Description

Tdi/ Polypropylene Glycol Glycerol Ether, Thiol Terminated CAS NO 66564-82-7 is a specialized, thiol-terminated polyether polyol derivative, a key reactive intermediate in advanced polymer synthesis. This compound matters for its unique terminal thiol (-SH) functionality, which enables efficient cross-linking and chain extension reactions, particularly in high-performance elastomers and sealants. Industries requiring durable, flexible, and chemically resistant materials, such as specialty adhesives, coatings, and polyurethane modification, are the primary users of this versatile chemical building block.

Application

• High-Performance Sealants and Adhesives: Serves as a reactive modifier to enhance flexibility, adhesion, and chemical resistance in polysulfide and polyurethane-based formulations.
• Elastomer Production: Acts as a chain extender or cross-linking agent in the synthesis of specialty rubbers and thermoplastic polyurethanes (TPU).
• Coatings and Resins: Utilized to introduce thiol functionality into coating systems, improving cure profiles, weatherability, and mechanical properties.
• Polymer Modification: Employed to tailor the properties of base polymers, such as impact modification or introducing specific reactive sites for further functionalization.
• Radical Reaction Chemistry: Functions as an efficient chain transfer agent or curing component in thiol-ene and other radical-mediated polymerization processes.

Quality Control

Our Tdi/ Polypropylene Glycol Glycerol Ether, Thiol Terminated is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, functionality, and performance. Key parameters such as thiol content, hydroxyl value, viscosity, and moisture are closely monitored. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve its thiol functionality. Keep away from strong oxidizing agents, strong acids, and bases.
