Description

Blown Castor Oil is a chemically modified vegetable oil produced by blowing air through heated castor oil, resulting in a product with increased viscosity, hydroxyl value, and excellent oxidative stability. This specialized process creates a versatile, non-drying oil that is crucial for formulating high-performance industrial products requiring superior lubricity, flexibility, and water resistance. It is an essential raw material for manufacturers in the coatings, lubricants, plastics, and textile chemical industries seeking to enhance product durability and performance.

Application

• Coatings & Inks: Acts as a plasticizer and viscosity modifier in alkyd resins, polyurethane coatings, and printing inks, improving film flexibility, gloss, and adhesion.
• Lubricants & Greases: Serves as a high-performance base oil or additive in specialty lubricants, metalworking fluids, and biodegradable greases, offering excellent lubricity and load-bearing capacity.
• Polymer & Plastic Industry: Used as a plasticizer and processing aid for PVC, nitrocellulose, and synthetic rubbers, enhancing flexibility and reducing brittleness.
• Textile Chemicals: Employed in the formulation of textile lubricants, softeners, and finishing agents to improve fiber handling and fabric quality.
• Leather Processing: Functions as a fatliquoring agent to soften and waterproof leather, improving its tensile strength and durability.
• Adhesives & Sealants: Imparts flexibility and improves the bonding characteristics of various adhesive and sealant formulations.
