Expanded Materials For Superior Filter Designs
Filtration and separation are key criteria for industries that produce semiconductors, process chemicals, and pharmaceuticals, or systems that control gas or liquids. Dexmet custom manufactures MicroGrid® and PFOA-free PolyGrid® materials in a multitude of open area configurations with controlled pore sizes to provide more consistent particle removal, flow rates, and pressure drops for your filtration application.
Expanded MicroGrid® can be used for either primary filtration applications to protect critical downstream components or as internal cores to support the filtration media. Typically, expanded metals are used for these applications because they require strength and operate at higher pressures.
Expanded PolyGrid® materials are used primarily as membrane support materials on the upstream and downstream of the membrane. Expanded polymers can be used as a primary filter but typically for lower pressure air or gas applications.
Dexmet produces PFOA-Free PolyGrid® expanded Fluoropolymers. PFOA (Perfluorooctanoic Acid), widely used as a polymerization surfactant in making fluoropolymers including PTFE, PFA, and FEP, has fallen under scrutiny by the EPA and FDA for its potential toxicity and widespread presence in the environment and human population. Utilizing Dexmet's fluoropolymers will ensure that your application meets any new EPA or FDA requirements while being safe to the environment.
