Polyurethane o TPU o se puupuu Urethane palasitika Thermo, ua taʻua o Saina: thermoplastic elastomer polyurethane, TPU o se diisocyanate diphenylmethane, diisocyanate toluene, ma polyol macromolecular, na tali extender filifili mea polymer faatasi polymerized mai . O lona fausaga molecular e aofia ai diisocyanate diphenylmethane, toluene diisocyanate ma se filifili extender e tuuina atu se poloka maumaututū ma a diisocyanate diphenylmethane, toluene diisocyanate, ma maua polyols macromolecular configuration alternating vaega filemu.

taga polyurethane uʻamea lafoCastersO loo i ai le tulaga lelei o nei:

1 le malosi ua sili ona lelei tensile maualuga, malosi maualuga tensile, maʻaʻa ma tetee atu i le soifua matua, o se mea siosiomaga faauo matutua.

2. isi palasitika mea ua i ai se maualuga e mafai e le tutusa le malosi, maʻaʻa lelei, tetee abrasion, tetee suauu, vai tetee, matutua tetee,

I le taimi lava e tasi o loo i ai se susu-permeable maualuga meatotino susu, o le tele o vaega e sili ona lelei antibacterial, antifungal, aneti-UV faamatuu atu le malosi ma le e pei o.
