WANOL F4719
This is a high-functionality, high-molecular-weight and high-activity polyether. It is suitable for the production of high-resilience flexible polyurethane slab foam, cold-cured molded foam and integral skin foam materials. It is mainly applied to manufacture automotive seat cushions, steering wheels, armrests, as well as bicycle and motorcycle saddles. It can effectively improve the comprehensive mechanical properties of polyurethane materials.
