Description 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.
Applications 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.
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 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.
PC-350 Polycarbonate is available in clear and transparent gray and bronze tints. Other colors are available by special order.
