高密度聚乙烯(High-Density Polyethylene,簡稱HDPE)是一種由乙烯單體聚合而成的熱塑性塑料,屬于聚烯烴家族的重要成員。其分子結構主要為線性排列,分子鍊分支少,結晶度高(通常達80%-90%),因此具備以下核心特性與應用價值:
高密度與剛性
密度範圍在0.93–0.97 g/cm³,高于低密度聚乙烯(LDPE),賦予其優異的抗壓強度和剛性,適用于承重場景(如貨架、工業容器)。
耐化學腐蝕性
對大多數酸、堿、有機溶劑(如酒精、清潔劑)具有極強抵抗力,廣泛用于化學儲罐、實驗室器材及管道系統。
低吸濕性與防滲透性
幾乎不吸水(吸水率<0.01%),且對水蒸氣、氣體的阻隔性能優異,是食品包裝(如牛奶瓶)、防水材料的理想選擇。
耐低溫與抗沖擊性
在-50°C至+90°C環境下保持韌性,抗環境應力開裂(ESCR)性能突出,適用于冷藏包裝、戶外設施(如防凍管道)。
可回收性
回收代碼為“2”,可通過熔融再造粒重複利用,符合循環經濟要求。
