The PRT-2091 NV is an ultra-strong, high-density microdenier wipe designed for the most delicate cleaning tasks in semiconductor and optics manufacturing. With a heavy weight of 240 g/m² and a thickness of 0.53mm, these wipes are composed of an 80% polyester and 20% nylon blend that provides an incredibly soft and tactile feel, ensuring scratch-free results on sensitive surfaces. Each wipe is manufactured from 100% continuous-filament yarn and laundered in 17MΩ deionised water to meet the rigorous standards of ISO Class 4–9 and GMP Grade A–D environments. The edges are precision laser-cut to seal fibers and prevent particulate shedding at the borders. These 9×9 inch wipes offer elite-level lifting power for oils and microscopic contaminants, providing the high-end purity and mechanical strength required for critical cleaning in advanced technical laboratories and high-purity production cleanrooms.
