摘要：NOVELTY - Use of halogen free phosphorus-containing flame retardant having 3-7 wt.% of phosphorus, 300-1000 g/mole of molecular weight, a functionality of 2-6 and a hydroxyl terminal group, for polyurethane foam, is claimed. USE - The halogen free phosphorus-containing flame retardant is useful for polyurethane foam, polyurethane elastomer and polyurethane synthetic leather (claimed). ADVANTAGE - The halogen free phosphorus-containing flame retardant has good compatibility, increases the flame retardant property of the product without deterioration, and provides the polyurethane foam with density of 31 kg/m3, improved compression strength, high temperature dimensional stability and oxygen index value of 19.2-23.9%.
