Resistance to extremes of temperatures Chemical Resistance Flame Retardancy and Electrical Properties Low Friction, Non-stick and Weather Resistance Comparison between fluoropolymers and other plastics

Chemical Resistance Fluoropolymers remain stable in most chemical environments and are highly resistant to chemicals. Fluoropolymers do not dissolve in solvents. Fluon® PTFE and Fluon® PFA offer the most outstanding chemical resistance of all plastics. As a guideline the table below shows the chemical resistance of Fluon® PFA.
