Polyurethane elastomer superior performance features: We are mainly for research, development and production - pouring type polyurethane elastomer products based manufacturer. Because of the best comprehensive performance , pouring polyurethanewww.cqaedi.com production is about 60% of the polyurethane elastomers, is the most important widely used polyurethane elastomer varieties. 1, processing method is simple, convenient and continuous automation production. In pouring type polyurethane elastomer operating process production, raw materials into a liquid, mixing, reaction, until in mold casting, so that is better for mechanization continuity production. In a sense, this kind of process of traditional rubber production mode is a kind of "reform". 2, Pouring polyurethane elastomer wear-resisting performance is the best. Based on the laboratory to measured the abrasion performance is higher than ordinary natural rubber 3-5 times, if in the wet wear circumstances, its wearability even 10 times higher than ordinary rubber, so people commonly referred to as "wear-resisting rubber". 3, pouring type polyurethane elastomer high wear-resisting performance can not only as ordinary rubber for resistance to wear parts manufacturing, also can instead of traditional metal materials. Good resistance to wear, buffer, impact resistance, resistance to fatigue, corrosion resistant, low noise, such as performance is the traditional metal a supplement.www.cqaedi.com 4, pouring type polyurethane elastomer has widely range hardness from shore A20 - D80 in high hardness circumstances can still keep good elasticity, this is common plastic materials such as hard to possess the performance. 5, with excellent mechanical properties. Ordinary natural rubber, neoprene etc tensile strength is general under 30Mps, but casting type polyurethane elastomer tensile strength usually are larger than 40Mps, resisting avulsion generally much higher than ordinary rubber materials. 6, oil resistant superiorwww.cqaedi.com performance. Polyester polyurethane oil resistant performance is similar with oil resistant performance of the best butadiene acrylonitrile rubber , but better than natural, synthetic etc ordinary rubber. 7, resistant to oxygen, ozone-resisting performance outstanding. According to the American Goodyear company for some rubber materials in 100 ℃ under the 160h oxygen volume measurement, the natural rubber 92mL/g, Styrenebutadiene rubber 18mL/g, Polyurethane 0.64 mL/g.
