Description

1,3-Divinylbenzene is a high-purity, reactive aromatic monomer essential for advanced polymer synthesis. Its bifunctional vinyl groups make it a critical cross-linking agent, significantly enhancing the thermal stability, chemical resistance, and mechanical strength of final polymer networks. This compound is vital for manufacturers in the specialty plastics, advanced resin, and high-performance elastomer industries seeking to develop superior materials.

Application

• Cross-linking Agent for Polymers: Used to create three-dimensional networks in polystyrene, polyesters, and other resins, improving their heat distortion temperature and solvent resistance.
• Production of Ion-Exchange Resins: Serves as a key monomer in the synthesis of styrene-divinylbenzene copolymers, which form the matrix for strong acid cation and strong base anion exchange resins used in water purification and chemical processing.
• Synthesis of Specialty Elastomers: Incorporated into the production of synthetic rubbers to enhance cross-link density, resulting in improved tensile strength and durability.
• Manufacture of Gel Permeation Chromatography (GPC) Media: Used to produce controlled-porosity beads for the separation and analysis of macromolecules.
• Intermediate for Fine Chemicals: Acts as a building block in organic synthesis for pharmaceuticals, agrochemicals, and other specialty compounds.
• Composite Materials: Enhances the properties of fiber-reinforced plastics and other composite materials by forming a robust polymeric matrix.

Quality Control

Our 1,3-Divinylbenzene is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications for reactive monomer applications. Certificates of Analysis (COA) documenting purity, isomer content, and inhibitor levels are provided with every shipment to guarantee supply consistency and reliability for your polymerization processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at temperatures between 2°C and 8°C (refrigerated) under an inert atmosphere (e.g., nitrogen) to minimize oxidation and polymerization. Due to its highly volatile nature, keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to prevent evaporation and moisture ingress.
