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

Chemical Foaming Agents for the Plastics Processing Industry

Bergen International focuses exclusively on providing plastic processors with the best performing chemical foaming agents (CFAs) for low-density foaming processes.

Foamazol™ chemical foaming agents yield many benefits to plastics processors such as: finer cells for better physical properties including smoother surfaces, increased strength and sink mark elimination…reduction of polymer usage, saving you money…quicker cycle times and increased throughput speed…elimination of outgassing so parts can be finished immediately…and, most Foamazol™ chemical foaming agents are environmentally friendly so handling and processing are safe and many grades are available for applications involving food contact.

Foamazol™ chemical foaming agents are available for many processes such as, injection molding, co-injection injection molding, gas counter-pressure molding, rotational molding, structural foam molding, co-extrusion, chemical foam extrusion, direct gas extrusion, wood-plastic composites extrusion, and wire & cable extrusion processes.

Bergen manufactures various types of Foamazol™ chemical foaming agents including endothermic, exothermic and endo/exo blends….in a variety of forms such as pelletized masterbatches, powders and liquids…for a range of polymers including polyolefins, styrenics, engineering resins or PVC…at a variety of decomposition temperatures.

Our Foamazol™ chemical foaming agents come in many forms and varieties to meet virtually any processing requirement, and we have a great depth of experience in custom formulating chemical foaming agents. We are so committed to our customers that we've recently added a new processing laboratory, allowing you the opportunity to fine tune your process at our facility, saving you R&D costs, equipment and time.
