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.
