Chemical Foaming Agents for Rubber

In the production of foamed rubber parts an optimum dispersion of the chemical foaming agent in the polymer matrix is even more important than in plastics processing. Therefore foaming agent powders coated with dispersing agents or foaming agents predispersed in EPDM are preferred.

Upon request all our foaming agents can be supplied in preweighed sachets.

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.
