What are the advantages and characteristics of polyurethane products

The chemical properties of polyurethane products such as wear resistance, oil resistance, ozone resistance, aging resistance, tear resistance, impact resistance, high elasticity, strong vibration absorption, load support ability and other physical properties. It only accounts for one-sixth of steel and has cost-effectiveness. So it is widely used in automobile production, metallurgical production, mining machinery, engineering machinery, chemical machinery and other industries.

General strengths and characteristics of polyurethane products:

1. Good wear resistance: polyurethane products have excellent wear resistance

2. Hardness scale: The hardness of polyurethane products is about Shore a10-d80, while the hardness of ordinary rubber is generally Shore a60-100. It is worth noting that the polyurethane elastomer within this hardness scale can have an elongation of 400-800%. The hardness of natural rubber is 550, and the elongation is Shore a70.

3. High strength and high elongation. Rubber-coated bearing pulley

4. Excellent oil resistance: the oil resistance of polyurethane products is better than that of butadiene cyanide rubber, the aging resistance of polyurethane products is better than natural rubber and other synthetic rubbers, and the hydrolysis resistance, acid resistance and alkali corrosion resistance of polyether polyurethane Performance is better than polyester polyurethane. Polyurethane cushion washer

5. Polyurethane products have outstanding characteristics such as light weight, heat insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, non-absorption, simple and convenient construction. , Has become an indispensable material for heat insulation, waterproofing, plugging and sealing in construction, transportation, petroleum, chemical, electric power, refrigeration and other industrial sectors.
