Q-S Technologies, Inc. specializes in fluoropolymer insulation systems. They resist attacks from most chemicals and solvents, which rapidly deteriorate other materials. Fluoropolymers are essentially inert! Fluoropolymers provide customers with improved retention of properties after aging in elevated temperatures over other materials. Uniquely suitable and stable for most heating applications.
