Engineered for critical cleaning in the optics and semiconductor industries, the PRT-1091 Polyester Cleanroom Wipes offer a heavy-duty 160 g/m² weight for maximum absorbency and durability. These wipes are washed in 17MΩ deionized water to achieve an ultra-clean profile suitable for ISO Class 4 through 9 and GMP Grade A through D facilities. Featuring a four-sided sealed-border created by thermal heat, the PRT-1091 effectively eliminates the risk of edge-fraying and particulate shedding during use. The 0.55mm thick material is structured with high-density filaments to provide superior lifting power for residues and oils without leaving streaks or fibers behind. These 9×9 inch wipes are a reliable choice for technical environments that demand a robust, high-absorbency wiping solution that maintains strict contamination control and protects expensive technical equipment from surface damage.
