Polystyrene Resin

Polystyrene Resin (PS) is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene.Ps Resin can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. Resin Polystyrene is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year.Polystyrene can be naturally transparent, but can be coloured with colourants. Polystyrene Resin Powder uUses include protective packaging (such as packing peanuts and in the jewel cases used for storage of optical discs such as CDs and occasionally DVDs), containers, lids, bottles, trays, tumblers, disposable cutlery,in the making of models, and as an alternative material for phonograph records.

As a Rubber And Plastic, polystyrene is in a solid (glassy) state at room temperature Sodium Hexametaphosphate but flows if heated above about 100 °C, its glass transition temperature. It Titanium Dioxide becomes rigid again when cooled. This temperature behaviour is exploited for extrusion (as in Styrofoam) and also for molding and vacuum forming, since it can be cast into molds with fine detail.
