Rev. B (9/18) Page 1 of 3 770-424-4888 • www.chemtronics.com Sealed Polyester Swabs Product# 34860, 38040, 38140, 38540, 36060, 36061I, 36850 Product Description Coventry™ Sealed Fabric Swabs are constructed from either a non-woven or a knit fabric. The head is thermoformed and welded to the handle in a single step using a proprietary process that yields an exceptionally clean swab that will not fall apart. The heads are made from either polyester knit, a polyester/nylon microfiber knit, or a polyester non-woven fabric. These swabs are acid and solvent resistant, including acetone.

  • Excellent strength
  • High absorbency and absorbency rate
  • Excellent solvent compatibility
  • Does not generate loose fibers or particles
  • No adhesives or binders are used in the construction
  • Good for tight tolerance work
  • Micro-fiber has increased number of microspace to trap more particles, regardless of wet or dry
  • Available Aqua-Prime™ processed Typical Applications Coventry™ Sealed Polyester Swabs can be used to:
  • Validate biogenetic/pharmaceutical surfaces
  • Clean disk drive components
  • Clean sensitive surfaces in optics
  • Clean aerospace hardware Compatibility Fabric Heads and Polypropylene Handles are compatible with most common solvents and dilute or weak acids, as well as ketones such as acetone or methyl ethyl ketone. Aqua Prime™ process available on all polyester swabs.
