PC-300 Polycarbonate for Cleanroom Construction
StatiCon® Glazing is a family of transparent plastic sheet products designed to control static electricity in cleanroom construction applications. PC-300 Polycarbonate, a member of this family, 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 the cleanroom builder exceptional design versatility since it fabricates simply with field tools, has 250 times greater impact resistance than tempered glass, is less than half the weight of glass for the same thickness sheet, and is available in large sheet sizes. It also exhibits superior flame spread properties, plus excellent clarity, and chemical resistance.
|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 – 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 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. Inherently light weight material with large sheet sizes – Allows much greater design and installation flexibility than heavy, fragile, conventional glazing. Hard, mar resistant, durable surface– C-300 surface, harder than the base plastic, reduces risk of damage to the sheet surfaces. Superior chemical resistance – Reduces risk of solvent or chemical surface damage. Excellent clarity – Premium optical quality polycarbonate with clear C-300 surface minimizes visible distortion.

|Light Transmission Spectral Analysis|
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.
