Chemical Foaming Agents for the Extrusion of PVC

Tramaco supply a wide variety of chemical foaming agents for the extrusion of PVC. The products are tailored to the specific requirements of the various applications in the PVC industry.

The foaming agent compositions are adapted both to the common foaming processes like free foam, Celuka, coextrusion etc., as well as to specific stabiliser systems. The microgranules of the TRACEL TSE and TRACEL® G masterbatch series are designed for continuous dosing operations. If no adequate dosing equipment is available the TRACEL® DB powder blend series are preferred for addition of the foaming agent to the dryblend.

Upon request our foaming agents can be supplied in customised preweighed meltable 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.
