Product Application

Ion Exchange Resins (Primary Application):

DVB is a key crosslinking agent for producing strongly acidic cation exchange resins​ and macroporous adsorbent resins. In resin synthesis, DVB copolymerizes with styrene to form spherical beads; its content (usually 4% – 12%) determines the resin’s crosslinking density, mechanical strength, swelling degree, and selectivity. Higher DVB content means higher crosslinking density and greater mechanical properties, but lower swelling.

Polymer Modification:

Reinforced Plastics:​ Used to manufacture high-strength, high-modulus fiberglass-reinforced plastics (FRP) and artificial stone.

Rubber Vulcanization Agent / Comonomer:​ As a comonomer in synthetic rubbers such as styrene-butadiene rubber (SBR) to improve properties.

Ion Exchange Membranes:​ Used to produce ion exchange membranes with specific properties.

Coatings & Adhesives:

High-Solids Coatings:​ As a reactive diluent, it participates in curing reactions, reducing VOC emissions.

Pressure-Sensitive Adhesives (PSAs):​ Improves cohesion strength and heat resistance of PSAs.

Specialty Polymers:

Expandable Polystyrene (EPS):​ Small amounts of DVB can be used as a crosslinking agent to improve heat resistance.

Conductive Polymers:​ Copolymerized with pyrrole, thiophene, etc., to prepare conductive composites.

Analytical Chemistry:

Solid-Phase Microextraction (SPME):​ As a coating material for sample pretreatment to enrich volatile organic compounds.

Other Uses:

Photoresists:​ Used as a component of photoresists in the microelectronics industry.

Organic Synthesis Intermediate:​ For synthesizing other functional compounds.

Storage

Usually stored with a polymerization inhibitor (e.g., TBC). Store in a cool, ventilated warehouse. Keep away from fire and heat. Storage temperature should not exceed 35°C. Packaging must be sealed and protected from air. Store separately from oxidizers, acids, and bases; do not mix. Use explosion-proof lighting and ventilation. Prohibit spark-generating machinery and tools. The storage area should be equipped with spill response equipment and suitable containment materials.
