高密度聚乙烯（HDPE），为白色粉末或颗粒状产品。 无毒，无味，结晶度为80%～90%，软化点为125～135℃，使用温度可达100℃；硬度、拉伸强度和蠕变性优于 低密度聚乙烯；耐磨性、电绝缘性、韧性及耐寒性较好； 化学稳定性 好，在室温条件下，不溶于任何有机溶剂，耐酸、碱和各种盐类的腐蚀；薄膜对水蒸气和空气的渗透性小，吸水性低；耐老化性能差，耐环境应力开裂性不如低密度聚乙烯，特别是热氧化作用会使其性能下降，所以树脂中须加入抗氧剂和 紫外线吸 …

With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code. In 2008, the global HDPE market reached a volume of more than 30 million tons. [2]

HDPE plastic is a polyethylene thermoplastic created from petroleum. Also known as alkathene or polythene when used for pipes, HDPE is commonly used to produce items like cutting boards and plastic bottles.

High-Density Polyethylene (HDPE) is a type of plastic polymer made from petroleum. It is known for its high strength-to-density ratio and is widely used in various applications, including packaging, containers, pipes, and plastic lumber.

High Density Poly Ethylene (HDPE) is a thermoplastic polymer made from petroleum. As one of the most versatile plastic materials around, HDPE plastic is used in a wide variety of applications, including plastic bottles, milk jugs, shampoo bottles, bleach bottles, cutting boards, and piping.

HDPE is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and a small amount of α-olefin monomer. HDPE is synthesized under low pressure and is therefore also called low-pressure polyethylene. HDPE is mainly a linear molecular structure and has little branching. It has a high
