Description

Poly(Tolylene 2,4-Diisocyanate) is a polymeric form of toluene diisocyanate (TDI), a key aromatic isocyanate monomer. This compound is essential for producing high-performance polyurethane materials, offering enhanced handling characteristics and reactivity profiles compared to its monomeric counterparts. It is primarily required by manufacturers in the polyurethane foam, elastomer, coating, and adhesive industries seeking consistent quality and reliable supply for their formulations.

Application

• Flexible Polyurethane Foam Production: A core component in the manufacture of slabstock and molded flexible foams for furniture, bedding, and automotive seating.
• Polyurethane Elastomers: Used in the synthesis of cast, thermoplastic, and millable gum elastomers for industrial wheels, seals, gaskets, and impact-resistant parts.
• Coatings and Adhesives: Serves as a hardener in two-component polyurethane coatings, lacquers, and high-strength adhesives, providing excellent chemical resistance and durability.
• Binder Systems: Employed in the production of foundry cores and molds, as well as composite materials, where it acts as a robust polymeric binder.
• Sealants and Caulks: A critical raw material for formulating moisture-curing and two-component sealants with strong adhesion and flexibility.
• Rigid Foam Insulation: Used in appliance insulation and construction panels, contributing to superior thermal insulation properties.

Quality Control

Our Poly(Tolylene 2,4-Diisocyanate) is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a series of analytical tests including NCO content determination, viscosity measurement, and monomeric TDI content analysis. Certificates of Analysis (COA) documenting all critical parameters 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) and must be kept under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from heat, open flames, and sources of ignition.
