聚氨酯彈性體優異的性能特點:
  我們是主要以研制,開發和生產--澆注型聚氨酯彈性體制品為主的生產廠家。因綜合性能最好,澆注型聚氨酯的產量約占其60%以上,是應用十分廣泛的最重要的聚氨酯彈性體品種。
  1,聚氨酯www.m.zzm168.com加工方式簡單,方便,易于自動化,連續化生產。在澆注型聚氨酯彈性體的操作工藝生產中,原料均成液體,它們在液態下進行計量,混合,反應,直至澆注在模具中,這樣有利于進行機械化連續性生產。在某種意義上講,這種先進的液態加工過程中是對傳統橡膠生產方式的一種"改革"。
  2,在目前所知的彈性體中,澆注型聚氨酯彈性體的耐磨性能是最好的。根據實驗室對其磨耗性能的測定,是普通天然橡膠的3-5倍,若在有一定液體的濕磨損情況下,其耐磨性甚至比普通橡膠高出10倍,因此人們俗稱為"耐磨橡膠"。
  3,澆注型聚氨酯彈性體的高耐磨性能不僅能當做普通橡膠用于抗磨損部件的制造,同時還可以在一定程度上取代傳統的金屬材料。良好的耐磨性,緩沖,抗沖擊性,耐疲勞,耐腐蝕,低噪音等性能是傳統金屬的一種補充。
  4,澆注型聚氨酯彈性體的硬度變化范圍廣(邵A20-邵D80),在高硬度情況下仍能保持良好的彈性,這是普通塑料等材料很難具備的性能。
  5,具有優異的力學機械性能。普通天然膠,氯丁膠等的抗張強度一般都低于30Mps,但澆注型聚氨酯彈性體的抗張強度通常均大于40Mps,抗撕裂性能一般都比普通橡膠材料高很多。
  6,耐油性能優越。聚酯型聚氨酯的耐油性能可與傳統橡膠中耐油性能最好的丁晴橡膠相似,而優于天然,氯丁等普通橡膠。
  7,耐氧,耐臭氧性能突出。據美國Goodyear公司對某些橡膠材料在100℃下進行160h的吸氧體積測定,天然膠92mL/g;丁苯膠18mL/g;聚氨酯0.64mL/g。
  8,符合能力高。制備中的沖彈元件,緩沖元件的承載能力高,使用過程中不會出現龜裂,而普通橡膠存在在高承載力的負荷下將會出現龜裂等缺陷。

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.m.zzm168.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.m.zzm168.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.m.zzm168.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.
