Abstract: The ceramifiable EPDM composite was prepared using glass powder, mica powder and montmorillonite as ceramic filler. The effects of ceramic fillers on the structure and properties of composites and their sintered ceramics were investigated by means of limiting oxygen index, vertical combustion, electronic universal testing machine and scanning electron microscope. The results show that the ceramic filler can improve the flame retardant and mechanical properties of the composite to a certain extent. Moreover, the content of the glass powder and sintering temperature can effectively improve the integrity and mechanical properties of the ceramic.
