What they make

All Other Plastics Product Manufacturing326199

Avanpore develops nanoporous PEEK hollow-fiber membranes for molecular-level separations in aggressive solvent and chemical environments. The company uses a proprietary manufacturing method to convert PEEK, an engineering polymer, into nanoporous hollow fibers designed for use in harsh liquid streams where conventional membrane materials fail. The membranes are engineered for chemical resistance in solvent, acidic, basic, and hydrocarbon environments, along with thermal stability and high selectivity for precise molecular separations.
