PS

Polystyrene (polystyrene). Thermoplastic resin obtained by poly-addiction of styrene.
 
There are several types of this material, like:
 
  • PS (crystal) homopolymer amorphous, transparent
  • HIPS (impact resistant) modified with rubber
  • EPS (expandable) pentane is used as an expandable agent
  • XPS (expanded) expanded and extruded
  • BOPS (bioriented) bioriented leaf
 
Features and applications of the virgin material
It shows no crystallization and its high fluidity makes it very workable. Well resistant to stress but it has low impact resistance; it’ a good electrical insulator and among other polymers reacts much better to weather agents. Polystyrene is generally used for the production of food packaging, appliances, furniture, toys, musical instruments, syringes.
