Chinese, said monomer cast nylon PA nylon. "Plastic steel, high performance," extremely versatile. It is light weight, high strength, a variety of unique performance-lubricating, wear, corrosion, insulation and other self. Is widely used plastic, almost all industrial fields. Currently on the market commonly cast nylon moderators have the following: 1: MC Nylon (Ivory): unmodified cast nylon 6, nylon 66 features and extremely close to its good overall performance, high strength, stiffness and hardness, resistance creep, wear resistance, heat aging, good machining properties. 2: MC901 (blue): This modification has striking blue nylon 6, higher than normal cast nylon toughness, flexibility and good resistance to fatigue, proved to be an ideal material for gears, rack and transmission gear. 3: PA6 + oil (green): This cast nylon 6 is a veritable self-lubricating nylon, is designed for the manufacture not lubricated, high load and low speed parts developed, which greatly broadens the scope of application of nylon, it than nylon low friction coefficient (which can be reduced by 50%) and improved wear resistance (can be increased 10-fold). 4: PA6 + molybdenum disulfide (gray and black): molybdenum disulfide-containing powder, can not affect the unmodified cast nylon in high impact and fatigue resistance while increasing its carrying capacity and wear resistance, it is very widely used to make gears, bearings, star wheels and sets.
