Polystyrene is an amorphous material with low moisture absorption and is one of the most commonly used plastics. It is crystal clear, hard, rigid and brittle and enables components with a high surface gloss. Areas of application include packaging, household goods, lighting technology and technical parts in general. The sensitivity to stress cracking and UV stability must be taken into account when using this material.
Polystyrene has a high resistance to acids, alkalis, and alcohol, but it is attacked by many non‑polar solvents. Its susceptibility to stress cracking and its limited UV stability should also be taken into account.
Typical applications include packaging, household goods, lighting technology, and general technical components.
