Abstract:In this work, we investigated polymer compositions based on epoxy resin cured with polyethylene polyamine and containing ammonium polyphosphate and boric acid as a blowing agent and carbonization stimulator. The UL 94 method was used to determine the ability of a material to burn or extinguish after flame treatment. We determined the ability of the material to burn or extinguish when exposed to a gas burner. Weight loss at characteristic temperatures was determined using a Perkin Elmer STA8000 synchronous DTA … Show more
