Guideline only. Values and ratings are representative at ambient conditions and are not a warranty of performance. Actual results vary with temperature, pressure, concentration and exposure time. Validate for your specific application — our engineers can help.

Choosing a seal material for Hydroquinone

The table above rates every common O-ring elastomer for service in Hydroquinone on an A–D scale. A is Excellent, B is Good, C is Fair (test before relying on it), and D is Not Recommended. An X indicates insufficient published data.

For Hydroquinone, the strongest candidates are Hydrogenated Nitrile, Fluorocarbon (Viton), Perfluoroelastomer, Silicone, Fluorosilicone, Natural Rubber, Styrene Butadiene, Butyl. These ratings are representative at ambient conditions (~20°C). Compatibility shifts with temperature, concentration, pressure and exposure time, so always validate the material against your real operating envelope before committing to a design.
