Trademark	Hydroxyl value mgKOH/g	Acid value mgKOH/g	Water content %	pH	Unsaturated value mol/kg	Viscosity mPa·s/25℃	K+ mg/kg	Colourity APHA	Application	Feature
DL-400	270-290	≤0.05	≤0.05	5-7	-	60-80	≤5	≤50	This is a diol polyether with a molecular weight of 400. It can be used for a variety of pavement polyurethane products with a higher toughness.	DL series products are mainly used for CASE series products, with a molecular weight range from 700 to 12000. For application, as the molecular weight of the polyol increases, the elongation at break gradually increases while the tensile strength and hardness decreases. Customers may choose polyether polyols of different molecular weight according to their final product’s request. They can also arrange MN-3050DF, EP-330NG or EP-3600 in groups to increase the product’s tensile strength.
