Recently, the project of expanding the annual output of 60,000 tons of polyurethane new materials by Asahi Chemical Industry (Suzhou) Co., Ltd. officially started in Taicang, Jiangsu. The project will build multiple new polyurethane new material production lines with a total investment of 384 million yuan. After the project is completed and put into operation, it will effectively expand the supply of domestic high-end polyurethane new materials, alleviate the supply bottlenecks of some high-end materials, further improve the supporting capabilities of the domestic polyurethane entire industry chain, and help downstream high-end manufacturing industries reduce costs and increase efficiency.
Capacity structure split: diversified product layout of polyols environmentally friendly hot melt adhesives
The 60,000-ton capacity to be expanded this time is a multi-category combination, and the product matrix covers polyol series and environmentally friendly polyurethane hot melt adhesives: 13,000 tons of high-performance polyester polyols (2,500 tons of which are applied to in-house self-production and self-consumption), 3,000 tons of polycarbonate polyols, 14,000 tons of polymer polyester polyols, 30,000 tons of high-performance environmentally friendly polyurethane hot melt adhesives.
The product structure of the project takes into account both upstream raw materials and downstream finished items. The self-produced and self-applied polyester polyols can realize the closed supporting of internal raw materials, enhance the overall production economy, and external items are sold to the market.
High-end material highlights: polycarbonate polyols have significant performance advantages
Among them, polycarbonate polyol is a high-end polyol category. Compared with traditional polyester polyols, the material has obvious advantages in key indicators such as hydrolysis resistance, weather resistance and mechanical strength, and is a high value-added raw material in the polyurethane sector chain. The items are mainly supplied to high-end synthetic leather, automotive interiors, high-end adhesives and other fields, and are suitable to downstream scenarios with stringent durability standards such as automobiles and high-end synthetic materials.
High-performance environmentally friendly polyurethane hot melt adhesives conform to the environmentally friendly direction of the sector, can be broadly applied in composite, bonding and other scenarios, and belong to low-VOCs environmentally friendly polyurethane materials.
manufacturing significance: the domestic polyurethane sector chain extends to the high-end
As the core raw material of polyurethane, polyol immediately affects the performance of downstream items. At present, the domestic general-purpose polyol capacity is sufficient, however there is still a supply gap to high-end polycarbonate polyols. The production expansion of Asahi Chemical this time is another move to domestic polyurethane companies to measure up the upstream high-end raw material link, form supporting linkage with the capacity expansion of domestic TDI, MDI and other isocyanate production capacities, make up to the shortcomings of the polyurethane sector chain, and decrease the external application on high-end polyurethane materials.
