Latest Patents

Malarkey's latest patents focus on a process for producing microporous or open ultrafiltration poly (tetrafluoroethylene-co-perfluoro-(alkyl vinyl ether)) (PFA) and poly (tetrafluoroethylene-co-hexafluoropropylene) (FEP) film membranes. These membranes are created from a melt blend of 10 to 35 weight percent of PFA or FEP and a chlorotrifluoroethylene oligomer solvent. The innovative process involves shaping the melt blend and coating one or more surfaces with the solvent before phase separation occurs. This technique results in membranes with larger pores on the coated surface compared to those that are not coated. The process also includes cooling the shaped melt blend to effect phase separation and crystallization, followed by solvent extraction and heat setting to prevent shrinkage.
