Series 302, a polyester-cellulose non-woven wipe, is versatile, both in microbiological controlled zones and in purely particle controlled areas. Although it is made of a non-woven fabric, the wipe has a certain abrasion and tear resistance (even when moist).
The wipe material combines the different strengths of cellulose (➜ absorbency) and polyester fibre (➜ abrasion resistance) and is therefore also a happy medium in terms of costs.
The hydro-bonded non-woven fabric is, in direct comparison to the series 300 and 303, cleaner.
Series 302 is also available in a validated sterile version.
Facts
Polyester-cellulose
Non-woven, 45% PES / 55% CEL, hydroentangled
Properties
- 45% polyester / 55% cellulose
- hydro-entangled non-woven fabric
- low particle and fibre emission
- relatively abrasion resistant
- good absorptive capacity
- double bag packing
Advantages
- good chemical compatibility with different solvents and cleaning agents
- one of the purest polyester-cellulose non-woven wipes
- multipurpose
- available validated sterile
Applications
- all-purpose wipe partly also for more sensitive areas
- absorbency of liquids and spills
- also for the cleaning of (particulate) more critical areas (when pure polyester wipes cannot be used)
- workplace cleaning – especially for smooth 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.
