Diethyl Ethylphosphonate Flame Retardant

lame retardant DEEP is a high efficient organic phosphorous flame retardant, it can be widely added in a variety of rigid polyurethane foam, including rigid foam recipe in all kinds of foam system. Its flame retardant efficiency is 1.5-2times of  TCPP. DEEP is low viscosity, halogen-free, the chemical stability is very good in polyether amine, polyols or alcohols and isocyanate two-component system. At the same time, it efficiently reduces viscosity, improve water foaming hard bubble and the operation in rigid polyurethane foam system. 20-25% DEEP in polymer system will meet flame B1 and B2 retardant standard.
