What is the difference between Polypropylene Copolymer and Polypropylene Homopolymer?

The main difference between Polypropylene Copolymer (PPC) and Polypropylene Homopolymer (PPH) lies in their chemical structure. PPH is made from a single monomer (propylene), resulting in a stiffer, stronger, and more chemically resistant material with a higher melting point. Whereas, PPC is made from 2 or more monomers (propylene and another like ethylene), which leads to increased flexibility, impact resistance, and toughness, but with a lower melting point.
