EPS- Expanded Polystyrene

Sperry Plast is one of the leading manufacturers of rigid foam products for protective packaging purposes. Known for our superior quality, service and innovation, we custom manufacture products for a diverse group of customers, and our experienced design consultation staff is regularly working on prototypes for new customers and applications.

Whether it’s ultimately manufactured through our sophisticated molded or fabrication processes, we work closely with our clients from the 3-D modeling concept stage, through prototype development, to final approval and delivery. We utilize various types of rigid foam to develop the ideal solution for the specific need.

Expanded Polystyrene (EPS) is a rigid cellular from of polystyrene with excellent thermal insulation and shock absorbing properties, high compressive strength, very low weight and resistance to moisture. The properties of EPS have many applications in the construction and packaging industry.

The state of the art plant of EPS molding is setup in 2010, equipped with the latest imported machinery and molds the plant is spread over an area of 11500 sq mts.  The plant has fully automatic vacuum cooled machines of all  sizes have a very high production capacity and quality consistency. The unit has twenty machines range from 1400mm to 1750 mm frame size unit with an annual capacity of 300 tons per month.  The production is ISO 9001:2008 certified.
