description Product Description
This chemical is primarily used as a precursor in the production of polyurethane foams, coatings, adhesives, and elastomers. Its reactive isocyanate groups allow it to form strong polymers when combined with polyols, making it valuable in creating flexible and durable materials. In the automotive industry, it is utilized in seat cushions, headrests, and interior panels due to its ability to provide comfort and resilience. In construction, it is applied in insulation foams, contributing to energy efficiency. Additionally, it is used in adhesives and sealants for bonding various materials in industrial and consumer applications. Its versatility also extends to protective coatings for surfaces that require resistance to abrasion, chemicals, and weathering.
