Polyurethane products
General advantages and characteristics of polyurethane products:
1. Good wear resistance: polyurethane products have excellent wear resistance.
2, the hardness range is wide: the hardness of polyurethane products is about Shore A10-D80, while the hardness of ordinary rubber is generally in Shore A60-100. It is worth noting that the polyurethane elastomer can have an elongation of 400-800% in such a hardness range. The highest hardness of natural rubber when the elongation is 550 is Shore A70.
3. High strength and high elongation.
4, excellent oil resistance: polyurethane products have better oil resistance than cyanide rubber; aging resistance is better than natural rubber and other synthetic rubber; polyether PUR is superior to polyester PUR in resistance to hydrolysis, acid and alkali solution corrosion .
5. Polyurethane products have excellent characteristics such as light capacity, high strength, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, non-absorption, simple and quick construction, and have become the thermal insulation of industrial sectors such as construction, transportation, petroleum, chemical, electric power and refrigeration. Indispensable materials such as waterproof plugging and sealing.
For a long time, Hangzhou Dongchen Rubber Co., Ltd., a subsidiary of Hangzhou Shunhao Rubber Engineering Co., Ltd., has been committed to the innovation and research of polyurethane technology, and successfully developed a variety of special-purpose polyurethane products for users, relying on strong technical strength and fair products.
