Blown Castor Oil

Overview

Blown Castor Oil (also known as Oxidized Castor Oil), supplied by CanCastor, represents a superior oxidized castor oil derivative engineered to elevate performance across a spectrum of industrial applications. Through a carefully controlled, proprietary oxidation process, the inherent properties of raw castor oil (CAS 8001-79-4) are significantly enhanced. This transformation yields a product with markedly increased viscosity, improved wetting characteristics, and superior film-forming capabilities, making it indispensable in demanding industrial formulations. CanCastor’s Blown Castor Oil (specific CAS for oxidized castor oil: 68187-84-8) is produced under stringent quality controls, ensuring batch-to-batch consistency and exceptional purity, critical for our global clientele in coatings, inks, lubricants, and adhesives. Our deep expertise in oleochemicals, combined with state-of-the-art processing, allows us to deliver a product that consistently meets the rigorous performance specifications of diverse industries. We ensure full transparency in our supply chain, providing clients with not just a product, but a reliable, high-performance chemical solution backed by our comprehensive technical support.

As a leading global supplier, CanCastor leverages decades of experience in the oleochemical sector. Our Blown Castor Oil is particularly valued for its unique rheological profile, which imparts excellent flow and leveling properties, as well as enhanced adhesion and flexibility to end products. This modification process involves precisely controlled air blowing at elevated temperatures, leading to the formation of new hydroxyl and carboxy groups, and increased molecular weight, fundamentally altering the oil's functionality. This makes it a preferred choice for formulators seeking to improve product stability, extend shelf-life, and optimize application performance across an expansive range of technical challenges.
