The market demand for polyurethane chain extenders continues to increase, and the industry will need to continue to upgrade in the direction of high-end products in the future.

Chain extenders, also known as chain extenders, refer to compounds that can promote the extension and expansion of molecular chains. They are one of the key additives for polymer materials. Polyurethane (PU), as a widely used polymer compound, is mainly produced by reacting raw materials such as isocyanate groups, polyisocyanates, and polyester polyols with catalysts, cross-linking agents, foaming agents, chain extenders and other additives. become.

The chain extender used to generate polyurethane is referred to as a polyurethane chain extender, which refers to a compound containing two functional groups. According to different chemical structures, polyurethane chain extenders can be divided into two categories: alcohol chain extenders and amine chain extenders. The main products include glycol chain extender series, alkylene diarylamine chain extender series, delayed chain extender series, etc. Chain agent, oligomer diarylamine chain extender series, secondary amine chain extender series, etc.

Polyurethane chain extenders can adjust the reaction speed, increase physical strength, optimize performance, and improve stability of polyurethane products. They are one of the key additives for polyurethane products. Polyurethane products are widely used in packaging, home furnishing, daily necessities, home appliances, construction, automobiles, aviation and other fields. In recent years, against the background of the continuous expansion of the domestic polyurethane products market, the market demand for polyurethane chain extenders has continued to increase. The market size of my country’s polyurethane products in 2021 will be 229.14 billion yuan. Therefore, according to the“China’s Polyurethane Chain Extender Industry Market In-depth Assessment and 2022-2026” released by the Industrial Research Center The Annual Investment Feasibility Consultation Report shows that my country’s market demand for polyurethane chain extenders in 2021 will be approximately 2.586 million tons.

Driven by the continued growth in domestic market demand for polyurethane chain extenders, its related technologies have also been continuously improved, which in turn has accelerated the speed of product replacement. After development in recent years, some polyurethane chain extender products with good performance, high cost performance and moderate reaction speed have continued to appear, such as MOCA, HQEE, 740M, E-100, HER, etc. Among them, MOCA is currently the mainstream product in the domestic polyurethane chain extender market. Its related technology is relatively mature and its application fields are relatively wide.

From the perspective of the market structure, because the polyurethane chain extender industry in North America and Western Europe started earlier and their corporate technology, experience, and brand reserves are sufficient, the high-end market for polyurethane chain extenders in my country is still dominated by foreign companies, with major companies Including Seika Co., Ltd., Evonik Industries, LANXESS Group, etc. However, in recent years, under the background of rapid development of the national economy, my country has become one of the major producers and consumers of polyurethane in the world. The domestic polyurethane chain extender industry is in a stage of rapid development. Local companies mainly include Xiangyuan New Materials, Huatian Rubber and Plastic Technology wait.

Industrial Analysts personnel said that currently some domestic polyurethane chain extenders have been fully localized, but in the new high-performance polyurethane chain extenders In the market, local companies still occupy a relatively small market share. In the future, local polyurethane chain extender companies will need to continuously improve their technical level and increase product innovation capabilities, thereby promoting the continuous upgrading of the industry in the direction of high performance, high quality, and green environmental protection.
