Polystyrene – PS

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.

GPPS(General Purpose Poly Styrene

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.).

Benefits

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.

Applications

Injection MoldingCase for lunch box, confectionary tray,CD cases
ThermoformingDisposable items

HIPS(High Impact Poly Styrene)

HIPS is amorphous thermoplastic material, an opaque or translucent rather than transparent polymer, used in lower heat applications

Benefits

Superior impact strength, improved resistance to stress cracking and to crazing caused by organic liquids, oils & fats.

Applications

ExtrusionThick sheet for light panel
Injection MoldingCutlery, laptop casings, CD/DVC covers, pens lid , hangers
ThermoformingFood packaging trays

EPS(Expanded Poly Styrene)

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.

Benefits

Highly resistant to biological corrosion, minimizes the effect of moisture and water vapour, and good shock absorption.

Applications

Electronic GoodsCushioning & packaging
Thermal InsulationThermal boards in building constructions and packaging products
