Description

1,2-Divinylbenzene is a high-purity, reactive aromatic monomer containing two vinyl groups on a benzene ring. This compound matters as a critical cross-linking agent and building block in advanced polymer synthesis, enabling the creation of materials with enhanced thermal stability and mechanical properties. Industries requiring specialty resins, ion-exchange polymers, and high-performance coatings rely on its unique bifunctional reactivity. Our global supply of 1,2-Divinylbenzene CAS NO 91-14-5 ensures consistent quality and reliable availability for demanding industrial applications.

Application

• Cross-linking Agent for Polymers: Essential for producing rigid, three-dimensional network structures in styrenic resins, enhancing heat resistance and dimensional stability.
• Ion-Exchange Resin Synthesis: Serves as a key monomer in the manufacture of strong acid cation exchange resins and other functional polymeric adsorbents.
• Specialty Coatings and Adhesives: Used to formulate high-performance coatings, sealants, and adhesives with superior chemical and environmental resistance.
• Composite Materials: Incorporated as a reactive diluent and co-monomer in fiber-reinforced plastics (FRP) and other composite systems.
• Chemical Intermediate: Utilized in organic synthesis for creating more complex molecules in pharmaceutical and agrochemical research.
• Modifier for Elastomers: Improves the properties of synthetic rubbers and other elastomeric materials.

Quality Control

Our 1,2-Divinylbenzene is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and isomer content, to ensure compliance with agreed specifications and industry standards. Certificates of Analysis (COA) documenting identity, purity, and relevant physical properties are provided with every shipment. We adhere to global regulatory frameworks including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Recommended storage temperature is 2-8°C (36-46°F) to minimize polymerization and oxidation. This product is easily oxidized and should be handled under an inert atmosphere such as nitrogen for long-term storage or when dispensing. Keep away from strong oxidizing agents and initiators.
