1. Polyurethane products are characterized by high strength and high elongation.

3. Excellent oil resistance: The oil resistance of polyurethane products is better than that of cyanide butadiene rubber, and its aging resistance is better than that of natural rubber and other synthetic rubbers. Polyether PUR is better than polyester in terms of resistance to hydrolysis and acid and alkali solution corrosion. PUR.

4. Polyurethane products have excellent properties such as light resistance, high strength, heat insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, non-water absorption, simple and fast structure, and are suitable for heat insulation in the industrial field. It turns out it is. Necessary materials for waterproofing and leak-proofing in construction, transportation, petroleum, chemical industry, electric power, refrigeration, etc.

5. Wide range of hardness: The hardness of polyurethane products is about Shaw A10-D80, and the hardness of ordinary rubber is generally Shaw A60-100. It is worth noting that polyurethane elastomers can have 400-800% hardness in this hardness range. Elongation. When the elongation of natural rubber is 550, the higher hardness is Shore A70.
