    Polypropylene (PP) is a polymer that shares some of the properties of polyethylene, but it is stronger, stiffer, and harder. It softens at higher temperatures, with a melting point of approximately 170 °C [340 °F]. PP retains mechanical and electrical properties at elevated temperatures, even in humid conditions and when submerged in water. It is slightly harder and more heat resistant than polyethylene. PP is a white, mechanically rugged material with high chemical resistance. It is sensitive to microbial attacks, such as bacteria and mold.
