Endothermic CFAs
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. Find an Endothermic CFA
Exothermic CFAs
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. Find an Exothermic CFA
Endo/Exo Blend CFAs
Endothermic and Exothermic blends can have a synergistic effect that offers benefits over the use of either an endo or exo by themselves. Find an Endo/Exo Blend CFA
Custom Formulated CFAs
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. Find out more on custom CFAs
