High quality EPS bead/expandable polystyrene EPS granules /EPS foam raw material factory price

High quality EPS bead/expandable polystyrene EPS granules /EPS foam raw material  Product Description expandable polystyrene EPS granules    E.P.S (Expandable Poly Styrene) is a lightweight, rigid, plastic foam insulation meterial produced from solid particle of polystyrene.
Expansion is achieved by virtue of small amounts pf pentane gas dissolved into the polystyrene base material during production.
The gas expands under the action of heat, applied as steam, to form perfectly closed ceils of EPS. These ceils occpy approximately
40 times the volume of the original polystyene bead     Specifications
