Chemical Foaming Agents for Rotational Moulding of PE

In rotational moulding of PE the use of foaming agent powders is preferred. These powders are fed to the mould together with the polymers. To improve the foaming characteristics in rotational moulding, special foaming agent compounds have been developed that are predispersed in a PE carrier system.

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.
