Polyether/TDI type prepolymer

The products have good wear resistance, water resistance, mold resistance, excellent mechanical properties, and color can be added to adjust the color. It is used to make polyurethane products such as rubber stick, rubber wheel, plate, rubber coating and miscellaneous parts.
