*Delrin*

[Jason-Tank]

Can anyone tell me if delrin would hold up to the heat of a genesis coil set up? if let say the deck of the atomizer was delrin and cap was delrin? if someone knows that would be awsome. its hard to find information like that on google lol

Thanks in advance

it should be fine as long as the coil isn't directly touching the delrin and it's good delrin, like machine grade.

Looks like it has a melting point of around 175 C.

as a note, heat deflection on standard delrin is 336F at 66psi (this means if it's got 66psi of pressure on it and reaches 336 degrees it'll deform) and has a melting point of 347 degrees F.

A dry fired coil can hit excess of 500 degrees F, the boiling point of PG (i.e. when it'll vaporize) is around 370, that doesn't mean anything within a few milimeters will get to that temperature though. When the juice vaporizes it rapidly cools the coil, average temperature I've seen on a wet coil has been ~180-190 degrees vaping a 3ohm coil at 5v. It's not going to get to terribly much hotter than that even at high wattage vaping so delrin "should" be comfortably within the zone so long as the coil isn't right up against it and you aren't dry firing it for long periods of time.

That said, chain vaping in a gensis will impart some heat to the mesh wicking, but consider this... a genesis style atty usually has a metal cap/chamber bottom. Metal that is a much better thermal conductor than delrin. If the cap was being exposed to 330+ degrees people would be burning the hell out of themselves constantly.

Delrin should be safe.

Delrin deck should work reliably and without any smell if you insert into wick hole a tube, say ceramic or glass (ideally) or even metallic. And use massive contact ends.

My delrin/polycarbonate genesis is nearly done. I've put a piece of 2.5mm ID stainless hypodermic tube in the wick hole to shield a bit of the heat.

Thanks everyone. is machine grade "acetal"? or is it all the same?

 

[Switched]

yup same

 

[Lance_Wallen]

"generally" the same. Pay attention to the specs and not the name. Different manufacturers have different grades of product. Duponts machine grade "Delrin" can have different characteristics than generic machine grade "acetal" they are the same thing technically but make sure you read. Some acetal that's labeled as machineable has a lower melting and heat deflection point as well as lower rigidity. It's usually minor but my personal opinion is "only the best when it comes to something I'm gonna shove in my face."
