The Polynit Wipe is made from filament polyester and is knitted in a special stitch which reduces degradation of the wipe and subsequent particle generation. The Polynit Wipe is specifically designed for ISO Class 5 or cleaner environments and is exceptionally low in particles and extractable residue and has good sorptive capacity. It is abrasion and chemical resistant making it ideal for wiping down exterior surfaces of products and interior surfaces of equipment.
