What is the difference between modified polytetrafluoroethylene and polytetrafluoroethylene gaskets? At atmospheric pressure and a working temperature of 35 degrees, which gasket is suitable for sodium hypochlorite solutions?

I’ve only heard of expanded PTFE; I’ve never heard of modified PTFE. For sodium hypochlorite, a soft PVC pad is sufficient. It’s cheap and economical; currently, the chlor-alkali industry is facing tough times, so it’s better to save money, haha.
