EPS(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 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 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.
E-standard grade material is a widely used ordinary EPS, suitable for automatic vacuum forming machines, electric drive forming machines, and traditional lifting hydraulic presses. It is a standard foaming ratio raw material, which can be foamed to achieve lighter density foams at a time. Generally, it is more suitable for products with a foaming rate of 13 g/l or more. It is widely used in electrical packaging, thermal insulation materials, and fishing floats. , Handicrafts, decorations, lost foam castings, etc.
