The source rates silicone for only 21 chemicals, far fewer than the other materials. A chemical that is missing from this table has not been rated; that does not mean silicone resists it. For seals, compare EPDM, Viton (FPM) and NBR, which the source rates for more than 800 chemicals each.
Chemical classes were assigned by this site, not by the source. Mixtures and trade products without a clear class are not counted.

* = estimated rating in the source, given without a temperature. L = risk of pitting or stress-corrosion cracking. Only chemicals with a rating for this material are listed.
Medical tubing, implants, pharmaceutical closures
FDA-grade seals, bakeware, food processing
Oven seals, exhaust gaskets, lighting seals
Silicone may degrade when exposed to:
Tip: For fuel and oil resistance, use NBR or Viton. For aggressive chemicals, PTFE is preferred.
