What is a granule? The granule is not a specific polymer. It is a kind of polymer structure called granules, which is a granular structure used in the production of many plastic materials.
In other words, it is a form of polymer obtained in petrochemicals that is granular and must be melted and used for applications and applications.
In fact, when the polymer is produced, it is melted in the extruder (something like a meat grinder) and the extruder head cuts off a cutter or whatever like that polymer and produces granules.
