Static Dissipative Performance

The surface resistance spectrum in the top chart below shows materials in the range (10⁵ to 10⁹ Ohm) provide ideal dissipative performance. Static charge densities are limited by conductors and dissipative materials (lower chart below) while insulative materials are prone to causing ESD damage.

The potential for damage from electrostatic discharges depends on charge density and how charges are handled by the surfaces they reside on. Spots of charge (high charge densities) persist on insulative surfaces for long periods of time with little or no charge dissipation. Damaging static discharges can occur from insulative surfaces.

Conductive surfaces dissipate electrostatic charges rapidly which can cause electrical shorts and expose electrical components and devices to higher than expected voltages. Dissipative surfaces do not allow charge densities to build-up and safely dissipate them over their full surface area greatly reducing the risk of discharge and potential damage.

• SCK: Polycoated Kraft
• MOQ: 9" x 1640' for single-coated tapes and 9" x 1000’ for double-coated tapes.

• All tapes are REACH and RoHS compliant

  All products are designed to be die cut with appropriate tooling.

• Special care should be taken to avoid skin oils or finger prints on the static dissipative side of the tape as they may interfere with measuring surface resistance.
• Measurements of surface resistance are done in compliance with standard ANSI/ESD STM.11.11 for accurate and repeatable results.
• The static dissipative properties remain intact during short exposures to temperatures up to 260 C, but can be reduced by exposure to temperature greater than 260 C. Testing of your application is recommended to confirm actual performance.
• The static dissipative properties can be reduced by exposure to strong acids and bases. Testing in your application is recommended to confirm performance.
• The surface on which the tape is to be applied should be clean, dry and free of any surface contamination, such as dust, oil or rust. Isopropyl alcohol would be a recommend solvent to clean the surface.
• Flame retardant tapes are not recognized by UL, but have been tested to the UL94 standard by Polyonics.
• See Polyonics document fr_ss_11 for additional information on fire retardant feature.
