These continuous-filament 100% knitted polyester wipers are designed for critical cleanroom applications.
- Critically low particles, fibers, ions, and extractables
- High absorbency
- Pinsonic design adds surface texture to aid in stubborn residue removal
- Abrasion- and chemical-resistant, double-ply thickness
- Patented sealed edge process combined with tubular design offers excellent abrasion resistance for the toughest cleaning applications
Tubular construction yields only two open edges, which are heat-sealed to prevent contamination. No adhesives, which could extract and contaminate, are used in the heat-sealing process. Recommended for use in ISO Class 3 (FED-STD-209E Class 1/M1.5) environments.
Wipers are laundered and packaged in an ISO Class 4 (FED-STD-209E Class 10/M2.5) cleanroom and double-wrapped to ensure cleanliness. Wipers are stacked.
