PMMA Cast Acrylic ESD is easily fabricated into flat surface configurations. It should not be used for heat-formed bent configurations. PMMA Acrylic ESD 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.

Characteristics:
- 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 10^6 to 10^8 ohms per square – Provides for ESD control without the need for ionization.
- Permanence in static dissipation performance – Avoids cost of application of temporary topical anti-stats.
- Humidity independent static charge control – Avoids inconvenience of maintaining high levels of humidity and damage caused by such humidity.
- Advanced technology, uniform surface treatment – Avoids conductive discontinuities (charged “hot spots”) often found with non-uniform temporary topical anti-stats.
- Excellent optical properties – C-300 surface provides excellent clarity for optimum use of available light.
- Superior chemical resistance- Reduces risk of solvent or chemical surface damage.
- Hard, mar resistant, durable surface – C-300 surface, harder than the base plastic, reduces risk of damage to the sheet surfaces.
- Superior fabrication characteristics – Results in optimum workability during part fabrication.
Limitations
- Limited Chemical Resistance to Hydrofluoric Acid, Acetone, Methyl Chloride
