Polystyrene (PS) is a thermoplastic designed for applications requiring excellent electrical and mechanical properties together with good processability. Polystyrenes have well-balanced physical properties and are generally transparent, but available in various colors.

Royalstat™ R675 is a unique high impact polystyrene alloy that is electrically conductive. It meets the minimum static decay requirements outlined in MIL-B-81705C and NFPA Code 99 specifications and combines good stiffness, toughness and thermoformability with excellent electrostatic discharge (ESD) protection. Available in roll stock in thicknesses from 0.012″ to 0.025″ with a tolerance of ± 0.002″, ROYALSTAT™ R675 sheet assures excellent performance on an in-line thermoformer and automatic chip placement systems. In thicker gauges (0.030″ – 0.250″), R675 has excellent deep-draw characteristics.
