Thermoplastic polyurethane elastomer (TPU) jẹ iru elastomer ti o le ṣe ṣiṣu nipasẹ alapapo ati tituka nipasẹ epo. O ni awọn ohun-ini okeerẹ ti o dara julọ gẹgẹbi agbara giga, lile giga, resistance resistance ati resistance epo. O ni iṣẹ ṣiṣe ti o dara ati pe o lo pupọ ni aabo orilẹ-ede, iṣoogun, Ounjẹ ati awọn ile-iṣẹ miiran. Thermoplastic Polyurethane ni o ni meji orisi: polyester iru ati polyether iru, funfun ID ti iyipo tabi columnar patikulu, ati awọn iwuwo jẹ 1.10 ~ 1.25g/cm3. Iwọn iwuwo ibatan ti iru polyether jẹ kere ju ti iru polyester lọ. Iwọn otutu iyipada gilasi ti iru polyether jẹ 100.6 ~ 106.1 ℃, ati iwọn otutu iyipada gilasi ti iru polyester jẹ 108.9 ~ 122.8℃. Iwọn otutu brittleness ti iru polyether ati iru polyester jẹ kekere ju -62 ℃, ati iwọn otutu kekere ti iru polyether dara ju ti iru polyester lọ. Awọn ẹya ara ẹrọ ti o ṣe pataki ti polyurethane thermoplastic elastomers jẹ resistance yiya ti o dara julọ, resistance osonu ti o dara julọ, líle giga, agbara giga, elasticity ti o dara, iwọn otutu kekere, resistance epo ti o dara, kemikali kemikali ati idena ayika. Iduroṣinṣin hydrolytic ti iru ester jẹ ga julọ ju ti iru polyester lọ.
