Description

Castor Oil, Polymer With Adipic Acid, Diethylene Glycol, And Glycerol is a specialized polyol ester polymer derived from renewable castor oil. This engineered polymer offers a unique combination of flexibility, hydrolytic stability, and adhesion promotion, making it a valuable intermediate for high-performance formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in polyurethane systems, where its properties enhance product durability and performance.

Application

• Polyurethane Systems: Used as a reactive polyol component in the production of flexible foams, coatings, adhesives, and elastomers, imparting flexibility and improved hydrolytic stability.
• Industrial Coatings & Inks: Serves as a resin modifier or building block in alkyds and polyurethane coatings, enhancing adhesion to difficult substrates, flexibility, and chemical resistance.
• Adhesives & Sealants: Acts as a tackifier and flexibility enhancer in both solvent-based and reactive adhesive formulations, improving bond strength and longevity.
• Plasticizers & Polymer Modification: Functions as a secondary plasticizer or compatibilizer in PVC and other polymer blends to improve low-temperature performance and reduce migration.
• Lubricants & Functional Fluids: Employed as a base stock or additive in biodegradable lubricants and greases, offering excellent lubricity and high viscosity index.

Quality Control

Our Castor Oil, Polymer With Adipic Acid, Diethylene Glycol, And Glycerol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as hydroxyl value, acid value, viscosity, and color. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your specifications and industry standards.

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). This product is easily oxidized; for long-term storage, consider blanketing with an inert gas (e.g., nitrogen) to maintain product integrity. Keep away from strong oxidizing agents, acids, and bases.
