Calcium Stearate

Calcium Stearate is a high-purity, white, finely powdered metallic stearate widely recognized for its exceptional lubricating and stabilizing properties in the plastics, rubber, and pharmaceutical industries. As the calcium salt of stearic acid, this versatile additive serves as an efficient acid scavenger, release agent, and waterproofing agent across a broad spectrum of manufacturing processes. Our Calcium Stearate is manufactured under stringent quality controls to ensure consistent particle size distribution, low moisture content, and a purity exceeding 99%, making it the preferred choice for PVC heat stabilization, polyolefin processing, and food-contact applications. With its excellent compatibility with various polymers and its non-toxic nature, Calcium Stearate continues to be an indispensable component for formulators seeking reliability, performance, and regulatory compliance in their end products.
