Features & Benefits

Labeling Claims
Benefits
  • This compound has high temperature stability and high pressure resistance
  • It has reduced cold flow
  • The MoS₂ content reduces friction and abrasion
  • Product Highlights
    • Bronze filler offers better dimensional stability, higher thermal conductivity, lower creep and cold flow. It also provides improved hardness, lower wear, and a higher comprehensive strength.
    • Molybdenum Disulfide filler is used frequently in combination with others to increase surface hardness, stiffness, and to reduce the starting coefficient of friction and steady-state wear. Its effect on electrical and chemical properties is negligible.
