Viton is often used as elastomeric seat in butterfly valves. Viton is
know to be restistant to 'difficult' chemical media.
However, in many chemical resistance lists the use of Viton is not
recommended for hot water applications or steam service.
What is the specific danger of hot water / steam to Viton ? Does it
restart the curing process ? Does it attack the cross linked polymers ?
What is the fysical result ? Does it increase hardness ? Does the viton
become more brittle ?
thanks for your help !
