Chemical Foaming Agents for Engineering Polymers
Engineering polymers need special chemical foaming agents due to their properties. For
example polycarbonate is degraded by the decomposition products of all chemical foaming
agents except 5-phenyltetrazole (Unicell 5PT).
Tramaco have developed a special range of products for performance polymers.
Our Technical Service Department will be glad to help you choose the best product from our
range for your application. Please use our contact form for your enquiries.
