Calcium Stearate

Overview

Calcium Stearate is a high-performance, white, waxy, free-flowing powder widely used across multiple industries for its excellent Anti-Caking (E470a), Lubrication, Thermal Stability, and Moisture-Repellent properties. It is insoluble in water and soluble in organic solvents, making it ideal for applications requiring chemical inertness and consistent performance. At CORE METCHEM, our Calcium Stearate is manufactured using ethically and responsibly sourced vegetable-based raw materials, ensuring superior quality, sustainability, and compliance with industry standards. At CORE METCHEM, Calcium Stearate is processed using controlled reaction techniques to achieve superior purity, uniform particle size and excellent free-flowing properties. It gives the best Anti-caking properties (Categorised as E470a), while used in powdered dehydrated food products. It delivers strong lubricity and enhanced process ability, making it ideal for polymer compounding, PVC formulations, rubber processing, coatings, cosmetics and several technical applications. With its Hydrophobic nature it gives an excellent waterproofing property to construction chemicals dealing in waterproofing solutions. Our material conforms to strict industrial standards and is suitable for both domestic and export markets.
