Description

2-Methyl-m-Phenylene Diisocyanate is a specialized aromatic diisocyanate monomer, a key building block in polyurethane chemistry. Its unique methyl substitution on the aromatic ring imparts distinct reactivity and performance characteristics to the resulting polymers, offering formulators a tool to fine-tune material properties. This high-purity intermediate is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced material research and development.

Application

• Polyurethane Elastomers: Used as a core component in the synthesis of high-performance, wear-resistant elastomers for industrial parts, rollers, and wheels.
• Specialty Coatings & Paints: Serves as a cross-linking agent in high-durability, chemical-resistant coatings for automotive, industrial, and marine applications.
• Adhesives & Sealants: A critical raw material for formulating strong, flexible polyurethane adhesives and sealants with excellent bonding properties.
• Thermoplastic Polyurethanes (TPU): Employed in the production of TPUs for applications requiring a balance of flexibility, toughness, and processability.
• Polyurethane Foams: Can be used in the formulation of specialized rigid or flexible foams with tailored density and insulation properties.
• Chemical Intermediate: Acts as a precursor for other specialty chemicals, including blocking agents and other functional derivatives.
• R&D and Laboratory Use: Utilized in research settings for developing novel polymeric materials with specific performance attributes.

Quality Control

Our 2-Methyl-m-Phenylene Diisocyanate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay, isomer content, and impurity profiling, to ensure it meets precise specifications for industrial and R&D applications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment to guarantee traceability and consistency.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
