泡沫机制板

聚苯乙烯泡沫是一种轻型高分子聚合物。它是采用聚苯乙烯树脂加入发泡剂,同时加热进行软化，产生气体,形成一种硬质闭孔结构的泡沫塑料。泡沫芯材的机制板重量轻,表面平整。但不耐高温,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
