塑料泡沫(即聚苯乙烯泡沫)具有良好的减震性和优良的隔热保温性能,所以不仅广泛用来做包装,还用来做太阳能外壳、保鲜盒及冰箱隔层等保温隔热产品。由于塑料泡沫的普遍应用,而且强度低、易损坏,又多是一次性用品,所以其废弃物的数量急剧增加,长期不腐烂,已对人类生存环境构成长 Plastic foam (ie, polystyrene foam) has good shock absorption and excellent thermal insulation properties, it is not only widely used in packaging, but also used to make solar enclosures, crisper and refrigerator insulation and other insulation products. Due to the widespread application of plastic foam, but also low strength, easy to damage, but also more disposable supplies, so the sharp increase in the number of waste, long-term non-decay, has constituted a long human living environment
