ElastaPro makes fluorosilicone materials resist petroleum oils and hydrocarbon fluids. For full specifications and product availability, visit our Fluorosilicone pillar page.
Although fluorosilicones resist many aggressive chemicals, they do not resist all chemicals. Use the fluorosilicone chemical compatibility charts below for information about resistance to:
Fuels
Oils and lubricants
Solvents
Water and coolants
Chemicals and industrial chemicals
Aerospace and specialty chemicals
Food and pharmaceutical chemicals
Each of these fluorosilicone chemical compatibility charts uses this rating system.
Excellent (A): Fully compatible, very low swelling, maintains physical properties
Good (B): Minor swelling or property change; generally acceptable
Fair (C): Significant swelling or degradation; use caution
Poor (D): Not compatible; severe degradation
NR: Not recommended / data insufficient
Important: These are typical values. It is the responsibility of the user to ensure a fluorosilicone’s compatibility with the specific fuel, oil, solvent, or chemical in your application under the expected service conditions.

Notes
Gasoline (unleaded)
A
One of the major strengths of fluorosilicone; excellent resistance.
Aromatic gasoline blends
A–B
Good resistance but swelling may increase with >30% aromatics.
