The wipe StatZorb®, made of 98% polyester, 2% conductive fibre, is static dissipative. Its unique grid pattern minimizes "hot spots" and is especially suitable for cleaning work in electrostatically critical areas. The abrasion-resistant wipe is pre-washed in a cleanroom laundry (air cleanliness class ISO 4) and double packed.
Facts
Polyester
Interlock knit, 98% PES / 2% PA/C fibres, antistatic
Properties
- 98% polyester, 2% conductive fibre (polyamide/carbon)
- interlock fabric made from filaments with a specially designed grid weave pattern
- surface resistance 4.3 x 107
- electrostatic discharge < 1.5 sec.
- laser cut and sealed edges
- decontaminated in a cleanroom laundry
- double bag packed in a cleanroom (air cleanliness class ISO 4)
Advantages
- electrostatically conductive wipe on both sides thanks to the grid pattern of the threads with carbon
- reduced particle and fibre emission due to the thermally sealed edges
- abrasion and chemical resistance
Applications
- cleaning work in electrostatically critical areas
- dry wiping of sensitive electronic components
- manufacture of disk drives and magnetic resonance heads
Product recommendation based on cleanroom classes
Of course, cleanroom wipes used in ISO 5 can also be used in ISO 9, but in this case the economic efficiency and usefulness should be considered.
A 1 to 1 allocation of cleanroom wipes to an air cleanliness class according to ISO 14644-1 is not possible. Recommendations can only be made on the basis of special properties relevant from a cleanroom technical point of view, such as "abrasion resistance" or "particle emission". Users can find further information on this in VDI Guideline 2083 Part 9.2.
