Natural Castor Oil Bio-Polyols

Overview

CanCastor proudly presents its Natural Castor Oil Bio-Polyols, a groundbreaking series of highly functional polyols engineered from sustainably sourced Ricinus communis (castor bean) oil. These innovative bio-polyols offer a compelling solution for formulators seeking to enhance the green credentials and performance of their products across diverse industrial sectors. Leveraging the inherent unique chemistry of ricinoleic acid – the predominant fatty acid in castor oil, characterized by its hydroxyl group – our bio-polyols provide a renewable, high-performance alternative to traditional petrochemical-based polyols.

Our extensive experience as industrial chemists and premium suppliers informs the meticulous development and quality control of these bio-polyols. Each batch is designed to deliver consistent reactivity, purity, and versatility, making them ideal building blocks for polyurethanes (PU), coatings, adhesives, sealants (CASE), elastomers, and specialized lubricants. CanCastor’s commitment to sustainable practices is embedded from seed to supply, ensuring our Natural Castor Oil Bio-Polyols contribute to a more circular economy without compromising on performance or economic viability. They represent a significant stride in bio-based chemistry, offering formulators the opportunity to meet stringent environmental regulations and consumer demand for eco-friendly products.

Key Physical & Chemical Properties

CanCastor's Natural Castor Oil Bio-Polyols are engineered for specific industrial requirements, presenting a range of properties crucial for high-performance applications. Our series offers various grades to meet distinct formulating needs.

• Hydroxyl Value (OHv): Typically 100 – 300 mg KOH/g (indicates the concentration of reactive hydroxyl groups, crucial for polyurethane reactions)
• Acid Value (AV): Typically < 2.0 mg KOH/g (a measure of free fatty acids, indicating purity and hydrolytic stability)
• Saponification Value (SV): Typically 175 – 190 mg KOH/g (reflects the total ester content)
• Viscosity @ 25°C: Typically 500 – 2,000 mPa·s (critical for processing, mixing, and application characteristics)
• Color (Gardner): Typically < 4 (a visual indicator of product quality and purity)
• Iodine Value (IV): Typically < 10 g I₂/100g (indicates the degree of unsaturation, influencing oxidative stability)
• Moisture Content: Typically < 0.2% (essential for preventing unwanted side reactions, particularly in polyurethane systems)
• Specific Gravity @ 25°C: Typically 0.950 – 0.970
