Static Dissipative Acrylic Data Sheet – ESD/Cleanroom Properties for Acrylic Material
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:
- Acrylic plastic is a combustive thermoplastic. Avoid exposure to flame and excessive heat. Observe fire precautions appropriate for comparable forms of wood and paper.
- Clean with soap and water. Do not use abrasives. Avoid inappropriate contact with solvents.
