What Are ESD Polycarbonate & Acrylic Sheets?
ESD polycarbonate and acrylic sheets are engineered plastic panels with a permanent anti-static coating that prevents static charge accumulation on the surface. Unlike standard plastics, which can generate and hold static electricity (tribocharging), ESD sheets safely dissipate static charges when properly grounded, protecting sensitive electronic components from electrostatic discharge (ESD) damage.
At VIIST, we apply the anti-static functional coating in-house — ensuring uniform surface treatment with no conductive discontinuities or ‘hot spots’ commonly found in inferior products. Our ESD sheets are then precision-fabricated according to your drawings, available as semi-finished parts (OEM components) or fully assembled finished products.
