Wiper is made from thermally bonded polypropylene and cellulose

Cellulose contributes to wiper's high sorption while the polypropylene provides resistance to strong acids. The soft, pillowy texture makes it ideal for wiping abrasion-sensitive surfaces. The surface texture allows for greater sorption of liquids — wiper can absorb five times its weight in water. Suitable for use in ISO Class 6 (FED-STD-209E Class 1000/M4.5) environments. Packed in an ISO Class 5 (FED-STD-209E Class 100/M3.5) cleanroom.
