Products by Bergen International

Endothermic chemical foaming agents are chemicals that take heat away from the chemical reaction. This produces foams with a much smaller cell structure, resulting in improved appearance and better physical properties.

Exothermic chemical foaming agents generate heat during the decomposition process. They liberate more gas per gram of foaming agent than endothermic agents and higher gas pressure.

Endothermic and Exothermic blends can have a synergistic effect that offers benefits over the use of either an endo or exo by themselves.

Bergen International prides itself on our ability to work with you to develop the exact blend that offers the best set of performance/cost benefits for your specific process and polymer.

Bergen International offers XO-230 and XO-331 Chemical Foaming Agents specifically formulated for Polycarbonate and other high temperature polymers. Our XO-230 Chemical Foaming Agent is intended for weight reduction. It provides maximum density reduction, sink mark removal, and warp reduction in...
