聚苯乙烯泡沫是一種輕型高分子聚合物。它是采用聚苯乙烯樹脂加入發(fā)泡劑,同時加熱進行軟化，產(chǎn)生氣體,形成一種硬質(zhì)閉孔結(jié)構(gòu)的泡沫塑料。泡沫芯材的機制板重量輕,表面平整。但不耐高溫,怕明火

Polystyrene foam is a light polymer. It is a foamed plastic which is addedwith a foaming agent by using a polystyrene resin and softened at thesame time to generate a gas to form a hard closed cell structure. Themechanism board of the foam core material is light in weight and flat on thesurface. But it is not resistant to high temperatures, and should be keptaway from open flames
