DESCRIPTION AC-300™ and AC-350™ Cast Acrylics are premium quality clear cast acrylic sheet materials which have been surface coated with SciCron Technologies' STATICON® proprietary, clear, static dissipative surfacing. This unique technology imparts to the sheet surfaces superior resistance to charge generation and superior static decay performance. The result are sheet products which exhibit excellent control of both electrostatic discharge (ESD) and particulate attraction. These characteristics are permanent and totally independent of humidity.
ANTISTATIC ACRYLIC GRADES AC-300™ Cast Acrylic
AC-300™ is easily fabricated into flat surface configurations. It should not be used for heat-formed bent configurations. AC-300™ is manufactured from premium quality cast acrylic sheets which is optically virtually distortion free. Consequently, it is widely used in clean rooms by the semiconductor, electronic, micro-manufacturing, pharmaceutical, and biomedical industries. Applications include; perimeter windows, transparent room partitions, light-weight floor-to-ceiling window walls, laminar-flow air containment screens, mini-environment glazing panels, pass-thru modules, equipment enclosures, and desiccator cabinets.
AC-350™ Acrylic
AC-350™ is designed to accommodate heat bending when heat temperatures are carefully controlled. Typical applications include heat-formed covers, windows, doors and access panels for electronic equipment, machines and instruments, and formed enclosures including protection of static-sensitive devices and spark discharge control in explosive environments.
AVAILABILITY AC-300™ and AC-350™ are available in standard full-size sheets of 1/8, 3/16, 1/4, 3/8 and 1/2 inch thicknesses by 4 ft. wide by 8 ft. length. Cut-to-size pieces are available. Metric sheet thicknesses are available by custom quote only (minimums may apply).
FEATURES AND BENEFITS
