DTY-303 premixed polyether polyols
Introduction
DTY-303 premixed polyether polyols is mainly designed by targeting at the whole water system and has been widely used in the solar water heater and split-type solar thermal insulation layer. This system shows excellent stability, operability, liquidity and thermal insulation property. When this premixed polyether polyols hereof is reacting with polymerized PM-2010 or PM-200, the prepared foam shows even density distribution and even distribution of heat conductivity coefficient as well as high compression strength, high bonding strength and high dimensional stability.
