Static Dissipative Plastic
AC-300™ 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-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. AC-300 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, chemical resistance, surface hardness and mar resistance.
Features and Benefits
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.

1. Acrylic 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.
