Contec® Polynit Sterile

The Polynit Heatseal heavy weight wipe is constructed from 100% textured polyester knit that is extremely low in particles and fibers, has good sorbency with solvents and is abrasion and chemical resistant. The wipe is laser-cut, which bonds the fibers at the edges of the wipe. This creates a very clean, nonabrasive edge which allows 100% utilization of the wipe surface. Validated sterile per AAMI Guidelines to a 10-6 SAL.
