Use

Polystyrene is brittle at room temperature,becomes soft at 80°C, and is often modified bycopolymerization. Traditionally, it is used infilm form for capacitors, and it remains competitivefor this application. Polystyrene is alsoused for coaxial-cable insulation, but in woundstrip or bead form, because the solid is not veryflexible.Poly(styrene) is white powder or beads, or clear solid poly styrene: A clear glasslike materialmanufactured by free-radicalpolymerization of phenylethene(styrene) using benzoyl peroxide asan initiator. It is used as both a thermaland electrical insulator and forpacking and decorative purposes.
