Yini i-tPU?

I-Thermoplastic Polyurethane (TPU) isigaba esiyingqayizivele seplastiki esenziwe lapho ukusabela kwe-polyaddition kwenzeka phakathi kwe-diisocyanate kanye ne-diols eyodwa noma ngaphezulu. First developed in 1937, this versatile polymer is soft and processable when heated, hard when cooled and capable of being reprocessed multiple times without losing structural integrity. Isetshenziswe njengeplastiki yobunjiniyela obungenamkhawulo noma esikhundleni senjoloba kanzima, i-TPU idume ngezinto eziningi kufaka phakathi kwayo: ukugcwala okuphezulu kanye namandla ashubile; ukuqina kwalo; Futhi emagcekeni ahlukahlukene, amandla ayo okumelana namafutha, amafutha, ama-solvents, amakhemikhali kanye ne-abrasion. Lezi zici zenza i-TPU ithandwe kakhulu ngaphesheya kwezimakethe nezinhlelo zokusebenza. Iguquguqukayo ngokwemvelo, ingakhishwa noma i-injection yabumba imishini yokukhiqiza ye-thermoplastic ukudala izingxenye eziqinile zezinyawo, ikhebula kanye ne-tube, ifilimu kanye neshidi noma eminye imikhiqizo yezimboni. Kungahlanganiswa futhi ukudala ukubumba okuqinile kweplastiki noma kusetshenzwe kusetshenziswa izilonge ze-organic ukwakha izindwangu ezihlanjululwe, izimbotshana ezivikelayo noma izinamathiseli ezisebenzayo.
