Expanded polystyrene:

Barnes Plastics are specialists in shape moulding and hot wire cutting of expanded polystyrene (EPS). EPS has very useful characteristics that make it ideal for many applications in packaging, building & construction, void filling, decorative features and display items.

Environmentally friendly:

  • Expanded polystyrene does not contain any ozone depleting substances and none is used in its manufacture.
  • Expanded polystyrene is able to be recycled. EPS can be granulated for use in construction applications or blended to make a range of every day plastic products including cassette casings and coat hangers
  • Burning EPS produces the same gases as that of burning pine...
