Serie 302 S

Polyester-cellulose wipe

Back to our sterile dry wipes

The validated sterile version of the Series 302, a polyester cellulose non-woven wipe, is versatile, both in microbiological controlled zones and in purely particulate controlled areas. Although made of a non-woven fabric, the wipe is characterized by a certain abrasion and tear resistance (even when moist).
The material of the wipe 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.

Polyester-cellulose

Series 302 S

Non-woven, 45% PES / 55% CEL, hydroentangled, validated sterile

-
-

Properties

  • 45% polyester / 55% cellulose
  • hydro-entangled non-woven fabric
  • validated sterile
  • 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

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


123456789low dust


ABCDE

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.
