Acrylic Sheet, AC-350™ Static Dissipative (Bending Grade)

AC-350™ is a static dissipative acrylic sheet engineered specifically for heat-formed parts, carrying a permanent C-350™ dissipative surface with a surface resistivity of 10⁶–10⁸ ohms per square for reliable ESD control without ionization. Where standard dissipative grades are limited to flat panel work, AC-350 is formulated to survive the bending process — the dissipative surface stays intact through line bending and forming, so fabricators can produce covers, hoods, and enclosures with formed radii instead of building them from bonded flat panels. It delivers 80% total light transmittance at 3mm with less than 3% haze, and the dissipative properties are permanent and humidity-independent rather than a topical treatment that washes off.

AC-350 is specified for formed covers, windows, doors, and access panels on electronic equipment, machine hoods and guards, workstation shields, component handling fixtures, and process enclosures throughout semiconductor, electronics, and micro-manufacturing operations. Standard thicknesses are 3mm (1/8"), 4.5mm (3/16"), 6mm (1/4"), 9mm (3/8"), and 12mm (1/2") in 48" x 96" sheets, with 9mm and 12mm available in cell cast form. Maximum continuous service temperature is 180°F, with a deflection temperature of 210°F at 264 psi. One fabrication note that matters: apply heat carefully during bending — excessive heat will damage the C-350 surface and compromise the dissipative performance the part was specified for.
