ASEPCO’s Viton Diaphragms

Excellent heat and chemical resistance


Viton® (trademarked by Dupont) is a class of fluoropolymer elastomer (synthetic rubber) commonly used in O-rings and other molded or extruded goods. It is well known for its excellent heat resistance, making service temperatures over 150° Celsius possible.

Viton is often used because of its excellent chemical resistance. The performance of fluoroelastomers in aggressive chemicals depends on the grade of the elastomer.

To get specific chemical compatibility information about Viton and other elastomers, we suggest that you refer to these excellent sites:

Dupont Elastomers – Chemical Resistance Guide
Cole-Parmer Chemical Compatibility Database
To get more information about Viton, look at some of the suggested resources on the Datasheet & Resources tab.

Viton’s chemical resistance is summarized below.

Good Resistance

Hydrocarbons
Many aggressive chemicals
Diluted acids
Weak alkalis
Mineral oils
Aliphatic and aromatic hydrocarbons
Chlorinated hydrocarbons
Poor Resistance

Ketones
Acetone
Esters

Specifications

ASEPCO provides diaphragms created with a number of different materials. The materials vary with respect to heat-resistance, chemical-resistance, and durability. The table below shows basic compatibility information. Please do not use this information as your sole method for determining whether an elastomer is right for your specific process. Before using any elastomer in a process you should verify its compatibility with an elastomer expert.
