GE Energy Debuts Aspire Hydrophilic EPTFE Membrane

GE Energy, Raytown, Mo., reports its new Aspire hydrophilic expanded polytetrafluoroethylene (ePTFE) membrane eliminates the need for filter manufacturers to pre-wet cartridge filters with alcohol before shipping, reducing process time and costs and helping to prevent bacteria growth during storage because the filters are shipped and stored dry. According to the company, the membrane offers bacteria retention, high flow rate and chemical resistance performance similar to that of hydrophobic ePTFE membranes, as well as durable hydrophilic characteristics and very low extractables.

"This innovation can reduce up to 40 percent of a customer's cost per cartridge," said Chris Keller, senior product manager, GE Energy Services. "There's no longer a need to pre-wet the membrane to flow water across it. End users will receive a membrane that can hold up during liquid microfiltration even after exposure to steam autoclave cycles, certain corrosive chemicals and other severe conditions. The new membrane also helps reduce the environmental impact of the alcohol waste stream."
