Description

p-Divinylbenzene 85 is a high-purity grade of the organic compound para-divinylbenzene, a key monomer and crosslinking agent. Its value lies in its ability to introduce reactive vinyl groups into polymer chains, enabling the creation of robust, three-dimensional network structures. This product is essential for manufacturers in the polymer, specialty resin, and advanced materials industries seeking to enhance the thermal stability, mechanical strength, and chemical resistance of their products.

Application

• Crosslinking Agent for Polymers: Primary use in the production of ion-exchange resins, styrenic polymers, and high-performance plastics to improve durability and heat resistance.
• Synthesis of Specialty Resins: Key monomer for manufacturing macroporous adsorbent resins, gel permeation chromatography (GPC) media, and polymeric supports for catalysts.
• Production of Composite Materials: Used in fiber-reinforced plastics (FRP) and coatings to create dense, cross-linked matrices with enhanced properties.
• Chemical Intermediate: Serves as a building block in organic synthesis for pharmaceuticals, agrochemicals, and fine chemicals.
• Adhesive & Sealant Formulations: Imparts improved cohesive strength and environmental resistance in advanced adhesive systems.
