石墨聚苯板也称B1级石墨聚苯板，俗称“黑泡沫”或“黑板”，简称SEPS，它全称为B1级石墨模塑聚苯乙烯泡沫板。石墨聚苯板的性能：密度：18-25kg/m³，导热系数：≤0.032；燃烧性能：分级达B1（难燃）；保温性、经济性、耐热性、抗湿度性能强，属于绿色环保产品，广泛应用于建筑内、外墙保温系统，尤其是有防火要求而需采用B1级聚苯板的外墙保温工程。
SEPS ,namely B1 grade graphite polystyrene
board, commonly known as "black foam" or "blackboard",
referred to Graphite polystyrene board. its full name is the B1 graphite molded
polystyrene foam board. The performance of graphite polystyrene board: density:
18-25kg/m; heat conduction system: ≤0.032; combustion performance: classified
as B1 (flame retardant);its thermal insulation, economy, heat resistance,
humidity resistance performance is strong and belongs to the green
environmental protection products, and is widely used in the construction of
internal and external wall insulation system, especially the polystyrene board
insulation engineering with the fire prevention requirements of B1.
