Felted Cleanroom Foam Wiper

FirmWIPE® Wipers: The Best Solution for Cleaning Medical Devices and Tooling

If you are looking for a high-performance cleanroom wiper that can effectively remove excess silicone, adhesives, inks, and other contaminants from medical devices and tooling, look no further than FirmWIPE®. FirmWIPE® is a felted cleanroom foam wiper that is specially designed for cleaning applications in ISO 7 and ISO 13485 cleanrooms. FirmWIPE® has the following features and benefits:

  • High-strength and durability: FirmWIPE® is made of fully cross-linked, felted polyurethane foam that has high tensile and abrasion resistance. It will not snag or rip on sharp edges, ensuring contamination-free cleaning of equipment such as injection molding tooling, 3D printing nozzles, and screen printing squeegees.
  • High absorbency and holding capacity: FirmWIPE® has high absorbency, fast wicking, and drip-free holding of solvents, mold release, and liquid silicone rubber. It can effectively clean and apply these materials on medical devices and tooling, reducing waste and improving efficiency.
  • Low impurity and biocompatibility: FirmWIPE® is free of impurities such as Sulphur, so it will not inhibit the curing of medical-grade platinum silicone. It is also processed and laundered to ISO 5 cleanliness specifications and to pass ISO 10993 cytotoxicity and pyrogen specifications, ensuring biocompatibility and safety for medical applications.
  • Cost-effectiveness and sustainability: FirmWIPE’s felted construction and ultra-fine porosity enable repeated cleaning of tooling and surfaces with excess adhesive or silicone, allowing the reduction of wiper consumption and operator time. FirmWIPE® is also recyclable and biodegradable, minimizing environmental impact.

FirmWIPE® is the best solution for cleaning medical devices and tooling that are highly susceptible to foreign material (FM) contamination. FirmWIPE® is widely deployed in medical device cleanrooms for cleaning tasks such as:

  • Removing excess liquid silicone rubber from injection molding tooling and devices
  • Cleaning epoxy dispensers and applicators
  • Wiping off excess adhesives from medical device assembly
  • Cleaning 3D printing nozzles and build plates
  • Removing inks from screen printing squeegees and substrates
