EPS Polystyrene Sponge Granules for Construction Icf Polystyrene Blocks

Product Description

EPS (Expanded Polystyrene ) 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.

Application

Expanded Polystyrene with relatively low density (1.05g/cm3 ) ,low thermal conductivity ,low water absorption,impact resistencce,heat insulation  ,sound insulation,moistureproof,vibration damping  and  excellent dielectric properties,widely used in mechanical equipmemnt ,instruments and meters ,household electric ,crafts and other valuable products easilly damaged,shockproof packaging materials as well as the fast food  packaging.

Flame retardant EPS grades confer  excellent processingand product propertiesn Consistent raw bead and good fluidity of foamed bead Rapid expansion Relatively low density in second-time expansion.Excellent flame retardation with the US UL  Product Security Certification.Wide range of operation and suitablefor various block machines ,automatic ,machines and manual presses.Fine cell,beautiful and  flat appearance .Low shrinkag rate of  block in molding .Recommended 40-70 expansion ratio to increase  as  per  several-time  expansion.
