Riteflex TPE-E is Ticona's trade name for a series of thermoplastic polyester elastomers (TPE-E). These combine the favorable characteristics of vulcanized rubber products with the easy processability of thermoplastics. The molecular structure is made up of soft polyether components that alternate with hard polyester components. The degree of hardness is controlled through the relative proportion of the soft phase to the hard phase.

TPEE的耐寒性也是非常优异的，可以说大部分的TPEE材料都能够用在零下40度的低温环境下被长期的使用，它的脆点低于零下70摄氏度，在这样的低温环境下，硬度也会稍低，TPEE材料无论是高温环境下还是低温环境下，都变现出很好的均衡性能，所以它的被应用范围是非常宽的，基本上都能够在低温70摄氏度，高温200度的这样一个大范围的温度跨度内被长期使用，TPEE对大多数有机溶剂，燃料及气体的抗溶胀性能和抗渗透性能是好的，TPEE塑胶材料在很多不同的环境条件下，像是在水雾或者臭氧还有室外大气老化等条件下，都能表现出很好的化学稳定性优良，就像是绝大多数弹性体一样，它在紫外线的光合作用下也会发生一定的降解，因此对于需要被放置于室外的应用或者是一些制品需要受到阳光照射的条件下，在生产的时候，能够在配方中添加适量的紫外光防护助剂，像是炭黑和各种颜料或其它屏蔽材料之类的。
