Product Description
Chemtronics 6259BESD Poly Double-Onyx™ ESD Wipes are made from 2nd generation black no-run monofilament polyester knit, providing excellent strength, absorbency, and chemical compatibility. These wipes are ideal for general cleanroom and equipment maintenance, or any critical applications where lint is intolerable. Their black color is particularly valuable for inspecting light-colored soils and dust. Conductive carbon filaments are knitted into both sides of the wipes, with double the density compared to other ESD wipes, ensuring maximum continuity to ground within the 10⁷-10⁹ ohm range.
Key Features of Chemtronics 6259BESD Poly Double-Onyx™ ESD Wipes
- Class 100–1000 (ISO 5-6) black, laser-sealed edge polyester wipe
- Static dissipative within 10⁷-10⁹ ohm range, compliant with S20.20
- Double-sided, double-density conductive material for optimal ground continuity
- High durability for cleaning rough, abrasive, or irregular surfaces
- Monofilament “no-run” construction, preventing loose fiber release
- Excellent solvent and acid resistance
- Low ionic, nonvolatile residue, and particle contamination
- Good absorbency
