Standard plumbers tape - ptfe.
It's rated to ~500*F and melts around 700*F I believe.
In comparison standard solder melts at around 400*F, and tin melts at ~450*F.
I wouldn't use teflon tape w/ a suppressor, but otherwise it should be good to go excepting weapon destruction testing and/or other multiple mag dumps at near full auto rates of fire... It really doesn't burn or displace when hot, just discolors.
*Also, the VZ2008s are coated in teflon too, so you're ultimately more likely to burn that under your handguards than you are at the muzzle.
