Kleenguard Polypropylene Fabric—Kleenguard polypropylene is made of five layers of nonwoven fabric, so it is more abrasion resistant and harder to tear than polyethylene/Tyvek fabric. It holds up to occasional contact with nonhazardous liquids, such as water and paint spray. The material is antistatic, so it protects sensitive equipment from electrostatic discharge.
