PP PE two plastic particles descriptionPP is polypropylene, which can be divided into isotactic polypropylene, syndiotactic polypropylene, Zhi random polypropylene, propylene ethylene random copolymer, propylene ethylene block copolymer, grafted polypropylene, chlorinated polypropylene, metallocene polypropylene and so on. It can be divided into extrusion stage, drawing stage, coating stage, injection stage, film stage and so on.
PE is polyethylene, mainly including low-density polyethylene, high-density polyethylene, linear low-density polyethylene, metallocene polyethylene, ultra-high molecular weight polyethylene, cross-linked polyethylene, chlorinated polyethylene, etc. It can also be divided into extrusion stage, drawing stage, coating stage, injection stage, film stage and so on.
Polyethylene and polypropylene are both petrochemical products. What you said should be recycled plastics. Recycled polyethylene and recycled polypropylene are mainly classified according to their uses. For example, after recycling and granulating of plastic waste woven bags, it is drawing grade polypropylene, while after recycling and granulating of plastic pots, barrels and other products, it is injection grade.
