高密度聚乙烯(High-Density Polyethylene,简称HDPE)是一种由乙烯单体聚合而成的热塑性塑料,属于聚烯烃家族的重要成员。其分子结构主要为线性排列,分子链分支少,结晶度高(通常达80%-90%),因此具备以下核心特性与应用价值:
高密度与刚性
密度范围在0.93–0.97 g/cm³,高于低密度聚乙烯(LDPE),赋予其优异的抗压强度和刚性,适用于承重场景(如货架、工业容器)。
耐化学腐蚀性
对大多数酸、碱、有机溶剂(如酒精、清洁剂)具有极强抵抗力,广泛用于化学储罐、实验室器材及管道系统。
低吸湿性与防渗透性
几乎不吸水(吸水率<0.01%),且对水蒸气、气体的阻隔性能优异,是食品包装(如牛奶瓶)、防水材料的理想选择。
耐低温与抗冲击性
在-50°C至+90°C环境下保持韧性,抗环境应力开裂(ESCR)性能突出,适用于冷藏包装、户外设施(如防冻管道)。
可回收性
回收代码为“2”,可通过熔融再造粒重复利用,符合循环经济要求。
