Description

Tolyene Diisocyanate, Polypropylene Glycol, Dipropylene Glycol Polymer is a specialized polyurethane prepolymer or polyol blend. This compound is engineered to serve as a key reactive intermediate, offering a balance of flexibility, adhesion, and chemical resistance in final formulations. It is primarily required by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing flexible foams and specialty polymers.

Application

• Polyurethane Coatings & Paints: As a binder component for high-performance industrial, marine, and protective coatings requiring durability and chemical resistance.
• Adhesives & Sealants: Formulating construction, automotive, and industrial adhesives that demand strong bonding and flexibility.
• Elastomers & Castable Urethanes: Production of wheels, rollers, gaskets, and other molded rubber-like parts.
• Flexible Foam Systems: Used in the manufacture of customized foam products for cushioning and insulation applications.
• Waterproofing Membranes & Sealants: A critical raw material in construction chemicals for creating durable, waterproof barriers.
• Composite Materials: As a matrix resin or modifier in fiber-reinforced plastics and other composite systems.
• Industrial Binders & Encapsulants: For potting, encapsulation, and binding applications in electronics and construction.

Quality Control

Our Tolyene Diisocyanate, Polypropylene Glycol, Dipropylene Glycol Polymer is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of NCO content, viscosity, and moisture levels. A Certificate of Analysis (COA) is provided with every shipment to guarantee compliance with agreed specifications.

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 / 59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
