Stearates

About Product

Stearates are metallic salts of stearic acid, widely used in the plastic and rubber industry as lubricants, stabilizers, mold-release agents, and anti-caking agents. Common types include calcium, zinc, magnesium, and aluminum stearates. They improve processing efficiency, enhance flow, and prevent sticking during molding and extrusion. Stearates also contribute to thermal stability, clarity, and surface finish in various plastic and rubber compounds.

Chemical Formula: Varies by type (e.g., Zinc Stearate – C36H70O4Zn)

Chemical Code: Varies (e.g., Zinc Stearate – CAS 557-05-1)
