PC-350™ Polycarbonate is a plastic sheet product that controls static electricity for many applications, including bent and contoured equipment covers, guards, enclosures, and panels. It is a premium quality polycarbonate sheet with a coating that prevents charge generation on the sheet surfaces. This controls particulate attraction and prevents electrostatic discharge (ESD) events completely independent of humidity. PC-350™ Polycarbonate fabricates simply, is light in weight and is available in large sheet sizes. It has excellent clarity and chemical resistance, plus superior impact resistance, flame-spread properties, and bending characteristics.

PC-350™ Polycarbonate is easily fabricated into a variety of flat and bent configurations using the same equipment and fabrication techniques generally employed with un-surfaced 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 PC-350 surface. When solvent welding, it is recommended that the PC-350 surface be removed to achieve the best bond strengths.

For general purpose grade see PC-300.

  • 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.
  • PC-350™ Polycarbonate is not designed for exposure
    to direct sunlight and is not warranted for external applications.
