethane additive?
Polyurethane additives generally refer to polymer polyols and isocyanates, the main raw materials for the synthesis of polyurethane, as well as the raw materials added to meet the production process, improve material performance, increase product function, such as chain extender, catalyst, foaming agent, antistatic agent, flame retardant, surfactant, antioxidant, plasticizer, etc. During the “13th Five Year Plan” period, the types of key additives in China’s polyurethane industry were basically perfect, but there were many middle and low-grade products, and most high-performance products were produced by foreign companies. Specifically, the innovation ability of China’s polyurethane auxiliary industry is insufficient, mainly reflected in the weak basic research and application basic research; The production is mostly small and medium-sized enterprises, with low industrial concentration; Product
The quality is uneven, low-end products are seriously homogeneous, and high-end products are in short supply; The level of greening, intelligence and standardization needs to be improved, and the capacity for sustainable development is insufficient
