Abstract

In this paper, we formulate an intumescent flame-retardant system (FR-NP) using piperazine pyrophosphate (PPAP) and melamine polyphosphate (MPP) as the principal components, in conjunction with a self-manufactured surface modifier. The flame-retardant performance, mechanical properties and weather resistance of this system in polypropylene (PP) were investigated. Our experimental findings suggest that incorporating 24% FR-NP into polypropylene yields a V-0 flame-retardant rating. In weathering tests, no white spot precipitation was observed in dark-coloured polypropylene materials.
