Description

Divinylbenzene is a crucial bifunctional monomer containing two vinyl groups, making it a highly reactive cross-linking agent in polymer chemistry. Its primary value lies in its ability to form three-dimensional polymer networks, imparting enhanced thermal stability, mechanical strength, and chemical resistance to the final materials. This product is essential for manufacturers in the polymer, ion exchange resin, and specialty plastics industries seeking to produce high-performance, durable materials.

Application

• Cross-linking Agent for Polymers: Used in the production of styrene-based copolymers to enhance structural integrity and heat resistance.
• Ion Exchange Resin Synthesis: A key raw material for manufacturing strong cation and anion exchange resins used in water purification, chemical processing, and hydrometallurgy.
• Production of Specialty Plastics & Elastomers: Imparts improved durability and solvent resistance to advanced plastic and rubber compounds.
• Gel Permeation Chromatography (GPC) Media: Serves as a base material for porous polymer beads used in analytical column packing.
• Unsaturated Polyester Resins (UPR): Acts as a reactive diluent and cross-linker to modify the cure profile and final properties of resins for composites.
• Adhesive & Coating Formulations: Enhances the cross-link density and performance of high-strength industrial adhesives and protective coatings.

Quality Control

Our Divinylbenzene is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and isomer distribution, to ensure it meets precise customer and industry specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert gas (e.g., nitrogen) and keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C to minimize polymerization and maintain stability.
