Why is Viton (FPM) resistant to Phosgene?
Viton (FPM) shows excellent resistance to Phosgene 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.
