The series 416-REC, a 100% polyester wipe knitted from fi laments made from 100% recycled materials, belongs to the new generation of sustainable cleanroom cleaning wipes for more critical areas, both in microbiological controlled and in only particle-controlled zones. After the edges are cut by laser, the wipes are professionally decontaminated in a cleanroom laundry and packaged under class ISO 4 conditions (EN ISO 14644-1). Even though they are made of 100% polyester, the wipes have a decent absorption capacity.
The robust polyester knitted fabric shows its strength on rougher surfaces or with sharp-edged objects and/or surfaces. The wipes have relatively low levels of ionic and metallic contaminants. In addition, there is a low load of non-volatile residues (NVR) and good chemical resistance.
Facts
Polyester
Knit, 100% PES made from 100% recycled materials, 134 g/m², laser sealed edges
Properties
- 100% polyester made from 100% recycled materials
- knitted fabric made of filaments
- edges cut and sealed by laser
- relative low particle and fibre emission
- abrasion resistant
- decontaminated in a cleanroom laundry
- double bag packed in a cleanroom (air cleanliness class ISO 4)
Advantages
- robust wipe
- reduced particle and fibre emission due to the sealed edges
- very wide range of applications
- low ionic and metallic
- available in a gamma-irradiated version
Applications
- cleaning wipe for critical and non-critical areas
- well suited for angular, rough surfaces and objects that might prematurely damage a non-woven fabric wipe
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.
