Barium Stearate is the barium soap derived from stearic acid, a fatty acid found in animal fats and vegetable oils and supplied as a fine, hydrophobic powder, barium stearate acts as a heat/light stabilizer and lubricant in PVC and other polymers, improving melt flow, reducing sticking, and aiding mold release. In rubber compounding, coatings, inks, waxes, and greases, barium Stearate increases water repellency and surface slip while maintaining process stability. Also known as Barium distearate; Octadecanoic acid, barium salt (2:1) by Barium Stearate supplier and manufacturer. We are the leading, trusted barium stearate supplier worldwide and in the United States, with reliable lead times and global supply capability.

Barium Stearate is a highly effective heat stabilizer for polyvinyl chloride (PVC) and other polymers due to its ability to neutralize hydrochloric acid (HCl).
Barium Stearate's function as a lubricant is attributed to its "soap" structure, which allows it to form a lubricating film on the surface of material and processing equipment.
Provides heat/light stabilization and lubrication to reduce sticking and improve melt flow.
Commonly 0.2–2% w/w, depending on formulation and co-stabilizers.
Standard and micronized grades available.
Yes, export ready with COA, TDS, SDS, and compliance certificates.
