Overview Polypropylene is a low cost, chemical resistant plastic with excellent aesthetic qualities. Polypropylene is easy to weld using thermoplastic welding equipment and is often fabricated into water and chemical tanks.

Polypropylene is available in both homopolymer and copolymer grades.

    Homopolymer Polypropylene

    Homopolymer polypropylene is stronger and stiffer than copolymer.

    Copolymer Polypropylene

    Copolymer polypropylene is a bit softer, but it is tougher and more durable than homopolymer polypropylene. Copolymer polypropylene tends to have better stress crack resistance and low temperature toughness than homopolymer polypropylene.
