2019/5/13 · Therefore, one of the leading manufacturers for sealing technology for the numerous AdBlue® tank cap variants of their well-known customers has subjected this high-tech plastic – the expert calls it symmetrically porous, sintered PTFE – to a real acid test.

Comparison of the Performance of Natural Latex Membranes Prepared With Different Procedures and PTFE Membrane in Guided Bone Regeneration (GBR) in Rabbits J Mater Sci Mater Med . 2014 Sep;25(9):2111-20. doi: 10.1007/s10856-014-5241-1.

PTFE nanofibrous membrane may be used for the con-struction of high-performance electret devices. Herein, we report on the application of electrospun PTFE nanofibrous membrane as a high-performance elec-tret NG for self-powered sensors. The design of this

Herein, we present a high-performance membrane-electrode assembly (MEA) with an optimal polytetrafluoroethylene (PTFE) content for HT-PEMFCs. Low or excess PTFE content in the electrode leads to an inefficient electrolyte distribution or severe catalyst agglomeration, respectively, which hinder the formation of triple phase boundaries in the electrodes and result in low performance.

Highlights•Experimental and theoretical study of a high performance PTFE membrane for a VMD application.•The experimental module was carefully designed to capture both hydrodynamic and thermal behaviors.•Membrane mass transfer performances were
