SW-707-2 Corrosion-Resistant And Soft Sponge Swab

Product Overview

The SW-707-2 is a corrosion-resistant sponge swab with a soft polyurethane foam head formulated for use in chemical-intensive cleaning environments. Unlike standard foam swabs, the head material is constructed from a chemical-resistant foam compound that maintains structural integrity on prolonged contact with strong acids, strong bases, and organic solvents, preventing the foam degradation and surface contamination that unmodified foam materials produce in these conditions.

The swab head measures 24mm in length, 15mm in width, and 9mm in thickness, providing a wide rectangular wiping surface that suits flat substrate cleaning, instrument panel maintenance, and surface preparation tasks where the cleaning agent is a corrosive chemical. The foam softness is maintained even after repeated solvent exposure, allowing the head to conform to slightly uneven surfaces without applying concentrated pressure that could scratch coated or polished substrates.

Chemical Resistance & Handle Construction

The corrosion-resistant foam formulation is compatible with a broad range of chemical cleaning agents including acidic, alkaline, and solvent-based formulations used in laboratory instrument cleaning, electrochemical surface preparation, and semiconductor process equipment maintenance. The foam does not dissolve, swell, or fragment under chemical contact conditions where standard polyurethane foam would fail, ensuring that the swab does not introduce foam particles or chemical byproducts to the cleaned surface.

The polypropylene handle measures 128mm in total length with 6.7mm width and 3.3mm thickness, providing stable grip during chemical cleaning tasks where operator hand protection requires gloved use. The handle material is itself chemically inert and does not absorb the solvents and chemical agents it contacts during operation. Package contains 50 pieces.

Industry Applications & Use Scenarios

The SW-707-2 is applied in laboratory instrument cleaning, semiconductor process equipment maintenance, electroplating line component cleaning, chemical production environments, and precision instrument maintenance where standard foam swabs degrade under cleaning agent exposure. Specific use scenarios include cleaning laboratory glassware contact surfaces, wiping electroplating bath sensor housings, removing chemical residues from reaction vessel internals, and surface preparation in environments where corrosive cleaning formulations are standard process chemicals.
