Polyurethane foams are currently widely used. Soft foam is mainly used for various mats and soundproofing materials of furniture and vehicles; rigid foam is mainly used for heat insulation of household appliances, wall insulation, waterproof spray foam, pipe insulation materials, building plates, refrigerated trucks and cold storage. Insulation materials, etc.; semi-rigid foam for automotive dashboards, steering wheels, etc. There are various types of foam composites (two-component premixes) available on the market, mainly used for (cold curing) high resilience foams, semi-rigid foams, casting and spray hard foams. Polyurethane elastomers have high elasticity and strength, excellent wear resistance, oil resistance, fatigue resistance and vibration resistance in a wide range of hardness, and are known as "wear rubber". Polyurethane elastomers have a small output in polyurethane products, but polyurethane elastomers have excellent comprehensive properties and have been widely used in metallurgy, petroleum, automotive, mineral processing, water conservancy, textile, printing, medical, sports, food processing, construction and other industrial sectors. .
