thanks Julius , but in terms of temprature or flow velocity it could have effect ,in practical we got some degridation of PTFE , visually it looks chemicaly reacted but no eviedence support .

possibility of swelling PTFE by molten dinitrotoluene??; reacting of dinitroluene with inpurities or additives in PTFE?

Manfred Elend

The PTFE is no problem, this is chemically stable. But dinitrotoluene (DNT) is not stable. This is an oxidizing agent. We found autooxidation of TNT at room temperature. For DNT it is also possible at lower extent.
