Description

Tdi/Polypropylene Glycol Glyceryl Triether/Butylene Glycol CAS NO 67723-14-2 is a specialized polyether polyol derivative, synthesized from toluene diisocyanate (TDI), polypropylene glycol, and butylene glycol. This compound serves as a crucial reactive intermediate and building block in the formulation of high-performance polyurethane systems. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product flexibility, durability, and chemical resistance.

Application

• As a key polyol component in the production of flexible and semi-flexible polyurethane foams.
• Formulation of high-performance polyurethane coatings and paints with enhanced weatherability and adhesion.
• Manufacture of specialty polyurethane adhesives and sealants for automotive and construction applications.
• Production of elastomers for industrial parts requiring a balance of toughness and flexibility.
• Used in the synthesis of prepolymers for castable and thermoplastic polyurethane (TPU) products.
• As a reactive modifier to adjust the hardness and crosslink density in various polymer systems.

Quality Control

Our Tdi/Polypropylene Glycol Glyceryl Triether/Butylene Glycol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. Certificates of Analysis (COA) documenting key parameters such as hydroxyl value, viscosity, and water content are available upon request to support your quality assurance protocols.

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 material is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use to prevent absorption of atmospheric moisture which may affect product performance.
