What is EPS?

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. These cells occupy approximately 40 times the volume of 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.

EPS Raw Material Storage



EPS contains volatile and combustible composition and should therefore be kept far away from any 

source of ignition, perferable in a cool, dry and well-ventilated storeroom below 25 ℃ out of direct 


The effective shelf life is 3 months at the temperature blow 25 ℃, however the ideal material should be

used within 1 month from manufacturing. Once the package is unfolded, the blowing agent will be

volatilized rapidly. EPS should be therefore used immediately after bags opened to avoid the reduction

of expansion ratio or losing effectiveness.

Reasonable weight loss: EPS contains high-volatility blowing agent(C5). It is therefore normal to lose

weight in the first half month after the product leaving the factory.
