Polypropylene is a very common material molded at Fort Wayne Plastics. Polypropylene resin is regularly utilized in both low pressure, multi-nozzle, structural foam and gas assist structural web injection molding process formats. Polypropylene is widely used in returnable material handling products, medical applications and many other product applications that require toughness.

Polypropylene is a commonly recycled material and is recognized with the number “5” as its recycling identifier.

Polypropylene Plastic Properties:

At higher temperatures, PP is resistant to stress and cracking, as well as chemical solvents, bases, and acids. Standard polypropylene has a melting point of 320°F (160°C) and possesses an outstanding balance of mechanical properties, melt flow, color stability, and moisture barrier properties.
