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. We provide the services to conduct refining studies, construct variable basis weight, variable density handsheets, and analyze the resulting materials for a wide range of properties.
