Hytrel美国杜邦TPEE 5526--Characteristic characteristic
The tensile strength of TPEE is much higher than that ofpolyurethane elastomer TPU. When TPEE and TPU with the samestrength are used to make the same part, the former one can bearhigher load. Above the indoor temperature, TPEE bending modulus isvery high, which is suitable for making fixed beam or torsionmember, especially for making high-temperature member. TPEEultra-low temperature hair has good flexibility, ultra-lowtemperature vacancy impact compressive strength is better thanother TPE, and the wear resistance is very similar to TPU. TPEE hasgood fatigue resistance and is closely combined with highelasticity, so that the raw material becomes a satisfactory rawmaterial under several cycle system load applications. It issuitable for making transmission gears, rubber rods, flexiblecouplings, transmission belts, etc. Temperature resistance TPEE hasgood high temperature resistance. The higher the strength, thebetter the temperature resistance. The application temperature ofTPEE is particularly high, which can be integrated into the paintbaking temperature (150-160 ℃) of the automatic production line,and its physical performance damage is small under continuous hightemperature. When applied at about 120 ℃, the tensile strength ofTPEE is much higher than that of TPU. In addition, TPEE hasexcellent low temperature resistance. The brittle point of TPEE isless than - 70 ℃, and the lower the strength, the better the coldresistance. Most TPEE can be applied for a long time at - 40 ℃.Because of its e characteristics at high and ultra-lowtemperatures, TPEE has a wide range of ambient temperatures and canbe used at - 70-200 ℃.
Hytrel美国杜邦TPEE 5526--Aging resistance
TPEE aging resistance and aging resistance TPEE has excellentorganic chemistry stability under various external conditions suchas fog water, reactive oxygen and outdoor air. Like mostthermosetting elastomer materials TPE, it is easy to dissolve underthe effect of ultraviolet light (ultraviolet radiation below 310nmis a key element of dissolution. Therefore, according to thestandard of outdoor application or product exposure to light,ultraviolet safety protection modifier should be added to thesecret recipe, which contains carbon black and various color pastesor other radiation protection materials, ester compound rubberantioxidant and benzotriazole ultraviolet shielding agent, whichcan effectively prevent ultraviolet brittleness High resilience.The application of TPEE raw materials to the torsion spring canmake the torsion spring have a long service life and help the trainrun, accelerate, slow down and terminate stably. Unlike the torsionspring made of metal materials, it is not easy to rust, nor will itproduce vicious change under environmental standards, or lead toductile cracking and damage. Compared with plastic materials, ithas Great reusability, but also maintain good ductility.
Hytrel美国杜邦TPEE 5526特性：
TPEE抗拉强度与聚氨酯材料弹性体材料TPU对比，TPEE压缩模量与拉申应变速率要高得多，用同样强度的TPEE和TPU制做同一零件，前面一种能够承载更高的负荷。在室内温度之上，TPEE弯曲模量很高，适合制做固支梁或扭距型构件，尤其适用于制做高溫构件。TPEE超低温头发柔顺性好，超低温空缺撞击抗压强度好于别的TPE，耐磨损耗性与TPU非常。TPEE具备良好的耐疲倦特性，与高弹力特性紧密结合，使该原材料变成数次循环系统负荷应用情况下的满意原材料，适合制做传动齿轮、胶棍、柔性联轴器、传动带等。耐温性能TPEE具备良好的耐高温性能，强度越高，耐温性越好。TPEE的应用溫度特别高，能融入自动化生产线上的烘漆溫度(150-160℃)，而且它在持续高温下物理性能损害小。在120℃左右应用，TPEE抗拉强度远远地高过TPU。除此之外，TPEE还有着优异的抗低温特性。TPEE脆点小于-70℃，而且强度越低，抗寒性越好，绝大多数TPEE可在-40℃下长时间应用。因为在高、超低温时呈现出的平衡特性，TPEE的环境温度范畴十分宽，可在-70-200℃应用。
Hytrel美国杜邦TPEE 5526耐老化能：
TPEE耐老化、抗老化性TPEE在雾水、活性氧、户外空气等各种各样外部情况下，有机化学稳定性能优质。象大部分热固性弹性体材料TPE一样，在紫外线功效下易产生溶解(310nm下列的紫外线是溶解的一个关键要素，因而针对户外运用或产品受光照的标准，秘方中应加上紫外线安全防护改性剂，在其中包含碳黑和各种各样色浆或别的防辐射材料，酯类化合物橡胶防老剂和苯并三唑型紫外线屏蔽掉剂并且用，可以高效地起着防紫外线脆化。高回弹力将TPEE原材料运用到扭簧中，可使扭簧具备较长的使用期限，可以协助列车很稳定地运行、加快、降速及其终止等。和金属材料扭簧所不一样的是，它不易锈蚀、也不会在环境标准下产生恶变、或是导致延展性裂开和损害等。而与塑胶材料对比，具备很大的多次重复使用性，还能维持不错的延展性。
