Foamtec’s UltraSORB: The Ultimate Solution for Lint-Free and Highly Absorbent Cleanroom Cleaning

by | Sep 22, 2023


Cleanrooms are critical environments where precision and cleanliness are of utmost importance. However, cleanroom operators often face a dilemma when selecting cleaning materials that provide liquid absorbency and lint-free performance. Traditional fabric wipers rely on absorbency from high surface area but tend to shed particles, making them unsuitable for these demanding applications. Enter Foamtec’s UltraSORB absorbent sponge wiper – a game-changer in cleanroom cleaning.

The Absorbency vs. Cleanliness Dilemma

Cleanroom operators have long grappled with balancing absorbency and cleanliness in their cleaning materials. Traditional fabric wipers have relied on high surface area to provide excellent liquid absorbency. Still, they often incorporate cellulose into their fabric, compromising their particle-shedding performance. This can be problematic in cleanroom environments where lint and particles must be meticulously avoided.
