Wait a minute. PTFE does what?

Wait. That doesn't make for a good laser armor... Do you have any idea about anti-laser radiator armor?

I believe plating everything in PTFE would get around many issues ;p Melting Temperature melting temperature of PTFE is about 600 K right? For Cryogenic fueltanks maybe but for anythig over 600 K very doubtful but so is storing flourine in Boron tanks. Also All Hail mighty Boron.

Radiator reactivity is something else - my response was for cryogenic fuel storage and injector finishing. so is storing flourine in Boron tanks. Plate with PTFE

Just asking slightly off-topic question.That aside, I found a website that lists boron's reactions WebElements
And some other reactions ChemGuide

Plate with PTFE Ahh but I belive that you stated in your original post to plate everthing in PFTE. So I was confused. The only area of application of PFTE would be fuel tanks.

And any other surface coming into contact with corrosives under 600 C/870 K.

Last I checked (read on Wikipedia) I'm pretty sure Aramid Fiber when oxidized a bit tends to lose its amazing balistic stopping properties after 2 to 3 months.
Not sure if it's as relavent as something like Flourine, but still.

Not sure if it's as relavent as something like Flourine, but still. Aramid is Nomex, and has mediocre anti-ballistic (but excellent anti-thermal absorption) properties. Para-aramid is Kevlar, and has good anti-ballistic properties. Also, we are in space, and there is no pesky oxidation going on! Otherwise our 1700k boron thrust bells and 3500k carbon thrust bells would burn.

imagine what happens when it runs into flourine or FOOR or FOFF

And any other surface coming into contact with corrosives under 600 C/870 K. PTFE melts at 599K (326 degrees C), not 600 degrees C. Also that number is irrelevant because it starts to break down into fluorocarbon gases at 533K, so unless your PTFE object is only expected to last a few minutes at best the breakdown temperature is the working limit.
