E.P.S. (Expandable Poly-Styrene)
is a light weight, 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
processing method of EPS can be divided into mode method and extrusion method according to different foaming ways. This uniform closed cavity structure makes EPS have the characteristics of small water absorption, good thermal insulation, light weight and high mechanical strength.
The Application Of
EPS
has also been used for a large number of decorative materials, film and television scene layout, character modeling, marine life jackets and buoys. In particular, large foam sheet market demand is very large, as color steel sandwich panel, steel (board) grid composite light panels, wall outside the paste board, roof insulation boards and geothermal panels, it is more widely Used in the field of housing construction, for insulation, heat insulation, waterproof and moisture-proof materials on the ground.
