3. Product Overview

Blown Castor Oil is a chemically modified castor oil produced by passing controlled air or oxygen through refined castor oil at elevated temperatures. This oxidation process increases molecular weight and polarity, resulting in higher viscosity, enhanced tackiness, and improved film-forming properties compared to untreated castor oil.

At Nova Industries, Blown Castor Oil is manufactured under precisely monitored blowing conditions, allowing tight control over viscosity build-up and oxidation level. This ensures consistent performance from batch to batch—an essential requirement for industrial buyers who rely on predictable rheology and adhesion characteristics.

Blown Castor Oil is widely used where thickening, binding, and film strength are required. Compared to raw or refined castor oil, it offers superior body, better surface adhesion, and improved resistance to flow under load. Buyers select this product for applications where functional performance matters more than simple lubrication.
