Prepolymer na uri ng polyether/TDI
Ang mga produkto ay may magandang wear resistance, water resistance, mold resistance, mahusay na mekanikal na katangian, at kulay ay maaaring idagdag upang ayusin ang kulay.Ito ay ginagamit upang gumawa ng mga produktong polyurethane tulad ng rubber stick, rubber wheel, plate, rubber coating at iba't ibang bahagi.
