~Identification:
Chemical Name: Diethyl Ethyl Phosphonate
Synonyms: Flame Retardant DEEP
CAS NO.:78-38-6
Molecular formula: C6H15O3P   

Introduction and Application
Flame retardant DEEP is a new highly 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 1.5-2 times of TCPP, DEEP is low viscosity, do not contain halogen, the chemical stability is very good in the in the polyether diverse alcohols and isocyanate two-component system. At the same time it is with efficiently reduced viscosity, improve water foaming hard bubble and the operation in rigid polyurethane foam system. The dosage of DEEP can be as high as 20-25, accord with  flame retardant standard B2.  It doesn't fit in with isocyanate components, prepolymer and mono-foam plastic.
