Polyurethane resin is a polymer compound, which is formed by the reaction of polyol and isocyanate. It has excellent properties, such as wear resistance, impact resistance, chemical corrosion resistance, insulation and elasticity, so it is widely used in the field of chemical production raw materials.

the nature of polyurethane resin:

1. wide range of hardness: polyurethane resin can be obtained by adjusting the proportion of raw materials and reaction conditions, different hardness products, from soft to hard can be prepared.

2. Strong wear resistance: Polyurethane resin has high wear resistance and can be used for a long time in harsh working environments.

3. Good impact resistance: Polyurethane resin has good impact resistance and can absorb and resist external impact forces.

4. Strong chemical resistance: polyurethane resin has good chemical resistance and can resist the erosion of various chemical substances.

5. Good insulation: Polyurethane resin has good insulation properties and can be used for electrical insulation materials.
The use of
polyurethane resin:

1. Coating: Polyurethane resin can be used as a coating, with excellent wear resistance, chemical resistance and decoration.

2. Adhesive: Polyurethane resin has good adhesion properties and can be used as an adhesive for bonding wood, metal, glass and other materials.

3. Elastomers: Polyurethane resins can be prepared as elastomers for use in the manufacture of tires, seals, shock absorbers, etc.

4. Thermal insulation material: Polyurethane resin has good thermal insulation performance and can be used to prepare thermal insulation materials, such as pipeline insulation, building insulation, etc.

In short, polyurethane resin has a wide range of application prospects in the field of chemical production raw materials, which can improve the performance and quality of products and promote the development of the chemical industry.
