Tungsten Disulfide

Tungsten Disulfide (WS2) is a solid lubricant that does not depend on absorption for its lubricating qualities. Offering exceptional advantages to the plastics industry, WS2 is used to solve problems concerning mold release and flow.

Mold Performance

  • Lowers temperature and pressure requirements
  • Improves flow
  • Lowers residual stress
  • Reduces scrap
  • Higher quality parts
  • Shorter cycle times


  • Reduces wear
  • Reduces lubrication requirements of plastics
  • Eliminates scoring, galling and seizing
  • Facilitates motion
  • Permits tighter clearances

Mold Release

  • Decreases / eliminates use of mold release products
  • Semi-permanent
  • Does not transfer to molded part
  • Increases tool life
  • Maintains sharp edges
