ʻāpana:Aia ʻo DY2513 e nā ʻāpana ABC.ʻO ka mea A he polyol, ʻo B ka polyurethane prepolymer i hoʻopau ʻia me ka isocynate, ʻo C ka mea hoʻonui kaulahao.
ʻano:ʻO ka huahana hope loa e hauʻoli i ka hiki ke kū'ē kū'ē maikaʻi, ka rebound maikaʻi.A hiki ke hoʻololi i ka paʻakikī e ka ratio like ʻole.Hiki ke hoʻololi ʻia ke kala e ka pigment.
Noi:Ua hoʻohana ʻia kēia mea no ka hana ʻana i nā kānana Polyurethane, nā wili PU, nā puaʻa hoʻomaʻemaʻe (discs) a me nā elastomer ʻē aʻe.
