In plastics, metallic stearates are used as lubrication aids, mold release agents, or acid scavengers due to their high thermal stability properties. Lastly, these polymer stabilizers are used in plastics melt processing to optimize overall production output and produce finished articles with smoother surfaces.

The most common metallic stearates which are used in polymer industries:

• Calcium Stearate
• Zinc Stearate
• Magnesium Stearate
• Sodium Stearate
• Aluminum Stearate
