Plastic particles are raw materials for storing, transporting and processing plastics in the form of semi-finished products. Plastics are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be produced from petroleum. The molecules of these substances can react with each other under certain conditions to form compounds with large molecular weight, namely polymers.
The most prominent property of polypropylene is its versatility, which is suitable for many processing methods and uses. Its value and versatility mainly come from its excellent chemical resistance, the lowest density and highest melting point among all thermoplastics, and moderate cost. The difference between polypropylene (PP for short) and polyethylene PE is that the former has a methyl group on every other carbon atom, which serves to harden the chain. Unless these methyl groups are on the same side of the chain, the polymer will not crystallize.
