Polyurethane ni TPU ni Thermo plastiki Urethane short, Kichina inaitwa: thermoplastic polyurethane elastomer, TPU ni diphenylmethane diisosianati, Toluini diisosianati, na macromolecular polyol, mnyororo extender ilijibu vifaa pamoja polymer polymerized kutoka . muundo wake Masi kinaundwa diphenylmethane diisosianati, Toluini diisosianati na extender mlolongo wa kutoa block rigid na diphenylmethane diisosianati, Toluini diisosianati, na polyols macromolecular kupatikana laini sehemu alternating usanidi.

Kutupwa chuma polyurethane mfukoCastersIna faida zifuatazo:

1 ina bora high tensile nguvu, high tensile nguvu, ushupavu na upinzani dhidi ya kuzeeka, ni kukomaa vifaa rafiki wa mazingira.

2. vifaa vingine vya plastiki kuwa nguvu ya juu hawezi mechi, ushupavu nzuri, abrasion upinzani, upinzani mafuta, maji upinzani, kuzeeka upinzani,

Wakati huo huo, ina high unyevu-permeable waterproof mali, sifa nyingi nzuri antibacterial, antifungal, kupambana na UV nishati kutolewa na kadhalika.
