Tohoku University Technology: Non-fluorinated PTFE water dispersant: T19-448
Able to use PTFE particles without fluorinated dispersant
PTFE (Polytetrafluoroethylene) particles are industrially important particles used for many purposes. They are often used with their surfaces coated with dispersants and dispersed in water. Fluorinated dispersants are used as dispersant, but there is a strong concern about its bioaccumulation and environmental persistence, and it is necessary to find an alternative agent that doesn’t use fluorine. This invention is about a non-fluorinated dispersant that can disperse PTFE in water.
