POLYSTYRENE
- Polystyrene is a thermoplastic resin which is manufactured from the
polymerization of styrene
monomer. There are two basic
grades, crystal or unmodified general purpose polystyrene and impact
or rubber modified polystyrene. The crystal polystyrenes possess high
rigidity, gloss, and transparency (clarity) but have
limited impact or toughness properties. Impact grades are generally
(opaquel but have improved impact resistance and environmental stress crack
resistance due to rubber modification
