PNB™-R85 Reinforced Anion Conductive Membranes
SKU: ME0453
PNB™-R85 Reinforced Anion Conductive Membranes
PNB™-R85 Membranes are mechanically reinforced anion exchange membranes (AEMs) made from PFAS-free polynorbornene ion-conductive polymer. Built on high glass transition temperature poly(norbornene) copolymers, they offer exceptional thermal and chemical stability.
With a hydroxide conductivity over 200 mS/cm at 80°C, they retain 99% conductivity in KOH at 80°C for 1,200+ hours, ensuring high durability in alkaline environments. Their reinforced structure enhances toughness, making them easy to handle and ideal for pressurized systems. Featuring functionalized norbornene chemistry, PNB™-R85 delivers high anion conductivity, stability, and optimized ion exchange capacity for demanding applications.
