Die plates for the pelletizing of plastics.
(Dutch, French, German)

Polymerisation of ethylene and propylene produces polyethylene (PE) and polypropylene (PP) as a powder. This powder is processed into granulate or pellets by means of an extruder equipped with a die plate. John Düring and Roel Jochems have written an article on the latest developments in the field of die plates. These are essential for the quality of the pellets.
