1、耐磨性高居各类纯塑料，而且随分子量的增大而提高;UHMWPE与钢、铜配对时容易产生粘着磨损，对配偶件的磨损小。使用寿命高于钢质，耐磨性是炭钢及不锈钢的3～7倍;

2、自润滑性很好，滚动摩擦系数在塑料中较低，可以在无润滑下以滑动或转动的形式工作，其润滑性比钢和铜在有润滑油的情况下还要好!

3、具有很强的吸收冲击能和摩擦消音的性能，有摩擦噪声小的优点;

4、冲击强度列塑料，是现有塑料品种中较耐冲击的一种，常温冲击强度可与聚碳酸酯PC媲美，而低温冲击强度甚至比聚碳酸酯PC还要好;其冲击强度是ABS的8倍、PA66的10倍、POM的22倍、PBT的25倍!

5、耐疲劳性很好，耐疲劳强度大于50万次;

6、分子量较大，但不饱和键很少，因此具有优良的耐化学腐蚀性，能耐各类腐蚀性介质，比如：酸、碱、盐，也能耐各类有机溶剂;

7、耐环境应力开裂的性能很好，是普通乙烯的200倍，抗应力开裂时间高达4000小时;而且耐高温蠕变性也非常好;UHMWPE的耐辐射性亦很好;

8、超耐热性不高，热变形温度HD

9、电气性能良好，较佳的电绝缘性和抗静电性，体积电阻率>1015Ω.cm，介电强度为90kV/mm，介电常数2.3;

10、表面无吸附力，对任何材料都没有粘结性，具有较低的吸水率(<0.01%);

11、具有良好的抗高能辐射性;

12、无毒、无味、无渗出物;

Performance characteristics of car lining plate:
1. Impact resistance of car liner. Polyethylene car liner has large molecular weight and tight chemical bond. Therefore, it has strong impact resistance and will not break.
2. Corrosion resistance of carriage sliding plate. Polyethylene car liner is a super high molecular organic material with strong resistance to acid and alkali.
3. The car liner is not sticky, and the blanking speed is accelerated. Why not stick the material? This is because the water absorption of the high molecular weight polyethylene sheet is particularly low, and the goods will not stick to it even if the humidity is high.
4. Corrosion resistance of carriage sliding plate. Polyethylene car liner is a high molecular organic material with strong resistance to acid and alkali.
5. The car liner is wear-resistant. Polyethylene car liner has strong abrasion resistance and can be used repeatedly.
