EPS Factory Hot Sale EPS (Expandable Polystyrene) / White Polystyrene Powder/ EPS Resin with Good Price From Original Factory

E.P.S. (Expandable Poly-Styrene) is a lightweight, rigid, plastic foam insulation material produced from solid particles of polystyrene. Expansion is achieved by virtue of small amounts ofpentane gas dissolved into the polystyrene base material during production. The gas expands under the action of heat, applied as steam, to form perfectly closed cells of EPS. These cells occupy approximately 40 times the volume of the original polystyrene bead. The EPS beads are then molded into appropriate forms suited to their application. Products made from foamed polystyrene are nearly ubiquitous, for example packing materials, insulation, and foam drink cups.
Feature:
Good flame-retardant,
good frothing good preserving,
good binding and low heat-conducting rate.Oxygen index over 30 (testing after 7-14 days flowing)

EPS is a kind of lightweight polymer. It is the use of polystyrene resin added to the foaming agent, at the same time heating softening, gas production, forming a hard closed cell structure of foam plastic
