Description

Castor Oil, Ester With Pentaerythritol is a high-performance, bio-based polyol ester derived from the reaction of castor oil with pentaerythritol. This chemical modification significantly enhances its oxidative stability and thermal properties, making it a superior, sustainable alternative to conventional petrochemical-based intermediates. It is a critical raw material for industries requiring high-performance, environmentally friendly polymers and lubricants, particularly in the manufacturing of alkyd resins, polyurethane elastomers, and specialty lubricating greases.

Application

• Alkyd Resins: A key monomer for producing high-quality, fast-drying, and durable alkyd resins used in industrial coatings, marine paints, and automotive finishes.
• Polyurethane Systems: Functions as a bio-based polyol for manufacturing flexible and rigid polyurethane foams, elastomers, adhesives, and sealants with enhanced hydrolytic stability.
• Lubricants & Greases: Used as a base stock or additive in formulating high-temperature, biodegradable lubricating greases and synthetic esters for demanding applications.
• Plasticizers: Acts as a secondary plasticizer and stabilizer in PVC and other polymer systems, improving flexibility and low-temperature performance.
• Surface Coatings: Employed in the synthesis of corrosion-resistant primers, varnishes, and linseed oil replacements for protective coatings.
• Adhesives & Inks: Serves as a reactive diluent and modifier in adhesive formulations and specialty printing inks to adjust viscosity and film properties.

Quality Control

Our Castor Oil, Ester With Pentaerythritol is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, hydroxyl value, acid value, viscosity, and color. Certificates of Analysis (COA) documenting full specification compliance are provided with every shipment. We support compliance with relevant global standards, including REACH, and can tailor specifications to meet specific customer requirements for industrial or specialty grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). As the product is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term storage of bulk quantities. Keep away from strong oxidizing agents, heat, and ignition sources.
