Compared to acrylic, static-dissipative PVC offers three benefits that reduce operating expenses and drive down overall ownership cost of a clean room, glove box, hood, desiccator, or other enclosure. 
An aseptic environment requires frequent sterilization with disinfectants such as alcohol. Unfortunately, most common biocides, including industry-standard IPA solutions, degrade acrylic, causing cracks and discoloration.
Acrylic’s most serious hidden cost becomes apparent when static-sensitive materials are destroyed or degraded by unpredictable electro-static discharge (ESD). 
In Stock Plastic Sheets
Available in 3mm, 4mm, 6mm, 10mm. Transparent, colorless, standard sheet size of 4' x 8' (1219 mm x 2438 mm)—other sizes are available on a custom basis. Both surfaces of the sheet are covered with masking paper for protection during shipping, and one or more sheets are packed per carton and then in a wooden crate.
This revolutionary material offers a new alternative to standard methods of static control in the cleanroom, lab, and other industrial environments. Like acrylic, it can be easily worked and offers great visibility, yet it also resists a wide range of chemicals (see chart). It is completely noncontaminating, and so can be safely used in the cleanest work environments.
The solvent of the static-dissipative dielectric coating melts the plating and mixes with the coating material so that the mixture adheres to the plate top. Both materials are mingled in the coating process. The coated material has great adhesion power and never comes off. The electrical characteristics are not affected by rubbing, and the transparency remains unchanged for long periods with little or no fogging.
Static-dissipative PVC features surface resistance between 106 and 108 ohms/square—much less than that of other treated plastics. Tests show that when 10KV is applied to the surface, electrostatic potential remains less than 15V, and static decay time is less than 1 second. And because this plating offers such effective static dissipation, it will not attract dust or other contaminating particles that could damage sensitive microelectronic components.
In a test conducted in accordance with ASTM D 257, both colorless and colored transparent plating sheets were subjected to a relative humidity of 20-80% at 10°C to 30°C and the samples exhibited almost no change in physical characteristics. The surface resistivity remained greater than 107 ohms/square.
This plating is also durable. It features superb resistance to UV radiation; tests have indicated almost no loss of static protection after 500 hours of continuous exposure to a fadeometer. In temperature tests, it maintained its dissipative properties after 50 cycles of temperature fluctuations from -20°C to 60°C. It is also completely noncombustible.
It also offers all of the chemical-resistance of standard PVC plating. It remains unaffected by a wide range of chemical solutions (see chart). In the case of mixed chemicals, resistance can vary widely depending on the exact mix. Be sure to perform a test prior to using any new chemical solutions or mixtures.
This plating allows easy cutting, bending, welding, and adhesive joining, and is therefore ideal in many situations for which no suitable material currently exists. Just consider these possible applications:

The effect of surface abrasion is very small and produces almost no change in the material’s antistatic characteristics.
Even when temperature or humidity vary, this material’s antistatic properties exhibit almost no change, and this excellent feature is stable over the long term.
