Linseed Oil is a natural oil derived from flax seeds (Linum usitatissimum) , widely used in industrial applications for its drying and film-forming properties. It serves as a key ingredient in paints, varnishes, inks, and wood treatments. In its epoxidized form, linseed oil acts as a bio-based plasticizer and stabilizer in polymers like PVC, offering a sustainable alternative to petrochemical additives. Its versatility also extends to sealants, resins, and cosmetic formulations, making it a valuable component in both traditional and eco-friendly manufacturing.
