Tecamid MDS - Molybdenum Disulfide Filled (MDS)

Nylon is one of the most widely used and versatile thermoplastic resins. Its combination of physical properties versus its price makes it a favorite choice for numerous applications. Nylon has a consistent history of replacing other materials including: metal, brass, bronze, aluminum, and rubber. In replacing metal gears in machinery, nylon can be advantageous because of its ability to reduce noise, use less lubrication and increase gear life. TECAMID™MDS is an extruded "moly" filled nylon 6/6, which is gray in color. The addition of particles of molybdenum disulfide 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 enhancementsthat occur.

Tecamid ST
  • Low surface friction
  • Increased surface hardness
  • Increased heat resistance
  • Higher tensile properties
  • Improved dimensional stability

TECAMID™MDS 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.
