Abstract Halogen-free flame retardant polyolefin materials represented by magnesium hydroxide flame retardant have been playing an important role in the flame retardant field because of their non-toxic and eco-friendly characteristics. In view of its high addition result from its low flame retardant efficiency determined by the flame retardant mechanism and the large number of solid phase products left after decomposition, more resi-dual char of its composites will be left after combustion, which provides material basis for the ceramization. However, the ceramifiable flame retardant polyolefin materials based on magnesium hydroxide have been less studied. Polymer ceramic precursor materials—polycarbosilane, has high ceramic yield, which is often used to produce ceramic components with complex structures, but its application in flame retardant of polyolefin is rarely reported. In this paper, flame-retardant polyethylene (PE) composites were prepared with polycarbosilane and magnesium hydroxide, the effect of polycarbosilane on the structure of condensed char layer of the composites was studied. The results show that polycarbosilane can effectively bond magnesium oxide particles together and produce a ceramic carbon layer with special structure.
