摘要

As a toughening agent, poly(ehtene-co-octene) elastomer (POE) could raise the notched impact strength of polypropylene(PP), especially in low temperatures. Eth-ylene-octene/ polypropylene blends were widely used in many domains. An Intumescent flame retardant and SiO_2 were introduced into ethylene-octene/polypropylene blends as flame retardant and its synergistic agent. The flame retardancy of the new system was estimated with the UL94 tests, cone calorimeter test, of which contained heat release rate test and smoke release rate test, and Thermogravimetric property was also investigated. According to the results of flammability tests, the SiO_2 showed synergistic effect apparently when its content reached l%(weight percent of the whole system, the same below).
