Polyurethane ndiyo TPU ari Thermo Plastic Urethane pfupi, Chinese anonzi: thermoplastic polyurethane elastomer, TPU ari diphenylmethane diisocyanate, toluene diisocyanate, uye macromolecular polyol, chain extender vakaita pamwe polymer nezvinhu polymerized kubva . samolecular mamiriro ayo rinoumbwa diphenylmethane diisocyanate, toluene diisocyanate uye cheni extender kupa yakaoma nechigumbuso uye diphenylmethane diisocyanate, toluene diisocyanate, uye macromolecular polyols vakawana nyoro chidimbu rakatumbuka configuration.

Kandira simbi polyurethane bhegiCastersRine zvinotevera zvazvakanakira:

1 ane kwazvo mukuru tensile simba, mukuru tensile simba, kusimba uye kuramba kukwegura, ane ruzivo zvakatipoteredza ushamwari zvinhu.

2. mamwe epurasitiki zvinhu kuva mukuru simba usingagoni kuenderana, kuoma zvakanaka, abrasion nemishonga, mafuta nemishonga, mvura nemishonga, kuchembera nemishonga,

Panguva iyoyo ine unyoro-permeable yakakwirira isapinda pfuma, zvinhu zvakawanda kwazvo antibacterial, antifungal, Anti UV simba kusunungurwa uye zvakafanana.
