What is Polypropylene?

Polypropylene machinable plastic, or Polypro for short, is a rugged, light weight, abrasion resistant, and high strength thermoplastic. Polypropylene plastic is also good at transporting moisture and extremely resistant to many chemical solvents, bases and acids.

It is a cost-effective material with excellent aesthetic qualities; easy to weld using thermoplastic welding equipment; and is often fabricated into water and chemical tanks.

Homopolymer polypropylene is stronger and stiffer than copolymer. Copolymer Polypropylene is slightly softer, but tougher and more durable versus homopolymer.

Fluted Polypropylene has a wide variety of industrial, artistic, and decorative applications.

Polypropylene and fluted polypro plastics are also known by brand names including Proteus, Protec, Polystone, and Propulux.
