Polystyrene is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapor and has a relatively low melting point.
General purpose polystyrene (GPPS) is one of the most widely used kinds of plastic that has excellent transparency, high stiffness and excellent moldability (injection, extrusion, foam molding, etc.).
Relatively low-cost material used in production of disposable consumer products, colored easily to produce solid or transparent tints and not hygroscopic- so there is no need to dry.

HIPS is amorphous thermoplastic material, an opaque or translucent rather than transparent polymer, used in lower heat applications
Superior impact strength, improved resistance to stress cracking and to crazing caused by organic liquids, oils & fats.

|Food packaging trays
A rigid, closed cell, thermoplastic foam material produced from solid beads of polystyrene, which is polymerised from styrene monomer and contains an expansion gas (pentane) dissolved within the polystyrene bead. EPS is ideal for the packaging and construction industries due to its light weight, strong and excellent thermal insulation properties.
Highly resistant to biological corrosion, minimizes the effect of moisture and water vapour, and good shock absorption.
