Title: METHOD FOR PRODUCING EXPANDED THERMOPLASTIC POLYMERS
Abstract:
An improved process for fabricating expanded thermoplastic polymers (eTP) starting from non-expanded TP is disclosed whereby said process has improved thermal control, uses preferably environmentally friendly foaming gasses, avoids anisotropy and sticking of the eTP during the processing and minimises the duration of the charging step.
