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:
