有防滑槽和提手的悬臂梁垫块

分子量聚乙烯重型机械车工程车支腿垫板比普通的支腿垫板抗压能力更强，更耐磨，使用寿命更长，既节约了成本，又提高了使用效率
一、耐磨性 UHMWPE的耐磨性居塑料之冠，并超过某些金属，UHMWPE的砂浆磨耗指数仅是 PA66的1/5，HDPE和 PVC的1/10；与金属相比，是碳钢的1/7，黄铜的l/27。
二、耐冲击性 UHMWPE的冲击强度约为耐冲击PC的2倍，ABS的5倍，POM和PBTP的10余倍。
三、自润滑性 UHMWPE有极低的磨擦系数(0.05～0.11)，自润滑性。在无润滑剂的条件下仅次于自润滑性好的；当它以滑动或转动形式工作时，比钢和黄铜添加润滑油的润滑性还要好。
四、耐化学药品性 UHMWPE具有优良的耐化学药品性，除强氟化性酸液外，在一定温度和浓度范围内能耐腐蚀介质（酸、碱、盐）及有机介质（萘溶剂除外）。
五、冲击能吸收性 UHMWPE具有的冲击能吸收性，冲击能吸收值在所有塑料中高，因而噪声阻尼性很好，具有优良的消音效果。
六、不粘性 UHMWPE表面吸咐力非常微弱，其抗粘附能力仅次于塑料中不粘性好的PTEE，因而制品表面与其它材料不易粘附。
七、憎水性 UHMWPE吸水率很低，一般小于0.01%，仅为 PA6的1%。
Ultra high molecular weight polyethylene heavy duty mechanical vehicle engineering vehicle support leg pad has stronger compressive resistance, more wear resistance and longer service life than the ordinary support leg cushion. It saves cost and improves the efficiency of use.

First, the wear resistance of UHMWPE is the highest in plastics, and the wear index of mortar is only 1 / 10 of that of PA66 and PVC. Compared with metal, it is 1 / 7 of carbon steel and 1 / 27 of brass.

Secondly, the impact strength of impact resistant UHMWPE is about 2 times of that of PC and 5 times of that of PBTP and more than 10 times of that of PBTP.

Third, the self-lubricating UHMWPE has a very low friction coefficient of 0. 05 ~ 0. 11% and excellent self-lubricity.When it works in sliding or rotating form, it is better than that of steel and brass when lubricating oil is added under the condition of no lubricant, which is second only to the best self-lubricating property of PTFE (polytetrachloroethylene-tetrachloroethylene-tetrachloroethylene).

(4) Chemical resistant UHMWPE has excellent chemical resistance, except for strong fluorinated acid, corrosion resistant medium (acid, alkali, salt) and organic medium (naphthalene solvent except naphthalene) can be corroded in certain temperature and concentration range.

Fifth, the impact energy absorbability UHMWPE has excellent impact energy absorbability, the impact energy absorption value is the highest among all plastics, therefore the noise damping property is very good, has the excellent silencing effect.

Sixthly, the adsorption force on the non-viscous UHMWPE surface is very weak, and its anti-adhesion ability is second only to that of the non-adhesive UHMWPE in plastics, so it is not easy to adhere to the surface of the product with other materials.

Seventh, the water absorption of hydrophobic UHMWPE is very low, generally less than 0.01, which is only 1% of PA6.
