About Lesson

Simple Soaps

Tend to break down at higher temperatures and not shear as well as complex soaps

  • Lithium Stearate
  • Lithium 12-hydroxystearate
  • Calcium anhydrous
  • Calcium hydrated (cup grease)
  • Aluminum
  • Barium
  • Sodium

 

 

 

Non-Soap Thickeners

  • Calcium Sulfonate
  • Calcium Sulfonate Complex
  • Polyurea (Good oxidative stability, sealed-for-life applications)
  • Clay (Good for very high temp applications w/ no dropping point)

 

 

 

 

 

Complex Thickeners

Tend to be more shear stable and resist high temperature breakdown better than simple soaps

  • Lithium Complex
  • Aluminum Complex
  • Calcium Complex
    • Shorter chain organic acid used to add stability
    • Cross-linking of long chains
    • High temperature stability
    • Allows use of resulting greases at higher temperatures
