Product Data Sheet Divinylbenzene The Versatile Divinylbenzene (DVB) is an extremely versatile cross-linking agent that also improves Cross-Linking Agent polymer properties. As a result, it has been used to manufacture adhesives, plastics, for Improving elastomers, ceramics, biological materials, coatings, catalysts, membranes, Material Properties pharmaceuticals, specialty polymers, and ion exchange resins. It is also important that just a small amount of DVB is needed to improve both chemical and physical properties. This efficiency in use allows you to gain selected property improvements without hindering others. In short, DVB allows you to create materials not otherwise possible and enhance the properties of existing materials in many ways. For example, when used to cross-link polystyrene, DVB increases solvent resistance, heat distortion, impact strength, tensile strength, and hardness. And as little as 0.5% divinylbenzene in a styrene polymerization makes the polymer insoluble. DuPont Offers DuPont recognizes that your requirements for DVB may not always be the same in every Three Grades of application. That’s why we offer three levels of DVB concentration, allowing you to DVB to Best Match balance economy with functionality. For the greatest economy on an active ingredient Your Needs basis, DVB-55 is your best choice. DVB-63 and DVB-HP (80% DVB) work best when you need high levels of dual double bond functionality to cross-link vinyl polymeric systems with the least amount of material. DVB-HP should also be considered when higher concentrations of ethylvinylbenzene (the major complementary component in these DVB products) do not provide any additional benefits—even though the ethylvinylbenzene will react with most unsaturated systems.
