特性
【基本特性】高密度聚乙烯是一种不透明白色腊状材料，比重比水轻，比重为0.941~0.960，柔软而且有韧性，但比LDPE略硬，也略能伸长，无毒，无味。
【燃烧特性】易燃，离火后能继续燃烧，火焰上端呈黄色，下端呈蓝色，燃烧时会熔融，有液体滴落，无黑烟冒出，同时，发出石蜡燃烧时发出的气味。
【主要优点】耐酸碱，耐有机溶剂，电绝缘性优良，低温时，仍能保持一定的韧性。表面硬度，拉伸强度，刚性等机械强度都高于LDPE，接近于PP，比PP韧，但表面光洁度不如PP。
【主要缺点】机械性能差，透气差，易变形，易老化，易发脆，脆性低于PP，易应力开裂，表面硬度低，易刮伤。难印刷，印刷时，需进行表面放电处理，不能电镀，表面无光泽。
【应用场合】用于挤出包装薄膜，绳索，编织袋，渔网，水管；注塑低档日用品及外壳，非承载荷构件，胶箱，周转箱；挤出吹塑容器，中空制品，瓶子。
【注塑工艺】HDPE有数不清的应用，范围从可重复使用的薄壁饮料杯到5－gsl罐，消费国内生产的HDPE的1/5。注塑品级一般熔体指数5～10，有具有韧性较低流动性品级和具有可加工性的较高流动性品级。用途包括日用品和食品薄壁包装物；有韧性、耐用的食品和涂料罐；高抗环境应力开裂应用，如小型发动机燃料箱和90－gal垃圾罐。
