Polypropylene was first discovered in 1951 yet commercial mass production begun in late 1950's. It is one of the most versatile thermoplastics commercially available. It has good chemical and fatique resistance. It also has less density and better temprature resistance compare to HDPE. On the other hand, Oxidative degradation is accelerated by contact with copper. Polypropylene is used for coaxial cables, core insulation of control and data transmission cables, power cables, etc.
