  • 專業解析

    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:


    一、核心特性

    1. 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)。

    2. 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。

    3. 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。

    4. 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)。

    5. 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。


    二、關鍵應用領域


    三、安全與環保認證

    HDPE被美國食品藥品監督管理局(FDA)及歐盟委員會(EC)No 10/2011列為食品接觸安全材料,且不含雙酚A(BPA)。其生命周期評估(LCA)顯示,再生HDPE(rHDPE)可減少75%的碳排放,推動綠色制造轉型。

    網絡擴展資料

    High Density Polyethylene(簡稱HDPE),中文譯為高密度聚乙烯,是一種由乙烯單體通過聚合反應形成的熱塑性合成樹脂。以下是其詳細解析:


    定義與基本性質

    1. 化學組成
      HDPE屬于聚乙烯(Polyethylene, PE)家族,分子結構呈線性排列且支鍊少,因此具有較高的結晶度(約80-90%)。其密度範圍為0.941-0.960 g/cm³,顯著高于低密度聚乙烯(LDPE)。

    2. 物理特性

      • 外觀:通常為白色粉末或顆粒狀。
      • 耐熱性:軟化點為125-135℃,最高使用溫度可達100℃。
      • 機械性能:硬度高、抗拉伸性強、耐蠕變性優異,且抗沖擊性能良好。

    主要應用領域

    HDPE因耐化學腐蝕、輕質且耐用的特點,廣泛用于以下領域:


    與其他聚乙烯的對比

    HDPE與低密度聚乙烯(LDPE)的主要區别在于分子結構:
