Static Dissipative Plastic
Description
CPVC-300™ – FM 4910 is a plastic sheet product designed to control static electricity for a wide range of end uses. It is a Factory Mutual 4910* compliant polyvinyl chloride sheet which has been coated with SciCron Technologies proprietary, clear, C-300™ static dissipative coating. This unique coating 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. CPVC-300 – FM 4910 exhibits excellent flammability and smoke generation properties, plus superior chemical resistance, surface hardness, and mar resistance.
*The CPVC substrate used to make this product has been tested according to procedures outlined in the Factory Mutual Clean Room Materials Flammability Test Protocol (Class 4910) and is listed as an approved material in the Factory Mutual Research Approval Guide. It has been formulated to resist fire and to emit low levels of smoke when tested according to this protocol. The substrate coated with SciCron Technologies non-flammable C-300 coating has not been similarly tested.
Applications
CPVC-300 – FM 4910 resists tribocharging under all circum-stances and cannot generate a charge when properly grounded. This makes it ideal for use in manufacturing and assembly operations for charge sensitive electronic com-ponents 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 clean rooms in the semi-conductor, electronic, and micro-manufacturing industries. Applications include: perimeter windows, partitions, laminar flow air containment screens, mini-environment glazing panels, and pass-thru modules; enclosures, covers, and doors for equipment, machines and instruments; and fabricated desiccator cabinets and boxes.
Fabrication
CPVC-300 – FM 4910 is easily fabricated into flat surface configurations using the same equipment and fabrication techniques generally employed with unsurfaced CPVC sheet products. It should not be used for heat formed bent configurations since the hard 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
- 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 without the need for ionization. - 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. - Factory Mutual Class 4910 compliant Substrate.
Substrate meets clean room performance requirements called out in FM 4910 guidelines. - Excellent flame spread properties
Provides additional protection for equipment in a fire. - Excellent smoke generation properties
Improves visibility and reduces area contamination in a fire. - 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.

Precautions:
- CPVC-300™ – FM 4910 is designed to resists ignition, however, CPVC plastic is a combustible thermoplastic which emits toxic and corrosive gases upon combustion. Avoid exposure to flame and excessive heat.
- For building applications, comply with applicable code regulations.
- Clean with soap and water. Do not use abrasives. Avoid inappropriate contact with solvents.
