Expandable Polystyrene For EPS Foam Helmet

Update::2020-12-29 15:16 View:
    EPS(Expandable Polystyrene) is a lightweight, rigid, plastic foam insulation material produced from solid particles of polystyrene. Expandsion is achieved by virtue of small amounts of pentane gas dissolved into the polystyrene base material during production.The gas expands under the action of heat, applied as steam, to form perfectly clesed cells of EPS.

How do we classfiy EPS Material?
