石墨聚苯板也稱B1級石墨聚苯板,俗稱“黑泡沫”或“黑板”,簡稱SEPS,它全稱為B1級石墨模塑聚苯乙烯泡沫板。石墨聚苯板的性能:密度:18-25kg/m3,導(dǎo)熱系數(shù):≤0.032;燃燒性能:分級達B1(難燃);保溫性、經(jīng)濟性、耐熱性、抗?jié)穸刃阅軓?,屬于綠色環(huán)保產(chǎn)品,廣泛應(yīng)用于建筑內(nèi)、外墻保溫系統(tǒng),尤其是有防火要求而需采用B1級聚苯板的外墻保溫工程。
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.
