Description

Soybean Oil, Polymer With Tdi And Trimethylolpropane Soya Oil, Polymer With Trimethylol Propane And Toluene Diisocyanate CAS NO 68072-28-6 is a specialized polyurethane prepolymer derived from renewable soybean oil. This product matters as a versatile, bio-based building block that offers a sustainable alternative to conventional petrochemical polyols for formulators. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance the bio-content and performance profile of their polyurethane systems.

Application

• Bio-based Polyurethane Coatings: Used as a polyol component in formulating high-performance, sustainable coatings for industrial, automotive, and wood finishing applications.
• Adhesives and Sealants: Serves as a key raw material for producing flexible and durable polyurethane adhesives and sealants with improved environmental profiles.
• Elastomers and Castables: Employed in the manufacture of polyurethane elastomers, offering a balance of flexibility, chemical resistance, and renewable content.
• Resin Modification: Acts as a modifier for other polymer systems to introduce flexibility, adhesion, and hydrophobicity.
• Composite Materials: Used in the production of bio-composites and reinforced plastics as a resin matrix component.
• Flexible Foams: Can be utilized in the formulation of specialized, semi-flexible polyurethane foam systems.

Quality Control

Our Soybean Oil Polymer is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance as a polyol component. Key parameters such as hydroxyl value, viscosity, isocyanate content, and color are monitored. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect reactivity. Keep away from heat, sparks, and open flame.
