Cation Membrane T39

Cat.No    ACM-IM-125
  • Description
  • Application

A PK reinforced cation exchange membrane (CEM). The polymer backbone of this membrane is based on a proprietary hydrocarbon resin. The mechanical reinforcement is composed of poly ether ether ketone (also known as PEEK or PK) and it has the open mesh style.

Diffusion dialysis for caustic solutions.
