Which has better performance, Teflon gaskets or RPTFE?
Reply #2 2017-02-28
The ones behind are the enhanced versions. What do you mean by performance being good or bad?

Sealing performance: what are the m and y values for Teflon gaskets?
Reply #4 2017-02-28
It’s specified on the flange standards. HG20592
Reply #5 2017-02-28
It’s hard to say! Each has its advantages

RPTFE is a reinforced version of polytetrafluoroethylene; according to HG/T 20627, PTFE can only be used in environments with a temperature range of -50~100°C at CL150 pressure, while RPTFE can be used in environments with a temperature range of -200~200°C at up to CL300 pressure℃

Very knowledgeable about the performance of gaskets, great!

Are Teflon gaskets polytetrafluoroethylene? Yes, paintings definitely can’t compare to RPTFE.
Reply #9 2017-03-01
What is the basis for stating that RPTFE can be used at 300 degrees?
Reply #10 2017-03-01
It’s a CL300, so there’s no problem
Reply #11 2017-03-01
It says 200°C on my post; the standard number is indicated there
