Dry #1 Refined Castor Oil
Dry #1 Refined Castor Oil is a premium grade of castor oil developed for a variety of uses including urethanes, packaging adhesives, & reactive hot melts.
- Extremely low moisture content
- Clear, viscous, light color
- Non-drying and stable
- Lubricity and plasticization
- Penetration and surface wetting
- Pigment/dye dispersion
- Base compound for reactions
Dry #1 Refined Castor Oil is used in food packaging, where freshness is critical, creating a superior moisture vapor barrier.
Dry #1 Refined Castor Oil a key natural polyol for a multitude of urethane reactions, where low moisture is critical during the reaction phase.
Dry #1 Refined Castor Oil is used in polyurethane (PUR) hot melts in industries from high volume manufacturing to DIY and home repair. Polyurethane hot melts are non-toxic, quick setting, & offer temperature and weather resistance.
Vertellus supplies a variety of castor oil grades the uses of which are dictated by acid value, moisture level, color, and purity. Castor oil is a triglyceride of fatty acids, with the fatty acid content being approximately 90% ricinoleic acid. Ricinoleic acid is an 18-carbon acid having a double bond in the 9-10 position and a hydroxyl group on the 12th carbon. Its remarkably constant composition, hydroxyl functionality and unsaturation, make it uniquely versatile as a naturally occurring compound.
While castor oil is available from several sources, regardless of origin, the chemical nature and composition are remarkably uniform. Typical values in the table below hold true for the Dry #1 Refined Castor Oil.
