Polymer heat resistance
WebAn epoxy resin system and epoxy resin technology, applied in the field of polymer materials, can solve the problems of destroying electrical properties, heat resistance and reliability of use, flame retardants cannot participate in the curing reaction of resin systems, and limited application range. Achieve uniform stability, high toughness, and good heat resistance WebCompared with VER sample, the peak heat release rate (PHRR) and total heat release (THR) of the P/N-containing VER sample were reduced by 55.6% and 44.0%, respectively. The improved flame retardancy was mainly due to the suppressed burning reaction in the gas phase and improved carbonization capacity in the condensed phase.
