UHMW Polyethylene 35 Micron Porous Sheet / Hydrophilic / 18" x 18" (457mm x 457mm) Sheet / 1/4" (6.4mm) Thick / (1 Sheet)

Polypropylene and Ultra High Molecular Weight (UHMW) Polyethylene Porous Sheets are manufactured in the United States with free-sintered materials that produce filter media that provides excellent filtration of ultra fine particles and outstanding flowability of gases and liquids. They are produced of high purity resins approved by the FDA and USDA. The filtration varies depending on the micron size material selected. They can be used for filtering particulate, diffusing or venting gases or wicking applications. We offer two varieties that achieve 99.8% filtration efficiency. Hydrophilic sheets have a strong affinity to liquids and allow wicking of aqueous solutions. Hydrophobic sheets are specially formulated to repel liquids. These sheets have excellent corrosion resistance and are chemically resistant to most acids, alkali, solvents and hydrocarbon based fuels. Our sheets can be gamma or ethylene oxide sterilized. UHMW Polyethylene can operate safely at 180°F, or 210°F for a short period of time.
