Polypropylene random copolymers are created by modifying the fundamental structure of polypropylene with another monomer molecule. The most common monomer used is ethylene. In the polymer chain, ethylene molecules are introduced at random between the propylene molecules. The addition of ethylene alters the physical properties of polypropylene.<br><br>Random copolymer polypropylenes are used in blow molding, injection molding, and extrusion molding applications that require improved clarity and dimensional stability. They're found in medical packaging, food packaging, and consumer goods.
