PC 350 PolyCarbonate

PC-350 Polycarbonate (Bending Grade)
Static Dissipative Plastic

PC-350 Polycarbonate is a plastic sheet product designed to control  static electricity for a wide range of end uses. It is a premium quality  polycarbonate sheet which has been surfaced with SciCron Technologies  proprietary, clear, C-350 static dissipative surfacing. 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.

PC-350 Polycarbonate resists  tribocharging under all circumstances and cannot generate a charge when properly  grounded. This makes it ideal for use in manufacturing 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 semiconductor, electronic, and micro-manufacturing 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, 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.

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 not necessary to  remove the C-350 surface to achieve a good bond if the welding adhesive contains  some dissolved plastic. For more information on fabrication 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. 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.
