1. Wear resistance of ultra-high molecular weight polyethylene UHMW-PE is the highest in all kinds of pure plastic first, and with the molecular weight increase and improve; prone to adhesive wear of UHMWPE with steel, copper paired spouse pieces wear. Service life than steel, carbon steel and stainless steel 3 to 7 times the abrasion resistance; ultra-high molecular weight polyethylene UHMW-PE good self-lubricating, rolling friction coefficient in plastic in the lowest, in the non-lubricated under the form of sliding or rotation of the work, its lubricating properties than steel and copper in the lubricating oil is also good! Ultra-high molecular weight polyethylene UHMW-PE has a strong absorption of the red skills and friction silencing have small friction noise; 4. Impact strength of ultra high molecular weight polyethylene UHMW-PE column plastic first, the current the impact resistance of a plastic varieties most room temperature impact strength comparable with polycarbonate PC, while the low-temperature impact strength or even better than the polycarbonate PC; 8 times the impact strength of ABS, PA66 10 times, POM 22 times, PBT 25 times! 5. Ultrahigh molecular weight polyethylene UHMW-PE fatigue resistance of the well, the fatigue strength is greater than 50 million times; 6 The molecular weight of the ultrahigh molecular weight polyethylene UHMW-PE greatly, but rarely unsaturated bond and therefore have excellent chemical resistance, the ability of the various kinds of corrosive media, such as: acid, alkali, salt, and also the ability of various organic solvents; 7 ultra-high molecular weight polyethylene UHMW-PE resistance to environmental stress cracking performance is very good, ordinary 200 times that of ethylene, resistance to stress cracking time up to 4000 hours; and high temperature creep resistance is also very good; UHMWPE radiation resistance is also very good; 8 ultra-high molecular weight polyethylene UHMW-PE is not high heat resistance, heat distortion temperature HDT of 90 ° C, the use of a temperature of 100 to 110 ℃; very good low temperature resistance, can be as low as -169 ° C, the best plastic varieties, low temperature resistance and good low temperature impact resistance; 9 ultra-high molecular weight polyethylene ethylene UHMW-PE good electrical properties, excellent electrical insulating properties, and antistatic properties, the volume resistivity> 1015Ω. cm, dielectric strength of 90kV/mm, dielectric constant of 2.3; 10. the surface of the ultrahigh molecular weight polyethylene UHMW-PE no suction force, there is no adhesion to any material, having a very low water absorption (<0.01%) ; 11 ultra-high molecular weight polyethylene UHMW-PE has good resistance to high-energy radiation; 12 ultra-high molecular weight polyethylene UHMW-PE non-toxic, tasteless, non-exudate; 13 ultra-high molecular weight polyethylene UHMW-PE resistance Aging excellent anti-aging properties, under natural sunlight conditions, the aging life of ultra-high molecular weight polyethylene for 50 years; 14 ultra-high molecular weight polyethylene UHMW-PE has excellent machining properties.
