Graphite polystyrene (SEPS) board, the full name is graphite molded polystyrene foam board for insulation, commonly known as "black foam" or "blackboard", referred to as SEPS. It is a new type of polystyrene insulation board and a highly flame-retardant polystyrene insulation material developed by BASF of Germany. Its production process is to add 5%-50% by mass of expanded graphite and 2%-20% of phosphoric acid compounds as flame retardants to expandable polystyrene (EPS), and prepare expanded PS particles by suspension polymerization. Graphite is introduced into expandable polystyrene (EPS) to make it have better flame retardant properties while maintaining excellent thermal insulation properties. At present, the country is promoting the introduction of national standards for SEPS boards, which will be extremely beneficial to the market promotion of highly flame-retardant SEPS insulation boards.
