Why is Viton (FPM) resistant to Hydrofluoric Acid?
Viton (FPM) shows excellent resistance to Hydrofluoric Acid due to its fluorinated rubber structure providing exceptional resistance to oils, fuels, and many chemicals.
⚠️ When NOT to use Viton (FPM)
Avoid using Viton Fluoroelastomer with ketones, esters, amines, and hot water/steam. Excellent for fuel and oil applications.
