UNCOMPROMISING CHEMISTRY DESIGN FOR DIAPHRAGM PUMPS Fluoropolymers and perfluoro elastomers are materials containing fluorine atoms in their chemical structures. Due to their outstanding chemical resistance and their extremely low surface energy - for low material adhesion -VACUUBRAND uses these materials for all media-contacted parts in their chemical diaphragm vacuum pumps. One of the most distinguishing properties of PTFE is its outstanding chemical resistance, except for some extreme conditions such as molten alkali metals or elemental fluorine. Basically PTFE is not soluble in any...
