Conductive polystyrene (PS-ESD)

WCI PS-ESD compounds are specially engineered polystyrene grades with electrostatic discharge (ESD) properties, designed to prevent static build-up and safely dissipate charges. These materials retain the core benefits of polystyrene — light weight, rigidity, transparency, or impact resistance depending on the base grade — while delivering controlled surface resistivity in the range of 10⁷–10⁹ Ω/sq.

WCI offers PS-ESD grades based on different PS families to meet diverse requirements:

• EPS-ESD: Lightweight, foamed, and insulating with added ESD protection.
• GPPS-ESD: Transparent, rigid, and easy to process with dissipative properties.
• HIPS-ESD: Toughened and impact-resistant for functional ESD-safe components.

Together, these grades enable safe, reliable, and cost-effective solutions for electronics packaging, protective housings, and thermoformed trays used in sensitive applications.
