1: Oil Nylon (Oil casting Nylon) Oil Nylon, is the new engineering plastics that developed by Guangzhou Engineering Plastics Industries Company. was the first authentic lubricating nylon that builds the liquid lubricant system during the processing stage,which makes its coefficient of friction is 50% lower than the general Nylon, the wear-resistance is 10 times than the generalones. 2: MC901 (Blue) This improved MC Nylon, has striking blue color, which is better than general PA6/PA66 in the performance of toughness, flexibility, fatigue-resistance and so on. It is the perfect material of gear, gear bar, transmission gear and so on. 3: MC Nylon + Oil (Green) Oil MC Nylon is specially developed for the parts of non-self-lubrication, heavy-loading and low-speed-running, which obviously resulted in a substantial increase in bearing life -- 5 times that of general plastics and 25 times that of phosphor bronze! 4 : MC Nylon + MSO2 (Light black) MC Nylon added MSO2 can remain the impact-resistance and fatigue-resistance of casting nylon, as well as it can improve the loading capacity and wear-resistance. It has a wide application in making gear, bearing, planet gear, seal circle and so on. 5 : Oil Nylon + Carbon (Black) Oil Nylon added carbon, has the very compact and crystal structure, which is better than the general casting nylon in the performance of high mechanical strength,wear-resistance, anti-aging, UV resistance and so on. It is suitable for making the bearing and other wear mechanical parts.
