Description

Castor Oil, Polymer With Polyethylene Glycol And Tdi is a polyurethane prepolymer derived from the reaction of castor oil, polyethylene glycol (PEG), and toluene diisocyanate (TDI). This specialized polymer is valued for its unique combination of flexibility, hydrolytic stability, and biodegradability imparted by the renewable castor oil component. It is primarily sought by manufacturers in the polyurethane, adhesive, and coatings industries for formulating high-performance, environmentally-conscious products.

Application

• Flexible Polyurethane Foams: Used as a key prepolymer component to produce soft, resilient foams with enhanced hydrolytic stability.
• Bio-based Polyurethane Coatings: Serves as a renewable raw material for formulating durable, flexible, and water-resistant surface coatings.
• Adhesives and Sealants: Imparts excellent adhesion and flexibility in formulations for construction, automotive, and packaging applications.
• Elastomers: A building block for casting or molding flexible, tough polyurethane elastomers used in industrial parts.
• Controlled-Release Matrices: Utilized in agricultural or pharmaceutical applications for creating biodegradable carrier systems.
• Textile and Leather Finishing: Acts as a soft, durable finishing agent to improve the handle and performance of fabrics and leather.

Quality Control

Our Castor Oil, Polymer With Polyethylene Glycol And Tdi is produced under a strict quality management system. Each batch undergoes comprehensive analysis to ensure consistency in key parameters such as NCO content, viscosity, and hydroxyl value. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction. Recommended storage temperature is 15-25°C. Keep away from heat and open flame.
