Wet-laid Paper Development

EFT has laboratory facilities and the technical staff to provide applications development, product evaluations and technical support related to wet-laid papers, filtration media, slurry molded shapes and engineered materials, including porous graphite papers for gas diffusion eletrodes. We provide the services to conduct refining studies, construct a wide range of synthetic and natural fiber handsheets varying basis weights, densities and compositions, and analyze the resulting materials for a wide range of properties.
