Static Dissipative Acrylic Data Sheet

Static Dissipative Acrylic Data Sheet – ESD/Cleanroom Properties for Acrylic Materialacrylic desiccator storage cabinets
TDI Static Dissipative Desiccators and Gloveboxes

Static Dissipative Acrylic Data Sheet for Material used on our Desiccators & Gloveboxes

FEATURES AND BENEFITS:

  • 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.
  • The surface resistivity of 106 – 108 ohms per square. Provides ESD control in a wide range of applications.
  • Permanence in static dissipation performance. Avoids high maintenance cost of periodic application of temporary topical anti-stats.
  • Amine free, humidity independent and does not outgas under normal operating conditions.
  • Excellent optical properties. C-300 surface provides excellent clarity for optimum use of available light.
  • Superior chemical resistance. Reduces risk of solvent and chemical damage to the static dissipative surface.

PRECAUTIONS:

  1. Acrylic plastic is a combustive thermoplastic. Avoid exposure to flame and excessive heat.  Observe fire precautions appropriate for comparable forms of wood and paper.
  2. Clean with soap and water. Do not use abrasives. Avoid inappropriate contact with solvents.
