MDSÂ® is an extruded â€œmolyâ€ filled nylon 6/6, which is gray in color. The addition of particles of molybdenum di-sulfide enhances the surface lubricity and wear resistance over unfilled nylon. In applications requiring high lubricity, this material may be a good candidate. In addition to the greater lubricity there are many additional property enhancements that occur. MDSÂ® has enhanced properties which make it an ideal material to replace metals in machinery. It can increase the life of many moving parts as well as provide a noise reduction benefit and requires less lubrication. A very stable compound with many industrial applications.
