Duritaan TPU-Adayg sare TPU/ Kabaha ciribta TPU/ Xidho bikrad u adkaysata TPU

Thermoplastic polyurethane elastomer (TPU) waa nooc elastomer ah oo balaastiig lagu samayn karo kulaylinta laguna kala diri karo dareere. Waxay leedahay sifooyin dhammaystiran oo heersare ah sida xoog sare, adkeysi sare, caabbinta xirashada iyo caabbinta saliidda. Waxay leedahay wax qabad wanaagsan waxaana si weyn loogu isticmaalaa difaaca qaranka, caafimaadka, cuntada iyo warshadaha kale. Polyurethane Thermoplastic wuxuu leeyahay laba nooc: nooca polyester-ka iyo nooca polyeter-ka, qaybaha kala duwan ee koodhka ee cad, iyo cufnaanta 1.10 ~ 1.25g/cm3. Cufnaanta qaraabada ee nooca polyeter-ka ayaa ka yar kan nooca polyesterka. heerkulka kala guurka galaas ee nooca polyether waa 100.6 ~ 106.1 ℃, iyo heerkulka kala guurka galaas ee nooca polyester waa 108.9 ~ 122.8 ℃. Heerkulka jajaban ee nooca polyeter-ka iyo nooca polyester-ka ayaa ka hooseeya -62 ℃, iyo iska caabbinta heerkulka hooseeya ee nooca polyeter-ka ayaa ka fiican kan nooca polyesterka. Astaamaha aadka u wanaagsan ee elastomers-ka poliurethane waa iska caabin aad u fiican, iska caabin ozone heer sare ah, qallafsanaan sare, xoog sare, barti wanaagsan, iska caabin heerkul hooseeya, iska caabin saliid wanaagsan, caabbinta kiimikada iyo iska caabinta deegaanka. Deganaanshaha hydrolytic ee nooca ester-ka ayaa aad uga sarreeya kan nooca polyesterka.
