Properties of Coating systems
E-CTFE (Halar®), ETFE (Teflon®) and PFA (Teflon®) as modified PTFE can be processed by thermoplastic methods as partly or fully fluorinated polymers, and are highly resistant against nearly all organic and inorganic compositions, both in the acidic and alkaline (basic) range. They provide a universal and permanent resistance against acids, alkali, solvents and chlorides. The molecular chain is characterised by a strong carbon-fluorine bond.
E-CTFE exhibits, in addition to high and versatile chemicals resistance also on high temperature levels, an excellent mechanical resistance quality in abrasion resistance, impact resistance and toughness, as well as full vacuum resistance (i.e. good adhesion).
