Polystyrene is a polymer produced by polymerisation from the monomeric phase. It is derived from petroleum. It is mostly used with PS abbreviation in plastic industry. At room temperature, the polystyrene is a thermoplastic in solid form, but it is melted at high temperatures when processed by injection or extrusion. Then it is solidified again by cooling process.
Physical and Chemical Properties
Recycling code is 6. The density ranges from 1.03-1.06 g / ml. The maximum temperature resistance is 70 ° C. It is a multi purpose plastic that can be rigid and foam. Very hard, fragile and bright. It is a very inexpensive resin with a relatively low melting point. The polystyrene burns fast, emits strong gas odor, and produces a considerable amount of soot. Rapidly blister in an acetone environment. Good resistance to UV rays, good impact and tensile strength, low price and ease of processing. Also it shows superior resistance to acid alkali and salts.
