COPOLYMER POLYOL LY-2015
General Properties and Applications
LY-2015 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-2015 results from the addition of propylene oxide and ethylene oxide to glycerin, under base catalysis.
