Lightweight PP Face Shields Raw Plastic Granules PP Plastic
Granules
PP granules are small pieces of thermoplastic resin made from
polypropylene polymer. They are widely used in injection molding,
blow molding, and extrusion processes to produce a variety of
products due to their cost-effectiveness, lightweight, chemical
resistance, and moisture resistance properties.
