Ultrahigh molecular weight polyethylene (UHMWPE) UHMWPE bar bar (white): English name of Ultra-high molecular weight polyethylene (also known as UHMW-PE), is a molecular weight greater than 1.5 million engineering thermoplastics. Having a molecular chain length is 10 to 20 times the high-density polyethylene, a longer molecular chain (higher molecular weight) given that the main advantage of UHMWPE toughness, wear resistance and resistance to stress cracking resistance, because it is one of polyethylene species, UHMWPE also has lubricating properties, chemical resistance and excellent electrical properties and versatility HDPE, and its successful development is generally considered one of the top ten scientific and technological achievements of the 20th century. Features: excellent wear resistance and good low temperature impact resistance, self-lubricating, non-toxic, water resistance, chemical resistance, heat resistance than the general PE, disadvantage is that heat resistance (heat distortion temperature) Low , poor molding, the outer surface hardness, rigidity, creep resistance is generally inferior to plastic expansion coefficient is too large. UHMWPE poor mobility, high viscosity of the molten state, is in the form of a highly viscous rubber-like elastomer, can only be used early pressing and sintering molding, it is also available for extrusion, injection molding and blow molding processing methods. Mechanical performance than the usual high-density polyethylene. Has outstanding impact resistance, stress cracking resistance, high temperature creep resistance, low coefficient of friction, self-lubricating, excellent chemical resistance, fatigue resistance, noise damping resistance, radiation resistance. Temperature 100 ~ 110 ℃. Cold is good, it can be used at -269 ℃. Density 0.935g / cm3, a molecular weight of 2,000,000 products, the tensile strength of 40MPa, elongation at break of 350%, flexural modulus of 600MPa, Izod notched impact punch constantly. The amount of wear (MPC method) 20mm. Application areas: ultra high molecular weight polyethylene rod can be used instead of carbon steel, stainless steel, bronze and other materials used in the textile, paper, food machinery, transportation, medical, coal, chemical and other sectors. Such as the textile industry on technical shuttle, a playing shuttle rods, gears, couplings, sweeping flower stem, buffer block, eccentric, rod bushings, swing consequences of impact-resistant wear parts. Do cover plate on the paper industry, wiper blade, compaction components, connectors, mechanical drive shaft seal, side guide wheel, scrapers, filters and the like; do powdery material transport industry hoppers, silos, chutes lining. UHMWPE Rod can do all kinds of mechanical parts, including food machinery gear, worm, worm, bearings. To do chemical pumps, valves, baffles, filter plate. Medical, but also for heart valves, short orthopedic parts, artificial joints and birth control implant. Do sports skating floor, ground balls, ski board, snowmobile parts. Applications and polyamide, polytetrafluoroethylene similar wear than steel, making gears, bearings, bearings, star wheels, valves, pumps, rails, packing, equipment lining, Slippage board, artificial joints, fiber make and ropes. Ultrahigh molecular weight polyethylene has many excellent properties, but such excellent engineering plastics, but few people know it exists, mainly due to the lack of research before the melt characteristics of ultra-high molecular weight polyethylene, the processing method is basically still stuck He pressed on behind a sintering process. In recent years, with the development of ultra-high molecular weight polyethylene processing technology, and its products have been successfully applied in many fields. Color: primary colors (white), black, other colors can be customized
