About Bergen International

Bergen International, founded in 1999 and headquartered in Elgin, Illinois, USA, specializes in polymer additives for the plastics industry. The company produces chemical foaming agents (CFAs) and nucleating agents compatible with polymers such as polyolefins, styrenics, engineering resins, and PVC. Its additives are used in injection molding, extrusion, rotational molding, structural foam, and wire & cable applications. Available as powders, pellets, and liquids, these products enhance processing efficiency, reduce polymer usage, improve surface finish, and strengthen foamed and molded parts. Bergen International also provides custom formulations and technical support to optimize polymer performance.

Foamazol™ 73 S

Foamazol™ 73 S by Bergen International is a chemical foaming agent. It is characterized by endothermic decomposition. It is used in injection molding and extrusion applications where fine and uniform cell structure is required. It is recommended for nucleation of direct gassed polystyrene foams. Maximum gas yields are achieved when processing temperatures of 185- 230°C ( 365-446°F) are reached. Usage level of injection molding is 0.5- 2.0%.
