1、机械性能

 2．热性能：

电性能：

 耐寒性

高密度聚乙烯分子量超过50万时，脆化温度降至-140℃。超高分子量聚乙烯甚至可以在液氮或液氦下作用，其使用温度可达-269以下℃，仍有一定机械强度。

 耐磨性

超高分子量聚乙烯具有极佳的耐磨性，分子量越高，材料的耐磨性越好。

超高与其他材料磨耗对比参数

注：耐磨耗性能试验条件：

沙/水=3/2(重要比) 选用16目~24目/时之间建筑用沙，试片转速800转/分，试片尽寸60mm×40mm×3mm，每个试片均磨7小时。

 超高分子量聚乙稀磨损率比较

 6．冲击强度

注:测试按ASTMD256方法进行。

 7．磨擦系数

磨擦系数是UHMW-PE具有自润滑性的原因.它可以在没有润滑油的条件下,以滑动或转动形式工作，比钢和铜在加润滑油的场合下的润滑性能还好。 

注:测试方式按ASTMD1894进行

 8..吸水率

超高分子量聚乙烯的吸水率极低，因此，其物理机械性能与使用的工况条件中的温度因素无关。

注:试验方式按ASTM570

 9.优良的耐化学腐蚀性

超高分子量聚乙烯化学稳定性很高，在一定的温度，浓度范围内能耐酸、碱、盐等各种腐蚀性介质(酸、碱、盐)及有机溶剂的作用。

 10.无毒性

超高分子量聚乙烯无味、无毒、无嗅，本身无腐蚀性，具有生理循环性和生理适应性，美国食品与药品管理局(FDA)和美国农业部(USDA)允许它用于与食品和药品接触的场合,因此适用于食品、医药等对卫生条件要求较高的行业。

 二、行业运用

因超高分子量聚乙烯这种性能优良的热塑性工程塑料，其制成品板材在不同领域得到广泛的运用

料仓、溜槽衬里

在贮仓、料箱、料斗或其它容器的散装物料以及这些物料在溜槽、漏斗、输送溜槽和相类似设备的贮存和运输过程中，通常由于物料结块、架桥或冻结而受阻，解决这些问题耗资费时。采用超高分子量聚乙烯材料衬里是解决这些问题的最佳形式。因为用超高分子量聚烯材料衬里具有如下优点：

高耐磨和极低磨擦系数，防止物料架桥时流动受阻；

极低吸水性。它不被水所润湿，不受物料湿度的影响。因此，物料不会在衬里壁上，或特别是露天作业，也不会因温度太低造成湿的物料和容器冻在一起；

符合卫生标准。超高分子量聚乙烯为无味、无嗅、无毒的材料。因此，允许用于与食品和药品接触的场合。

　衬里的应用事例

    2．码头护弦板

本产品作为码头护弦板，可防止船舶与码头的撞击而造成的损坏，具有良好的抗冲击性能，替代传统的钢制护弦，有单独作护弦板，有橡胶复合，广泛运用各大港口，国内外港口均采用些方案，根我们了解，做橡胶护弦的单位，一年，每家单位PE/UHMPE 板一年的用量有两三百万，市场较为乐观。

3．一般机械用各类导槽、导轨、导流板等

4．农业机械和建筑机械：

利用超高分子聚乙烯量的自润滑性、不粘性，在日本和欧州广泛用于农耕机械和推土机的推土板、汽车翻斗衬里。这样可使其不与泥土、泥浆等粘连，以此节约能耗，提高作业效率。

5．运动及娱乐器材：滑雪具衬里。

6．砧板：食品加工厂用的切配台板、工作台面等

 应用领域： 可广泛应用于采矿业、选煤厂、冶金工业、热电厂、造船业等部门的输送液体、固体、固液混合体的漏斗、漏槽、翻板、刮板输送机的滑道、跳汰机筛板、浮选机衬板、船舶货舱内衬板、大型滑块、矿车、翻斗车车厢衬里等的耐磨耐腐应用，具有物超所值的独特优势。
