Description

Methylstyrene CAS NO 39294-88-7 is a versatile vinyl aromatic monomer, specifically a derivative of styrene, valued for its ability to enhance polymer properties such as heat resistance, chemical stability, and glass transition temperature. Its primary commercial value lies in its role as a key intermediate and co-monomer in the production of high-performance resins and specialty polymers. This product is essential for manufacturers in the polymer, coatings, and advanced materials sectors seeking to modify and improve the characteristics of their final products.

Application

• As a co-monomer in the production of heat-resistant and high-performance engineering plastics (e.g., modified polystyrene, ABS).
• In the synthesis of specialty ion-exchange resins and functional polymers for water treatment.
• For manufacturing adhesives and sealants with improved durability and chemical resistance.
• As a reactive diluent and modifier in advanced coating formulations for industrial and automotive applications.
• In the production of synthetic rubber and elastomers to enhance aging and thermal properties.
• As a chemical intermediate for pharmaceutical and agrochemical active ingredient synthesis.

Quality Control

Our Methylstyrene is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. The product undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and isomer distribution, to meet exacting industry specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent evaporation and maintain product integrity.
