| The HYDROCEROL PEX Series is specially developed for Packaging EXtrusion applications where thermoforming characteristics of the finished film are a key issue. PEX Series foaming agents produce an especially fine-celled foam structure, enabling thermoforming without surface defects. Density reductions between 15 to 30% are usual in standard monolayer as well as in co-extruded (e.g., A-B-A) applications. HYDROCEROL PEX formulations are available for most common packaging resins, such as PP, PE, PS and PET. |
