(ASK)Polyoxymethylene (POM). is that safe material for vaping?

[Thermopylia]

I bought the Derringer clone online, and it came with 5 different top cap (ss, bronze, brass, black and the white) I didn't realize there are 2 plastic cap until I received them (the black and the white), do you know if they are safe to use? Would the heat from the rda and the plastic top cap result In plastic fumes?

Correct, i wouldn't use plastic top cap if i were you, i highly recommend you not even trying to use it.
Plastic chemicals will get burned out quickly, that is just not healthy.

Personally, I wouldn't use a plastic top for an atomizer.

Max Temp for pom is about 120 Celsius, if you are doing high ohm cool vapes it should be fine, I wouldn't sub ohm though.

I recently read this
https://en.wikipedia.org/wiki/Polyoxymethylene#Properties
and thougt the same as you think. it said that POM melting point at 175 °C (347 °F).. and I dont even know that this product is POM or not.. I just assuming because other forum guy said it was POM/Delrin.

Safety first absolutely

it looks like pretty cool on some other mod with pretty cheap prices. LOL.. still I didn't know.. is that this POM releasing any kind of chemical gas or not while vaping on cool vapes.

Depends on the actual composition and manufacturing process. Personally, regardless of the temperatures used to vape, I would never use a plastic cap on a rebuildable.

 

[JimZet]

You could use plastic drip tip, but not the cap no matter how you vape and no matter what quality plastic is, plastic is plastic, its always chemical. The RBA deck is where all the heat at, and the top cap is attached to it. Its bad.

What do you all suggest if delrin, POM and PC ain't safe? Metal gets hot so I guess glass only? Oh wait glass and metal usually have delrin on bottom or inside the metal so it don't heat up and burn you. Guess just suck on the hole on the top.

 

[JimZet]

Why sucking on the hole? you can use any drip tip. Just use metal or glass top-cap.
You can't heat metal or glass top-cap to the level where it executes gas when vaping, ur mod will not lat you exceed the temperature, or if you have mech mod, u'll feel taht ur mod is so hot u can't hold it xD.
Drip tip is abit higher then where all the heat goes on, so its ok.

All vaping atomizers have a non-metallic insulator between positive and negative, usually made from heat resistant plastic.

Yeah a rubber mostly, i still wouldn't risk using plastic top cap and wouldn't recommend to anyone.

 

[Gramdogg]

hmmm

IMO a quality chemical and heat resistant plastic is safer than some of the metals used.

My point exactly. Glass drip tips have plastic on the connection (all i've seen anyways) and most metal ones are insulated with plastic so they dont get to hot anyways.

Rubbers not reliable..

I'm comfortable with delrin caps for my style, low wattage MTL vaping, saving some weight. It's ironic that these caps are marketed to reduce heat transfer in high wattage setups, where their stability would be pushed a bit.

 

[Gramdogg]

Ok thanks ya'll. Sorry for going off topic about my drip tips. Top cap I'd think would be ok too just because the temperatures it would have to reachto release gas would make metal so hot it would burn you. As stated by jimzet your mod would shut down long before it gets that hot.

true

I'd go with SS as the safest option there. Brass is a metal alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. By comparison, bronze is principally an alloy of copper and tin. However, bronze and brass may also include small proportions of a range of other elements including arsenic, phosphorus, aluminium, manganese, and silicon. Copper is not safe to inhale from at high temperatures. Again none of them should get hot enough to release any of that stuff anyways, but safest would be SS.
