Chemical Foaming Agent Product Selection Quick Guide

Bergen International has focused exclusively on providing plastic processors with the best performing chemical foaming agents for low-density foaming processes since 1998. Below are some of the typical chemical foaming agents that have been used very successfully in various applications, base resins, and processes for a variety of purposes.

This information is provided as a quick guide only. We have a large range of products for a wide range of polymers and applications, but we offer this information as a helpful starting point for chemical foaming agent specifying. Please call us to discuss your application so we can offer additional assistance.

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
