Chemical Foaming Agents for Injection Moulding of PVC
Chemical foaming agents for the injection moulding of PVC are mainly powders that are
added in the compounding step, although some granular masterbatches and expandable
microspheres are used too. Tramaco supply a range of products tailored to specific
applications and resulting in different foaming characteristics and cell structures.
