The 429-IO series, a microfibre woven wipe made of polyester and polyamide (70/30), is characterised by very good cleaning performance, even with greasy soiling. Even though it is made only from synthetic fibres, the wipe has sufficient absorption capacity for aqueous solutions. It is chemically resistant to acids (peracetic acid), alkalis (caustic soda, nitric acid), bleaching agents and solvents (isopropanol, acetone, benzene compounds). The wipes are primarily used in clean particulate-controlled areas, but can also be used at any time in microbiologically controlled zones. Cutting is carried out using ultrasound, which seals the edges. After cutting, the wipes are professionally decontaminated in a cleanroom laundry and packaged under ISO class 5 conditions. The wipes have relatively low levels of ionic and metallic contamination thanks to the cleanroom-compatible post-cleaning process.
Facts
Special requirements
Microfibre wipe, woven, 70% PES / 30% PA
Properties
- 70% polyester / 30% polyamide
- woven from microfibre filaments
- ultrasonically cut and sealed edges
- decontaminated in a cleanroom laundry
- vacuum-packed twice in PE film in a cleanroom
Advantages
- very good cleaning performance due to the elastic and dense weave and the structured surface
- low abrasion even under heavy mechanical load
- high chemical resistance and low abrasion due to the twisted threads
Applications
- effective removal of particulate and organic contamination
- very well suited for wiping highly sensitive surfaces
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.
