Endo/Exo Chemical Foaming Agent Blends

Bergen International manufactures a variety of endothermic exothermic (endo/exo) blend CFAs for molding and extrusion applications.

Agent	Recomendations	Molding	Extrusion
Foamazol™ 84	Recommended for PVC and other low temperature thermoplastics requiring high weight reductions.

Foamazol™ 88	Intended for maximum density reductions at relatively low processing temeratures in either extrusion or injection molding.

XO-209	Intended for applications that require relatively high gas yields.

XO-234	A pelletized masterbatch for controlled gas release while still producing low density foams.

XO-272	A pelletized masterbatch for controlled gas release while still producing low density foams.

XO-408	pelletized masterbatch for use in PVC applications to produce controlled gas yields and obtain uniform cell structures.

XOP-266	Recommended for PVC and other low temperature polymers requiring high weight reductions.

XOP-308	A free flowing powder designed to provide a fine cell structure in most systems with emphasis on the endothermic end.

XOP-331	A free flowing powder designed for PVC to produce controlled gas yields and obtain uniform cell structure.

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
