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)

Electronic package,agriculture and fishery packaging vessel,thermal insulation,buoy,crafts,food and drinking container. For the production of rigid foam sheet and mouldings for applications involving exposure to pressure and moisture and so on.
1.Packing:
25kg/bag, or per your requirement.
17mt/20'FCL
2.Storage:
The EPS series products need to be put on the place where it is cool and ventilated, keep the storage temperature below 20°C in order to minimize the lost of frothing agents from escaping. The lower the temperature is, the better the quality is. The products should avoid rain, fog, snow and lighting up from the sun, static electricity and flame. Once the package material of the products is open, it should be used up as quickly as possible. Otherwise, the remaining EPS might lose its function due to escaping of foaming agents. If the EPS is stored too long, the expandable times might decrease.
3.Transportation:
During transportation, the product should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass. Transportation together with toxic, corrosive and flammable substance is strictly prohibited.
