UHMW-PE特点为：极好的耐磨性，良好的耐低温冲击性、自润滑性、耐水、耐化学药品性，耐热性优于一般PE。 UHMW-PE的用途：可以代替碳钢、不锈钢、青铜等材料用于纺织、造纸、食品机械、运 输、医疗、煤矿、化工等部门 。如纺织工业上技梭器、打梭棒、齿轮、联结 、扫花杆、缓冲块、偏心块、杆轴套、摆动后果等耐冲击磨损零件。造纸工业上做箱盖板、刮水板、压密部件、接头、传动机械的密封轴杆、偏导轮、刮刀、过滤器等；运输工业上做粉状材料的料斗、料仓、滑槽的衬里。UHMW-PE可做各种机械的零部件，包括食品机械的齿轮、蜗轮、蜗杆、轴承。化工中做泵、阀门、档板、滤板。医疗上，还可用于心脏瓣膜、短形外科零件，人工关节及节育植入体。体育上做滑冰地板、滚地球道、滑雪板、机动雪橇零件。
UHMW- PE可以做高模量纤维，制造防弹衣、飞机座椅、海运、渔业用绳索等。 为何应用PE：PE 生产原材料是现有聚合物中佼佼者。超高分子量聚乙烯帮助生产商节省了由于设备检修以及待料造成的停工，改良了设备运行，减少了润滑油的需量，并且取代了相应的钢质部件，从而节省了运行成本。其食品级可靠、快捷方便、无需防腐、省工省力，充分体现出使用超高分子量聚乙烯产品“节能、环保、经济”的优越性。此材料的应用给广大用户带来更好的经济效益和社会效益。High Density is commonly used for milk jugs and food containers. Low Density is commonly used for bottles and plastic bags. UHMW, which has higher molecular weight (2-6 million) allows for an even transfer over the length of material which makes it stronger and able to be used for bearing applications due to its great wear resistance. Commonly used in the food and dairy industry, UHMW is a great replacement for other materials and solution to many problems. All of these polymers are derived from the same family but all have certain properties that make them a little different. HDPE provides great chemical resistance, with high impact strength and great energy absorption. LDPE has most of the same properties as High Density but is not as dense at 9.15, opposed to HDPE which is 9.34. It also has a lower tensile strength and easier formability.
