Polyurethane chain extender is a key auxiliary raw material in the production process of polyurethane products, and is known as the "industrial MSG" in the polyurethane industry.

Polyurethane chain extender is the key for polyurethane to convert liquid raw materials into solid finished products. It is one of the three indispensable raw materials in the production process of polyurethane products, and its position in polyurethane performance materials is irreplaceable.

Within the polyurethane manufacturing industry, different downstream application fields require chain extender products of different types and properties to achieve different physical and chemical properties.
