TPEE（热塑性聚酯弹性体）是含有聚酯硬段和聚醚软段的嵌段共聚物。其中聚醚软段和未结晶的聚酯形成无定形相聚酯硬段部分结晶形成结晶微区，起物理交联点的作用。TPEE具有橡胶的弹性和工程塑料的强度；软缎赋予它弹性使它象橡胶；硬段赋予它加工性能，使它象塑料；与橡胶相比，它具有更好的加工性能和更长的使用寿命；与工程料相比，同样具有强度高的特点，而柔韧性和动态力学性能更好。

1．力学性能，通过对软硬段比例的调节，TPEE的硬度可以从邵氏30-82D，其弹性和强度介于橡胶和塑料之间。与其它热塑性弹性体相比，在低应变条件下，TPEE模量比相同硬度的其它热塑性弹性体高。

当以模量为重要的设计条件时，用TPEE可缩小制品的横截面积，减少材料用量。TPEE具有极高的拉伸强度。与聚氨酯(TPU)相比，TPEE压缩模量与拉伸模量要高得多用相同硬度的TPEE和TPU制作同一零件前者可以承受更大的负载。在室温以上，TPEE弯曲模量很高，而低温时又不象TPU那样过于坚硬因而适宜制作悬臂梁或扭矩型部件，特别适合制作高温部件。

TPEE低温柔顺性好低温缺口冲击强度优于其他TPE，耐磨耗性与TPU相当。

I-TPEE (Thermoplastic Polyester Elastomer) yibloki kopoliymer ezi amaqela amanzima e-polyester kunye namaqela amathambo amathambo anepolyether. Isihlulo esithambileyo se-polyether kunye ne-amorphous polyester senza isihluko se-amorphous, kwaye isahluko esi se-polyether crystallizes ukwenza indawo ekristalileyo, esebenza njengendawo yokun imizimba. I-TPEE inobunzima bokunzima kwerubheri kunye namandla eeplastiki zokungcinga; Isatyani esithambileyo siyaninika ubushushu, Iyibonakala njengebhedu; Icandelo elinzima liyinika ngeziphawu zokusebenza, liyibonakala njenge plastic; Xa kuthelekiswe nerubheri, inokusebenza okungcono nokusebenza komsebenzi obude; Xa kuthelekiswa nezixhobo zobugcisa, inobubonakaliso bamandla aphezulu, ngelixa iimpawu zayo zobugcisa kunye neempawu zobugcisa zobugcisa zingcono.

1. Iimpahla zomsebenzi: Ngokulungisa ubungakanani bamahlulo amathambo nenzima, ubunzima be-TPEE bungahlukanisa ukusuka kwiShore 30-82D, kwaye ubunzima bayo nobunzima bakho bungaphakathi kwerubri ne-plastic. Compared with other thermoplastic elastomers, TPEE has a higher modulus under low strain conditions than other thermoplastic elastomers with the same hardness.

Xa i-modulus iyimeko ebalulekileyo yokuyila, ukusebenzisa i-TPEE kunganciphisa indawo yokun kwecandelo lomveliso nokunciphisa ukusetyenziswa kwempahla. I-TPEE inamandla okuxinzelela kakhulu kakhulu. Ukuthelekiswa ne-polyurethane (TPU), i-TPEE inemodulo ezingaphezulu kakhulu zocinezelo kunye neemodulo zocinezelo zoxinzelelo. Eyokuqala ingamelana nemithwalo emikhulu xa usebenzisa i-TPEE ne-TPU ngobunzima obufanayo ukwenza inxenye enye. Ngaphezu kwegumbi ubushumi obuphezulu, iTPEE inemodulo yokujika okuphezulu, kwaye kwishumi elisezantsi akunzi kunzima njengeTPU, enza ilungele ukwenza imiqadi yentsimbi okanye iingxenye zohloboue, ingakumbi ilungele ukwenza amalungu obushumi obuphezulu.

I-TPEE inobunzima obuphantsi nobunzima obulungileyo, kwaye amandla okuphumelela ubushushu obuphantsi obuphezulu kwezinye iiTPE. Ukukhusela kwembambo yayo kunokuthelekiswa neTPU.
