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.

Best-seller note: TX704 is frequently chosen when teams want a foam wipe that holds solvent well, supports controlled solution application on larger surfaces, and can double as a non-abrasive padded work surface in ISO 6–8 environments.

About the Manufacturer:

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.

TX704 Benefits:

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

Common Applications:

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

Best-Practice Use:

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.

Selection Notes (TX704 vs. Other Options)

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.

ISO 14644 Operations Control FoamWipe™ Polyurethane Foam High Absorbency / Cushion 6" x 9" x 1/8" Lot Traceability

Texwipe TX704 FoamWipe™ 6" x 9" x 1/8": cushioned foam wiping for sensitive surfaces, grooves, and controlled liquid handling

Texwipe TX704 FoamWipe™ is a polyurethane foam cleanroom wiper in a 6" x 9" x 1/8" format, commonly selected when operators need cushion, conformability, and higher liquid handling than a thin fabric wipe can provide. Foam wipes are frequently used for cleaning tasks involving grooves, edges, contours, and delicate surfaces, where consistent contact matters and excessive abrasion risk must be avoided. In ISO-controlled programs, foam wipes are especially useful when the method calls for controlled solution application, pickup, and a softer wiping interface.

Operations takeaway: Foam wipes can be excellent “process tools” when the surface geometry is complex. The control requirements are the same: define wetness, define wipe pattern, and define discard triggers so the foam doesn’t become a reservoir for redeposit.

ISO-first context: foam wiping supports repeatable contact on complex surfaces

ISO 14644-5:2025 emphasizes an Operations Control Programme (OCP) governing cleaning methods and materials. A common failure mechanism in cleaning is incomplete contact on seams, machined features, ports, and grooves. Foam wipes help address this by providing a compressible interface that conforms to surface features, supporting more uniform solvent/contact conditions. The benefit is only realized when the method controls solvent loading, wipe direction, and change-out so the foam does not smear or carry contamination across zones.

Control point: Foam holds liquid well. That can improve cleaning or create pooling/streaking if the wipe is over-wet or reused beyond its change-out point.

Specifications (SKU controls for RFQs, SOPs, and receiving)

Product: Texwipe FoamWipe™ TX704
Size: 6" x 9" x 1/8" nominal (15 cm x 23 cm x ~3.2 mm)
Material / structure: Polyurethane foam (verify grade/specs per current manufacturer documentation)
Edge: Foam cut edge; verify finishing/treatment per current manufacturer documentation
Processing: Cleanroom processed and packaged; lot traceability
Typical ISO positioning: Method-dependent; commonly used where conformability and absorbency are needed (confirm for your environment)
Packaging: Verify current bag/case counts and configuration per current manufacturer documentation

Documentation rule: Foam wipe performance can vary by formulation and process. For validated programs, base acceptance on current manufacturer documentation and your method outcomes.

What TX704 is designed to do (typical use cases)

Cleaning grooves, ports, edges, and contoured surfaces where conformability is required
Controlled application and pickup of cleaning solutions where a cushioned wipe interface is preferred
Wipe-downs of sensitive surfaces where excessive abrasion risk must be avoided (validate for your finish)
Pickup/containment of small spills where the foam’s liquid-holding capacity improves control
Maintenance cleaning steps where a thicker wipe supports handling and consistent contact

Method note: For residue-critical surfaces, consider a two-step method: (1) bulk pickup, then (2) a defined finishing pass with the validated wipe required by the SOP.

Best-practice use (control wetness, contact, and discard triggers)

Control introduction: bring wipes into the controlled area per OCP rules (outer packaging removal, staging, storage).
Damp-film control: wet to a controlled damp state; foam can hold excess liquid, so avoid dripping.
Straight-line strokes: use unidirectional, overlapping passes on flat surfaces; avoid circular scrubbing.
Feature work: use controlled pressure and consistent direction into grooves/ports; avoid “sawing” motions that redeposit.
Change-out triggers: replace when loaded, smeary, or when contact quality drops (foam can become a reservoir).
Dispose correctly: discard used wipes immediately into the designated waste stream (do not stage used foam wipes on benches/carts).

Streaking diagnostic tip: If you see haze or pooling marks, reduce wetness, increase overlap control, and shorten the change-out interval. Foam holds solvent longer than many fabric wipes.

Misuse controls & when not to use TX704

If sterility is required: do not substitute a non-sterile wipe for sterile workflows.
If ultra-low residues/ions are gating: verify foam extractables/residue limits against current manufacturer documentation and your internal limits.
If chemistry is aggressive: verify compatibility and safety for solvents/cleaners; do not assume universal compatibility with polyurethane.
If the method requires pre-wetted control: use the protocol-defined pre-wetted wipe format rather than manually wetting foam wipes.

Recommended cleanroom glove pairing (ISO-aligned)

For ISO-controlled wiping applications, pair this cleanroom wipe with a cleanroom-processed, low-particle nitrile glove to reduce contamination transfer during handling, feature work, and solvent wiping.

Ansell Nitrilite® 93-311 Cleanroom Nitrile Gloves — ISO Class 5 (Class 100), cleanroom processed and packaged

Why this matters: Foam wipe tasks often involve higher contact pressure and more handling time. A cleanroom-grade glove reduces transfer contamination and supports consistent technique.

Glove discipline: Change gloves when contaminated, solvent-wet, torn, or after contacting non-controlled surfaces. Treat gloves as part of the wipe system.
