PC-300 ™ PolycarbonateStatic Dissipative Plastic Description PC-300™ 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-300™ 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-300 Polycarbonate offers exceptional design versatility since it fabricates simply, is light in weight and is available in large sheet sizes. It also exhibits superior impact resistance and flame spread properties, plus excellent clarity, chemical resistance, and mar resistance.Applications PC-300 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 semi-conductor, electronic, and micro-manufacturing industries. Typical applications include; guards, covers, windows, doors, and access panels for electronic equipment, assembly machines and instruments; conveyor line covers; transparent room partitions; process equipment enclosures; and mini-environment glazing panels. 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-300 Polycarbonate is easily fabricated into flat surface configurations using the same equipment and fabrication techniques generally employed with unsurfaced polycar-bonate sheet products. It should not be used for heat formed bent configurations since the hard, cured C-300 surface is not designed for heat bending. When solvent welding, it is necessary to remove the C-300 surface mechanically to achieve a good bond. For more information on fabrication refer to SciCron Technologies Technical Information Bulletin No. SP-01.Features and Benefits l Cannot be tribocharged when properly groundedPrevents build-up of static charge and accumulation of harmful contamination. l Electrostatic decay in less than 0.05 second per Federal Test Standard 101C, Method 4046.1Results in rapid static dissipation without arcing. l Surface resistivity of 106 - 108 ohms per squareProvides for ESD control without the need for ionization. l Permanence in static dissipation performanceAvoids cost of application of temporary topical anti-stats. l Humidity independent static charge controlAvoids inconvenience of maintaining high levels of humidity and damage caused by such humidity. l Advanced technology, uniform surface treatmentAvoids conductive discontinuities (charged “hot spots”) often found with non-uniform temporary topical anti-stats. l Superior impact resistanceProvides exceptional shatter resistance for safety. l Superior flame spread propertiesProvides additional protection for equipment in a fire. l Hard, mar resistant, durable surfaceC-300 surface, harder than the base plastic, reduces risk of damage to the sheet surfaces. l Superior chemical resistanceReduces risk of solvent or chemical surface damage. l Excellent clarityPremium optical quality polycarbonate with clear C-300 surface minimizes visible distortion. Availability PC-300 Polycarbonate is available in clear and transparent gray and bronze tints. Other colors are available by special order.Standard Dimensions (Nominal) Thickness: 3mm (1/8”), 4.5mm (3/16”), 6mm (1/4”), 9mm (3/8”), 12mm (1/2”) plus films 10-90 mils Standard Sheet Size: 48” x 96” Other sizes and thicknesses available upon request.

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. PC-300-7 2/04
