Polyurethane can be used to manufacture plastics, rubber, fiber, hard and soft foam plastics, adhesives and coatings, etc., can be used in people's life in each domain, the application range is very wide.
1. polyurethane foam material: divided into hard polyurethane foam, semi-hard polyurethane foam and soft polyurethane foam material. Rigid polyurethane foam is mainly used for building heat insulation materials, thermal insulation materials (such as thermal insulation of pipeline facilities), articles of daily use (bedding materials such as bed, sofa, refrigerator, air conditioning insulation layer and surfboard core material), as well as transportation (automobile, aircraft, railway vehicle cushion, ceiling and other materials).
2. polyurethane elastomer: polyurethane elastomer has good tensile strength, tear strength, impact resistance, wear resistance, weather resistance, hydrolysis resistance, oil resistance and other advantages. Mainly used for coating materials (such as hose, gasket, wheel belt, roller, gear, pipe protection), edge body, sole and solid tire, etc.
3. polyurethane waterproof material: the use of polyurethane waterproof material is very convenient, can be mixed in the field, coating after normal temperature moisture curing, you can get a waterproofing layer with no seams, rubber elasticity and good performance. And easy to repair after damage. Generally used as paving material, track and field track material, racetrack, park ground material, thermal insulation window frame and so on.
4. polyurethane coating: polyurethane coating has strong adhesion, coating film has excellent wear resistance, water resistance and drug resistance, etc. Mainly used in furniture paint, building materials paint and industrial printing ink.
5. polyurethane adhesive: by adjusting the ratio of isocyanate and polyol to achieve the adjustment of the properties of the cured material, so that it can achieve high adhesion to the substrate, excellent water resistance, oil resistance and chemical resistance. Polyurethane adhesive is mainly used in packaging, construction, wood, automotive, footwear and other industries.
6. Biomedical materials: Polyurethane is widely used as a biomedical material because of its excellent biological compatibility. It can be used in the manufacture of artificial cardiac pacemaker, artificial blood vessel, artificial bone, artificial esophagus, artificial kidney, artificial dialysis membrane, etc.
7. Industrial and mining machinery polyurethane material: polyurethane wear resistance in industrial and mining machinery industry is very sought after, such as industrial sealing ring, roller; Mining machinery applications are, polyurethane sieve plate (screen), polyurethane cyclone, polyurethane roller frame, polyurethane impeller, polyurethane pulley lining block, etc
