COPOLYMER POLYOL LY-2010
General Properties and Applications
LY-2010 polyether polyol is a tri-functional polyether polyol, which contains primary hydroxyl groups, have a high rate of reactivity with isocyanates. It contains an antioxidant which is free from BHT ((2, 6-Di-t-butyl-hydroxytoluene).
LY-2010 results from the addition of propylene oxide and ethylene oxide to glycerin, under base catalysis.

Handling Precautions
Flash point is above 200ºC(open cup method),flammable but non-explosive. In case of fire, put out with
foams, dry powder, steam or water.
