AC-300 / AC-350
Anti-Static Acrylic Sheet Specification

( see also Standard Acrylic Specifications )
( see also AntiStatic Polycarbonate and AntiStatic PVC Specifications )
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
  • Cannot be tribocharged when properly grounded - prevents static buildup
  • Electrostatic decay in less than 0.05 second per Federal Test Standard 101C, Method 4046.1 (rapid dissipation without arcing)
  • Ideal surface resistivity without need for ionizers or coatings
  • Permanence in static dissipation performance without periodic re-coating
  • Humidity-independent static charge control
  • Advanced technology, uniform surface treatment avoids "hot spots"
  • Superior fabrication characteristics offer simplified design and installation
  • Inherently light-weight material with large sheet availability
  • Superior chemical resistance with reduced risk of solvent attack
