Polystyrene Plastic Used in Injection MoldingPolystyrene Water Bottles

One of the most common plastics used in thermoplastic injection molding is polystyrene, a synthetic polymer often used when molding packaging and industrial components. Usually in the form of foam or plastic, polystyrene is a non-toxic and odorless material and is one of the predominant plastics used in the food packaging industry as well as the automation industry. Its solidity and clarity make it useful for everything from automobile parts and electronics to toys and plastic utensils.

Polystyrene is often used in cost-effective packaging products since it has many benefits, including:

  • Resistance to bacterial growth
  • Resistance to moisture
  • Lightweight
  • Provides insulation
  • Durable
  • Recyclable

Polystyrene is used for a wide variety of purposes, and the professionals at Retlaw Industries manufacture products such as idler pulleys, adapters, sprockets, and rebar chairs for industries all over the United States. We will mold your part out of polystyrene, or any type of plastic you need it in – contact us today to get a product quote on your thermoplastic components.
