PP (Polypropylene) PP (Polypropylene)

These are the properties of PP (Polypropylene), a material used in plastic bearings. Take a look at the characteristics of this material.

Overview of PP

PP stands for Polypropylene, a polymer produced by the polymerization of propylene. It has a low density, floats on water, and is resistant to chemicals. However, it has poor dyeability and only limited heat resistance.
