Calcium Stearate is a widely used metallic soap that functions as both an internal/external lubricant and a mild heat stabilizer, commonly used alongside PVC stabilizer packages to neutralize trace hydrochloric acid released during processing.

It is non-toxic and food-contact friendly, which has made it a standard choice across a broad range of general-purpose polymer compounds.

Key Benefits

  • Dual-action lubrication (internal and external)
  • Acts as an acid scavenger / co-stabilizer in PVC
  • Non-toxic, suitable for food-contact formulations
  • Improves melt flow and mould release
  • Cost-effective, broadly compatible additive
