Acrylic vs. Static Dissipative PVC

Static Dissipative PVC 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. 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 Plating is made from PVC with 2 durable non-outgassing static dissipative layers

  • Revolutionary Static Dissipative PVC Plating renders acrylic-made products obsolete for any static or particle-sensitive application
  • Chemically embedded dissipative layers maintain a surface resistivity of about 107 ohms/square, even under real-world abuse
  • Ideal for cleanroom use effective static dissipation helps control particulate contamination by eliminating static attraction
  • Transparent material allows complete visibility
  • Also resists a wide range of corrosive chemicals and will not outgas

Characteristics
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. 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.

Applications
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:
