TX704 FoamWipe 6" x 9" x 1/8" Polyurethane Foam Cleanroom Wiper

TX704 FoamWipe is a low-linting (no wiper is truly ‘zero-lint’ in every process condition), low particle-generation polyurethane foam cleanroom wiper designed for spill control, cleaning, and solution application in controlled environments. It is made from open-cell, 100 pore-per-inch (PPI) polyurethane foam and is precision cut with a cut edge to help reduce particle generation while providing a soft, non-abrasive wiping surface that also works well as a padded work surface during assembly or maintenance tasks.

• Size: 6" x 9" x 1/8" (15 cm x 23 cm x ~0.32 cm) nominal
• Material/Structure: Open-cell polyurethane foam, 100 PPI (fully reticulated foam construction)

• Silicone: Silicone free
• Packaging: 60 wipers/bag (double bagged); 8 bags/case
• Wiper family: FoamWipe
• ISO environment: ISO 6 – 8 (Class 1,000 – 100,000); EU Grade B – D
• Temperature note: Appropriate for use with temperatures less than 350°F (177°C)
• Shelf life: Non-sterile (dry) – 5 years from date of manufacture
• Absorbency (typical): Sorptive capacity 900 mL/m²; sorptive rate 3.9 seconds (IPA)
• Contamination data (typical): IPA extractant NVR 1.10 g/m²; DIW extractant NVR 0.30 g/m²
• Ionics (typical): Na 1 ppm; K 0.009 ppm; Cl 10 ppm
• Use environments: Cleanroom maintenance/assembly, wipe-downs, and solution application where a padded, non-abrasive foam surface is advantageous (final suitability depends on your process and cleaning method)

Texwipe (an ITW company) positions FoamWipe as an engineered foam wiping platform for controlled environments, built around consistent foam structure (100 PPI open-cell polyurethane), cleanroom manufacturing, and performance baselines (absorbency, NVR, particles/fibers, and ionics) intended to support qualification and repeatability. The line is described as silicone free and packaged to support cleanroom handling, with lot coding called out as a traceability and quality-control aid.

SOSCleanroom (SOS) supports that manufacturing discipline with a close working relationship with Texwipe focused on continuity of supply, clean documentation handoff (certs, lot traceability), and practical application support—so customers can standardize foam wiping materials with predictable performance while maintaining procurement reliability and audit readiness.

• Constructed from 100 PPI polyurethane foam for high absorbency and solvent hold
• Precision cut for low particle generation; cut edge
• Silicone free; double-bagged for cleanroom use
• Unique texture positioned for picking up fine powder
• Good chemical resistance for compatibility with a variety of solutions
• Autoclave safe
• Individually lot coded for ease of traceability and quality control

• Low particle generation: Precision-cut foam is designed to reduce particle contribution during wipe-downs (process-dependent)
• Excellent solvent capacity and hold: Reticulated foam structure supports controlled wetting and solution transfer to surfaces
• Non-abrasive wiping: Soft foam surface supports delicate-contact wipe-downs and reduces scratch risk vs. rougher substrates
• Dual-purpose handling: Can serve as a padded work surface to protect parts and finishes during staging and assembly
• Program readiness: Lot coding and published technical baselines support standardization and documentation expectations

• For use in cleanroom maintenance and assembly operations
• Wiping and cleaning surfaces, equipment and parts
• Applying and removing lubricants, adhesives, residues and other solutions including disinfectants
• Cleaning with solvents such as isopropyl alcohol (IPA), ethanol, acetone, and degreasers
• Padded work surface
• Ideal for applying cleaning solutions to large surfaces
• Lining trays for holding, protecting, drying and storing of parts, equipment and devices

• Use straight-line strokes: Wipe top-to-bottom or left-to-right with light, even pressure to reduce re-deposition and avoid “scrubbing” particles into surfaces.
• Control wetting: Dampen—do not over-saturate—so you maintain control and reduce dripping on vertical panels or large fixtures.
• Rotate contact surfaces: Use a fresh area of the foam face as it loads; change wipers early when removing residues or powders to avoid smear-back.
• Powder pickup technique: Use a gentle “press and lift” motion when practical rather than dragging a loaded face across the surface.
• Padded work surface discipline: If using TX704 as a padded surface, replace it when it becomes visibly soiled or solvent-wet to avoid transferring residues back to parts.
• Autoclave note: If autoclaving dry wipes for a specific workflow, follow site validation and packaging/handling SOPs.

• Foam vs. knit polyester (TX1009B): Choose TX704 when solvent hold, padded handling, and non-abrasive foam contact are priorities; choose knit polyester when scrub strength and broader general wipe-down coverage per wipe are the priority.
• Foam vs. sealed-edge polyester (TX2069 / TX8949): Choose sealed-edge polyester when abrasion-heavy wiping on sharp edges drives snag risk; choose foam when cushioning and solution application behavior are more important than abrasion resistance.
• Foam vs. cellulose/polyester blends (TX609): Choose blends when you want a more paper-like “pick-up” feel and higher general absorbency; choose foam when you want controlled solvent release and a padded work surface.
