Study on the Hyperbranched Polyphosphate Ester Modified Epoxy Resin

Article Preview

Abstract:

Mechanical properties and flame retardant property of the cured epoxy resins contained different content of hyperbranched polyphosphate ester(HPPE) were studyed. The results indicated that the tensile strength and the impact strength were inceased to11.26% and 306% respectively with HPPE loadings of 15%,besides the Oxygen Index(OI) value increased from 22 to 33 which shows a good flame retardant property was obtained.
