Polystyrene Vs. Polypropylene: Key Differences And Applications
Chemical Structure Polystyrene: Aromatic hydrocarbon polymer with benzene rings as side groups. Polypropylene: Aliphatic hydrocarbon polymer with only carbon and hydrogen atoms. Physical Properties Polypropylene is denser, stronger, harder, stiffer, and more thermally conductive than polystyrene. Polystyrene is more transparent and has lower electrical resistivity. Transparency and Biodegradability Polystyrene is transparent, while polypropylene is translucent….
