Nylon MD

Nylon MD [Nyla­tron®, Sus­tamid®, Tecamid® 6/6 MDS, Unipa® Ld]


  • Nylon MD is nylon 6/6 with molyb­de­num disul­fide added to improve the mechan­i­cal and ther­mal properties.
  • Espe­cially suited to appli­ca­tions in which lubri­ca­tion is imprac­ti­cal or undesirable
  • Wear resis­tant
  • Strong and rigid
  • Dimen­sional stability
  • Low sur­face friction
  • Heat resis­tant

Com­mon uses

  • Bear­ings and bushings
  • Valve seats
  • Thrust wash­ers
  • Wear sur­faces
  • Rollers
  • Gears
  • Sleeves
  • Form­ing dies
  • Tool­ing fixtures
