PUR products are divided into foamed products and non-foamed products, and foamed products are soft, hard and semi-hard polyurethane foams; Non-foam products include coatings, adhesives, synthetic leather, elastomers and elastic fibers. Polyurethane material has excellent performance, wide application and various products, among which polyurethane foam is the most widely used.
Mainly used as polyurethane synthetic leather, polyurethane foam, polyurethane coating, polyurethane adhesive, polyurethane rubber (elastomer) and polyurethane fiber. In addition, polyurethane is also used in civil engineering, address drilling, mining and petroleum engineering to stop water and stabilize buildings or subgrade; As a pavement material, it is used in the runways of sports fields, indoor floors of buildings and so on.
Extended data:
Because the groups contained in PUR macromolecules are all strongly polar groups, and the macromolecules also contain polyether or polyester flexible segments, PUR has the following characteristics:
1, high mechanical strength and oxidation stability;
2. It has high flexibility and elasticity;
3. Excellent oil resistance, solvent resistance, water resistance and fire resistance.
