Description

Ethylstyrene CAS NO 28106-30-1 is a versatile aromatic monomer belonging to the vinyltoluene family, characterized by an ethyl group substituted on the styrene ring. This structural modification imparts distinct reactivity and physical properties, making it a valuable intermediate for polymerization and specialty synthesis. It is essential for manufacturers in the polymer, resin, and fine chemical industries seeking to modify material characteristics such as glass transition temperature, solubility, and cross-linking density.

Application

• Polymer Modification: Serves as a co-monomer in the production of specialty styrenic copolymers and terpolymers to tailor flexibility, thermal stability, and chemical resistance.
• Synthetic Resins: A key raw material in the formulation of unsaturated polyester resins (UPR) and alkyd resins for coatings, composites, and laminates.
• Adhesive & Sealant Formulations: Used to enhance the performance and adhesion properties of pressure-sensitive and structural adhesives.
• Oilfield Chemicals: Employed in the synthesis of polymers for use as viscosity modifiers, fluid loss additives, and other downhole chemical applications.
• Fine Chemical Synthesis: Acts as a building block for pharmaceuticals, agrochemicals, and other complex organic molecules.
• Specialty Elastomers: Incorporated into synthetic rubber formulations to improve processing and end-product performance.

Quality Control

Our Ethylstyrene is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer and industry specifications. 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, well-ventilated area away from heat sources, strong acids, and organic solvents. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent evaporation and potential contamination.
