Sigracet 39 BC is a non-woven carbon paper with a Microporous Layer (MPL) that has been PTFE treated to 5%. It has a total thickness of 325 um (microns). SGL 39 BC is a great low-cost alternative to conventional woven carbon cloth Gas Diffusion Layer (GDL) materials.
Sigracet 35 BC will be discontinued in due time (possibly January 2016) and permanently replaced by Sigracet 39 BC.
