So, I have noticed that several different rda manufacturers are using Delrin as their choice insulator. (Oops, my cat attacked my phone before I was finished the post). Anyways, I have noticed several posts on different forums mentioning the burning of the Delrin insulator and yesterday a friend of mine melted his, in his pocket with his mech...

I just wanted to make fellow Vapers aware of the danger when vaping with Delrin parts. Delrin does release formaldehyde at high temperatures. I really want a big block but I'm not sure I'm willing to risk my health. I know that it's far enough away from my coils not to really worry. BUT, I've just heard and now seen that there is a real possible health risk.

BTW, I do frequently machine Delrin and have extensive experience working with it. I take extra precautions to protect myself. By far one of my favorite plastics, it's amazing!I'm just not sold on this application.

I've seen this same discussion on reddit and someone actually did the research into finding what the actual temps are for various coil resistances at 4.2 volts.
Op- do you have the temps that Delrin starts to melt? That would be helpful info I think. An insulator melting on a mod that was constantly cooking in a pocket is different than an insulator melting while vaping. A couple second pull on a .6 cool I would think wouldn't be enough to destroy Delrin correct?
But if an atty is left to cook over an extended period of time (like a pocket fire) than I would assume that the Delrin is the least of the issues correct?
For those building ridiculously low subohm coils I personally would avoid the stuff anyways. But I also would personally avoid anything below .5, but that's just me and my vaping style.

It depends on how low the delrin insulator is to your coils.
I own a Plume Veil clone, which has an adjustable derlin insulator, and as long as you don't have it close to the coils, it should be fine. I know I've seen a few posts/pictures on it, and really the only times there are melting issues is with user error. I've been able to go as low as .4 with my Plume Veil with absolutely no issues. As long as you play it safe and smart, it shouldn't melt.
Just from my experience :)

i recently bought a big block RDA. Just swapped out the Delrin tip w/ a SS wide bore. works great. don't let the Delrin tip keep you from getting one, it's an awesome atty.

Likewise, didn't care for the delrin DT with the 2 angled holes. It seemed a bit restrictive.

I'm not familiar with the big block but the ops fears are based on an insulator not a drip tip if I recall correctly.
I know that rda's get hot to the touch when you're firing them for extended periods of time but it would take some serious serious heat on it for a heat high enough to melt a drip tip. I would think that the insulator would be done (closer to the heat) before a drip tip was effected.
Again not an expert but once an insulator goes aren't you looking at a much bigger safety concern than what the insulator is doing?
