Expanded Polystyrene

Expanded polystyrene (EPS) is a generic term for polystyrene and styrene copolymers that are expanded into a variety of useful products. Expanded Polystyrene is a rigid lightweight thermoplastic with closed cell construction.

EPS is supplied to molders in the form of a polystyrene bead; EPS beads are loaded with a blowing agent, usually pentane, and other chemical agents and additives that give the beads expansion vibrancy and allow them to be processed and molded into low-density foam articles; EPS is comprised of 90 percent air. The shock absorbing properties and other qualities of EPS foam, combined with its low-cost, high insulating properties, custom moldability and ease of processing make it a popular packaging material.

Did you know that Expanded Polystyrene is recyclable? In fact Davis Core & Pad is part of the Alliance of Foam Packaging Recyclers, which has more than 200 collection sites in the U.S. and Canada. And due to polystyrenes resiliency it can be recycled over and over again. EPS beads are usually loaded with pentane instead of CFC'
  • No Chlorofluorocarbons (CFCs) have ever been used in the manufacture of expanded polystyrene transport packaging.
  • Polystyrene represents a tiny fraction - less than one percent by weight - of the solid waste stream.
  • Davis Core and Pad has implemented a formal quality system based on ISO 9000:2000 standard. Our Quality System is in place to assure our customers of the quality performance that we have maintained for many years. A process which begins with the original inquiry for packaging design and extends to your end use of our products.
