The Property of Polyurethane

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

2. Excellent wear resistance: Polyurethane products have excellent wear resistance.

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 hydrolysis resistance and acid and alkali solution corrosion resistance. PUR.

4. Polyurethane products have excellent properties such as light resistance, high strength, heat insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, no water absorption, simple and fast structure, etc., and are suitable for thermal insulation in the industrial field. It turns out it is. Construction, transportation, petroleum, chemical, electric power, refrigeration and other necessary materials for waterproof plugging.

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% in this hardness range. Elongation. The higher hardness of natural rubber when the elongation is 550 is Shore A70.
