Bergen International’s objective is to focus solely on chemical foaming agents -- offering endothermic, exothermic and endo/exo blends compatible with most of the polymers used in foaming applications.

Founded in February 1999, Bergen International was created by former employees and agents of a major chemicals company that was a leading manufacturer and supplier of chemical foaming agents for the plastics industry.

The company’s staff has extensive experience in the plastics industry with strong emphasis in the development of foams.

Bergen is dedicated to building a strong customer base with its versatile product line...development of new chemical foaming agent products...and outstanding customer service.

Our Foamazol™ chemical foaming agent product line of powders, masterbatches and liquids is manufactured in the U.S. and distributed by sales agencies and representatives in the U.S., Canada, Mexico and Europe.

In the future, we plan to begin additional manufacturing overseas for our European customers.
