Static Dissipative Plastic

Description
PC-350™ Polycarbonate is a plastic sheet product design-ed to control static electricity for a wide range of end uses. It is a premium quality polycarbonate sheet which has been coated with SciCron Technologies proprietary, clear, C-350™ static dissipative coating. This unique technology prevents charge generation on the sheet surfaces, thereby controlling particulate attraction and preventing electrostatic discharge (ESD) events. This performance is permanent and totally independent of humidity. PC-350 Polycarbonate offers exceptional design versatility since it fabricates simply, is light in weight and is available in large sheet sizes. It also exhibits excellent clarity and chemical resistance, plus superior impact resistance, flame spread properties, and bending characteristics.

Applications
PC-350 Polycarbonate resists tribocharging under all circumstances and cannot generate a charge when properly grounded. This makes it ideal for use in manu-facturing and assembly operations for charge sensitive electronic components where it can help prevent both immediate and latent ESD caused defects. Since it resists charge build-up it does not attract contaminants, so it can also help prevent contamination-related rejects in ultra-clean manufacturing operations. Consequently, it is suitable for use in the semi-conductor, electronic, micro-manufacturing, and mining industries. Typical applications include contoured panels and fabricated items which require heat bending, such as; guards, covers, windows, doors, and access panels for electronic equipment, keypads, assembly machines and instruments; conveyor line covers and shields; and equipment enclosures. The product also has many general industrial uses, including protection for static charge sensitive manufacturing devices and control of spark discharge in explosive environments.

Fabrication
PC-350 Polycarbonate is easily fabricated into a variety of flat and bent configurations using the same equipment and fabrication techniques generally employed with unsurfaced polycarbonate sheet products. This product is designed to accommodate heat bending, however, care must be taken to avoid applying too much heat to prevent damage to the C-350 surface. When solvent welding, it is recommended that the C-350 surface be removed to achieve the best bond strengths. For more information refer to SciCron Technologies Technical Information Bulletin No. SP-02.
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.
  • Surface resistivity of 106 - 108 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.
  • Superior impact resistance
    Provides exceptional shatter resistance for safety.
  • Superior flame spread properties
    Provides additional protection for equipment in a fire.
  • Superior fabrication and bending characteristics
    Provides maximum versatility and workability during part fabrication.
  • Superior chemical resistance
    Reduces risk of solvent or chemical surface damage.
  • Excellent clarity
    Premium optical quality polycarbonate with clear C-350 surface minimizes visible distortion.

Precautions:
  1. Polycarbonate plastic is a combustible thermoplastic. Avoid exposure to flame and excessive heat. Observe fire precautions appropriate for comparable forms of wood and paper.
  2. For building applications, comply with applicable code regulations.
  3. Clean with soap and water. Do not use abrasives. Avoid inappropriate contact with solvents.
