Sustainability is one of the recent development themes in the polyurethane industry, and electric vehicle industry is bringing the new application requirements for polyurethane. This reflects the strong interest in sustainable products in the electric vehicle industry and will be a significant opportunity for the polyurethane industry.

The battery packaging of electric vehicle is an example of a new application of polyurethane in the field of electric vehicles. Each battery of an electric vehicle is made up of hundreds of cells, during the encapsulation process, the battery housing is filled with polyurethane foam to protect the battery from vibration and shock, while creating a seal that protects the battery from moisture, corrosives and solvents.

Foam sound-absorbing material is another growing application of polyurethane in electric vehicles, which requires new polyurethane formulations, because the noise generated by electric vehicles is different from that of gasoline-powered vehicles, requiring different foam sound-absorbing material.

In terms of adhesive, many of the challenges faced by electric vehicles are solved with innovative polyurethane adhesive, which is two-component polyurethane adhesive and can bond composite or coated metal components.

The polyurethane industry believes that the use of polyurethane in electric vehicles reflects the needs of customers for sustainability, so polyurethane companies are developing and producing actively the raw materials for polyurethane products; materials that are easier to reuse, and materials that can be recycled to meet the growing market demand for sustainability. Qichen's technical and production teams are also sparing no effort to provide polyurethane raw materials that meet the sustainable needs of electric vehicle industry.
