Absorbent, nonabrasive optical-grade Abaca cellulose wipes. Nonwoven, long staple cellulosic fibers are wet laid in a paper making process to form an extremely clean sheet utilized in the C5 and C6 wipers. These wipes have very low extractable levels, moderate particle generation, and are best suited for non-abrasive applications due to their low strength. Ideal for drying critical products. Used for cleaning delicate optical instruments, products and devices. The principle difference between C5 and C6 is the higher basis weight of the C6.
