POLYURETHANE FOAMS WITH IMPROVED INSULATION RESISTANCE AND POLYURETHANE FOAMS HAVING IMPROVED RETENTION OF INSULATIVE PROPERTIES AND METHODS FOR THE PREPARATION THEREOF

摘要

A polyurethane foam having improved insulating retaining properties can be produced. The foams may contain glycerin-initiated ethoxylated polyols prepared from formulations containing from 2 to 3 moles of ethylene oxide per mole of glycerin initiator and / or from 2 to 15 moles of ethylene carbonate per mole of initiator, wherein the molar ratio of ethylene carbonate to functionality of the initiator is from 0.5 to less than 2 RTI ID = 0.0 polyoxyalkylene /RTI polyol as disclosed herein.
