Urethane Grade Castor Oil

CanCastor's Urethane Grade Castor Oil stands as a highly refined, premium natural polyol specifically engineered to meet the rigorous demands of advanced polyurethane (PU) and prepolymer manufacturing. This exceptional bio-based polyol is meticulously processed from select Ricinus communis seeds, preserving its unique ricinoleic acid structure while enhancing purity for sensitive chemical reactions. It is the material of choice for formulators seeking unparalleled consistency, predictable reactivity, and superior performance in their end products, offering a sustainable alternative without compromising mechanical properties.

Optimized for Polyurethane Systems

Unlike standard industrial grades, CanCastor's Urethane Grade Castor Oil undergoes a specialized refining process to minimize impurities that can disrupt polymerization, lead to inconsistent curing, or introduce unwanted side reactions such as gassing and foaming. We ensure tightly controlled hydroxyl functionality, exceptionally low moisture content, and precise acidity levels – critical parameters for stable and reproducible results in isocyanate-terminated prepolymers and other high-performance PU systems. This rigorous control guarantees reliable performance, making it indispensable for applications where hydrolytic stability and consistent processing are paramount.

Key Advantages for Formulators

• Predictable Reactivity: Tightly controlled specifications ensure consistent reaction kinetics with isocyanates, leading to reliable pot life and cure profiles.
• Enhanced Stability: Exceptionally low moisture content prevents premature reaction with isocyanates, extending shelf life and improving system stability.
• Superior Hydrolysis Resistance: The natural structure of castor oil contributes to excellent hydrolytic stability in the final PU product, crucial for demanding environments.
• Increased Bio-Content: Integrates a renewable, bio-based polyol into formulations, supporting sustainability goals without sacrificing performance.
• Versatile Performance: Imparts a desirable balance of hardness, flexibility, and impact resistance, along with excellent adhesion and chemical resistance in various applications.

Typical Applications & Benefits

• Polyurethane Elastomers & Prepolymers: As a primary natural polyol, it is vital for manufacturing high-performance cast elastomers, industrial rollers, mining screens, and various molded parts. It forms the stable backbone for isocyanate prepolymers, offering superior flexibility, abrasion resistance, and long-term durability.
• PU Coatings, Adhesives & Sealants (CAS): Widely incorporated into moisture-cure and two-component coatings for metal, concrete, and wood, providing excellent adhesion, weatherability, and chemical resistance. In sealants and joint fillers, it significantly enhances tack, elasticity, and overall long-term durability.
• Specialty Polymers & Resins: Ideal for formulating impact-resistant linings, resilient flooring systems, and potting compounds where a delicate balance of hardness and flexibility is required. It enables formulators to increase the renewable content of their products without compromising critical mechanical performance attributes.
