HDPE Roller/Idler UHMWPE Rollers for mining

UHMW PE is short for Ultra High Molecular Weight Polyethylene,molecular weight range from 1.5 million to 6 million. UHMWPE gets the highest score in following six features among all plastic material : The highest wear-resistance , The highest impact resistance, The highest corrosion resistance, The highest self-lubricating and The highest absorbing impact. UHMWPE has following advantages: 1、Resistance and durability to impact,friction,corrosion and chemicals These features enable UHM PE have various application fields. 2、Light weight The gravity of UHMWPE is 0.95 ,lighter than water,amount to steel’s 1/7. In cost view,UHMWPE is steel’s 1/3 in per cubic inch.In addition it’s low cost in maintenance, which makes the UHMWPE more economical and practical .easy to processing ,such as polishing,drilling and cutting ,and so on. 3 、 Wear-resistance ： UHMWPE 's wear-resistance grasp the NO.1 place in plastic field. For example, on Slurry abrasion index, UHMWPE is 1/10 of carbon steel, 1/27 of brass. 4 、 Self-lubricating UHMWPE has low friction coefficient (0.05-0.11), so it has excellent self-lubricating property, its smoothness remiss the damage brought by friction heat.so it is easy to maintenance .better than lube. 5 、 Low noise UHMWPE damping property is the best in plastic, as well as noise damping 6 、 Electric insulation: UHMWPE has a feature of high resistivity, so it has good performance in insulation, especially in coal mine 7 、 Anti corrosion and chemical resistant UHMWPE has excellent anti-corrosive feature and chemical resistant. Expect strong oxidant acid solution, UHMWPE can resist any corrosive medium (acid, alkali and salt) and organic medium (except Naphthalene solvent) at certain temperature and concentration It surface don't have any abnormal-ism and physical properties have no change. 8 、 Hydrophobicity UHMWPE has low water absorption, ＜ 0.01% ， so it don't change its shape in water
