PTFE
Steel columns lined with POLYFLURON PTFE can be used for distilling, rectifying (evaporating, condensing), absorbing, quenching, washing or desorbing liquids or liquid mixtures. These liquids can be extremely corrosive media such as hydrofluoric acid (HF), hydrochloric acid (HCl), sulfuric acid (H2SO4), phosphoric acid (H3PO4) as well as their intermediate products and derivatives, which result directly or indirectly during their production or processing.
