AC-350Acrylic (Bending Grade) Static Dissipative Plastic

Description AC-350 Acrylic is a plastic sheet product designed to control static electricity for a wide range of end uses. It is a premium quality acrylic 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. AC-350 Acrylic offers exceptional design  versatility since it fabricates simply, is light in weight and is available in  large sheet sizes. It also exhibits excellent optical properties and chemical resistance, and superior bending properties. Applications AC-350 Acrylic 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  forming or bending, such as; covers, windows, doors, and access panels for  electronic equipment, machines and instruments; fabricated desiccators, cabinets, and boxes with heat bent parts; and formed process 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 AC-350 Acrylic is easily fabricated into a variety of flat and bent configurations using the same equipment and fabrication techniques generally employed with unsurfaced acrylic 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.

Features and Benefits Cannot be tribocharged when properly grounded - Prevents buildup 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. Excellent optical properties - C-350 surface provides excellent  clarity for optimum use of available light. Superior chemical resistance - Reduces risk of solvent or chemical  surface damage. Superior fabrication and bending characteristics - Provides maximum  versatility and workability during part fabrication. Availability AC-350 Acrylic, in cell cast type, is  available in clear and a variety of standard transparent colors including tints  which filter wave-lengths that can interfere with processing operations. White  translucent and colored opaque grades are also available. Continuously cast and extruded types are available in some sizes and thicknesses upon request. Note: Cell cast is a premium form of acrylic plastic but it has a wider thickness variation than other acrylic types. Therefore, continuously cast or  extruded material should be specified if a narrow thickness tolerance range is required.
