聚氨酯弹性体优异的性能特点

发布时间:2018-02-26    点击次数:

 聚氨酯弹性体优异的性能特点:
  我们是主要以研制,开发和生产--浇注型聚氨酯弹性体制品为主的生产厂家。因综合性能最好,浇注型聚氨酯的产量约占其60%以上,是应用十分广泛的最重要的聚氨酯弹性体品种。
  1,聚氨酯www.szkaiteng.com加工方式简单,方便,易于自动化,连续化生产。在浇注型聚氨酯弹性体的操作工艺生产中,原料均成液体,它们在液态下进行计量,混合,反应,直至浇注在模具中,这样有利于进行机械化连续性生产。在某种意义上讲,这种先进的液态加工过程中是对传统橡胶生产方式的一种"改革"。
  2,在目前所知的弹性体中,浇注型聚氨酯弹性体的耐磨性能是最好的。根据实验室对其磨耗性能的测定,是普通天然橡胶的3-5倍,若在有一定液体的湿磨损情况下,其耐磨性甚至比普通橡胶高出10倍,因此人们俗称为"耐磨橡胶"。
  3,浇注型聚氨酯弹性体的高耐磨性能不仅能当做普通橡胶用于抗磨损部件的制造,同时还可以在一定程度上取代传统的金属材料。良好的耐磨性,缓冲,抗冲击性,耐疲劳,耐腐蚀,低噪音等性能是传统金属的一种补充。
  4,浇注型聚氨酯弹性体的硬度变化范围广(邵A20-邵D80),在高硬度情况下仍能保持良好的弹性,这是普通塑料等材料很难具备的性能。
  5,具有优异的力学机械性能。普通天然胶,氯丁胶等的抗张强度一般都低于30Mps,但浇注型聚氨酯弹性体的抗张强度通常均大于40Mps,抗撕裂性能一般都比普通橡胶材料高很多。
  6,耐油性能优越。聚酯型聚氨酯的耐油性能可与传统橡胶中耐油性能最好的丁晴橡胶相似,而优于天然,氯丁等普通橡胶。
  7,耐氧,耐臭氧性能突出。据美国Goodyear公司对某些橡胶材料在100℃下进行160h的吸氧体积测定,天然胶92mL/g;丁苯胶18mL/g;聚氨酯0.64mL/g。
  8,符合能力高。制备中的冲弹元件,缓冲元件的承载能力高,使用过程中不会出现龟裂,而普通橡胶存在在高承载力的负荷下将会出现龟裂等缺陷。

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.szkaiteng.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.szkaiteng.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.szkaiteng.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.
