EXPANDABLE POLYSTYRENE Expandable Polystyrene (EPS) is polystyrene containing a blowing agent (Pentane) and comes in the form of beads. It has thermal insulating, impact resistance and good process ability. Therefore, it is widely used in Thermal Insulation, Packing Materials and misc. special applications. In addition to the general EPS grade which is used for Insulation blocks & panels, packaging application, drinking cups, food boxes, pipe insulations, ice boxes, shock absorbers etc. we also produce Flame Retardant (FR) EPS that is used specifically in the insulation industry.
