Universal Plastics sources the highest quality materials from our extensive network of leading suppliers within the industry. A selection of the most commonly used blow molding materials are listed below.

  • HDPE (High Density Polyethylene): Excellent impact and chemical resistance. Good cold temperature properties. Dimensionally not as stable as other materials.
  • PP (Polypropylene): Excellent chemical resistance. Rigid, with very good impact strength. Good at higher temperatures. But dimensionally not as stable as other materials, similar to HDPE.
  • PETG (Polyethylene Terephthalate Glycol): Clear, with excellent impact strength. Forms well.
  • PC (Polycarbonate): Very high impact strength. Clear. High temperature resistance.

Other specialty materials are available. We have extensive experience using a variety of plastic materials with unique properties and characteristics.
