AC 300 Static Dissipative Acrylic

AC-300™ Acrylic is a plastic sheet product designed to control static electricity for a wide range of end uses. It is a premium quality acrylic sheet which has been surfaced with a clear C-300™ static dissipative surfacing. This unique technology prevents charge generation on the sheet surfaces, thereby controlling particulate attraction and preventing electrostatic discharge (ESD) events. This performance is permanent and totally independent of humidity. AC-300™ Acrylic offers exceptional design versatility since it fabricates simply, is light in weight and is available in large sheet sizes. AC-300™ also exhibits excellent optical properties, chemical resistance, surface hardness, and mar/scratch resistance.

AC-300™ Acrylic is easily fabricated into flat surface configurations using the same equipment and fabrication techniques generally employed with unsurfaced acrylic sheet products. It should not be used for heat-formed bent configurations since the hard, cured C-300™ surface is not designed for heat bending. When solvent welding, it is necessary to remove the C-300™ surface mechanically to achieve a good bond. 

Trim fluid can be used on glue lines in items fabricated from ESd sheets to provide electrical continuity across the glued joints.


  • Cannot be tribocharged when properly grounded
    Prevents build-up of static charge and accumulation of harmful contamination.
  • Electrostatic decay in less than 0.05 second per Federal Test Standard 101C, Method 4046.1
    Results in rapid static dissipation without arcing.
  • Surface resistivity of 106 - 108 ohms per square
    Provides for ESD control without the need for ionization.
  • Permanence in static dissipation performance
    Avoids the cost of application of temporary topical anti-stats.


  • Covers, windows, doors, and access panels for electronic equipment
  • Machines and instruments
  • Fabricated desiccators, cabinets, and boxes
  • Transparent room partitions and pass-thru modules
  • Process equipment enclosures and mini-environment glazing panels

    The product also has many general industrial uses, including protection for static charge sensitive manufacturing devices and control of spark discharge in explosive environments.
