Chingwe cha TPE vs chingwe cha TPU

TPE(Thermoplastic Elastomer) ndi chinthu cha Thermoplastic Elastomer (Thermoplastic Elastomer) chomwe chili ndi mphamvu zambiri, kusinthasintha kwakukulu, kupanga jakisoni, kugwiritsa ntchito mosiyanasiyana, kuteteza chilengedwe, chosakhala poizoni komanso chotetezeka, komanso utoto wabwino kwambiri.

TPU(Thermoplastic Urethane), yomwe imadziwika m'Chitchaina kuti Thermoplastic polyurethane elastomer, ndi mtundu wa TPE. TPU ndi mtundu wa zinthu zopangidwa ndi polima zopangidwa ndi diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), macromolecular polyol ndi chain extender.

Kusiyana pakati pa TPE ndi TPU:

1. Kusiyana Kwapadera kwa Mphamvu Yokoka:

TPE (0.89~1.3);

TPU (1.0~1.4);

2. Kusiyana kwa kukana mafuta

Kukana mafuta a TPE ndi kovuta, koma kumamveka bwino, kofewa komanso kosalala;

TPU ili ndi kukana mafuta bwino, kukandana kwamphamvu kwa manja komanso kusalala kofooka.

3. Kusiyana kwa kukana kutentha:

TPE (-60 ℃ ~105 ℃);

TPU (-60 ℃ ~80 ℃);

Chingwe cha WenChang TPE

4. Kusiyana kwa kulimba mtima ndi kukana kuvala:

TPU ili ndi mphamvu yolimba komanso yolimba kuposa TPE.

5. Kusiyana kwa kuuma:

TPE (0~100A);

TPU(35~90A, 50~80D), kuuma kofala kwambiri ndi 80~95A. TPU yokhala ndi kuuma kwa 50~80D siigwiritsidwa ntchito kawirikawiri. Kuuma kwa 35~75A TPU, mtengo wake ndi wapamwamba. TPU imadziwika ndi mphamvu zambiri komanso kukana kuvala bwino. Makhalidwe akuluakulu ndi awa: kuuma kwakukulu, ndipo chifukwa cha kuuma kwake, zinthu zake zimakhalabe zotanuka bwino komanso zokana kuvala bwino, mphamvu zambiri zamakanika, kukana kuzizira kwambiri, magwiridwe antchito abwino, kukana mafuta, kukana madzi, kukana nkhungu, komanso kubwezeretsanso bwino.
