Why delrin?

[Gestalt]

I don't know, I thought since I was ordering a plastic drip tip it would feel like plastic. But no, if I bite down on it even a little it feels like biting a piece of metal (not pleasant). It also seems to conduct heat exceptionally well for a plastic. Is that really desirable for a drip tip? Why delrin? What was wrong with the plastic that they make cartomizers out of? That seems like it would be much better...

Even DuPont's website says: "Delrin® acetal resin bridges the gap between metals and ordinary plastics"

I just don't get it. Does someone sell plain old plastic drip tips?

 

[Critter Man]

I imagine someone does, but the issue is longevity. Regular plastic being bitten on by something as hard as tooth enamel wouldn't last very long at all. You aren't intended to bite down on it. Delrin is mainly used for making long lasting tobacco pipe stems. That's why it is used for drip tips.

You sure you've got delrin? Delrin is just a hard plastic. If you bite down and feel metal, and with good heat conduction, I get the impression you got an aluminum tip.

Acrylic or Delrin don't conduct heat all too well.

Can you post a pic of your tip? From what I've seen, almost all vendors carry all types of drip tips. The 4 main materials are acrylic, delrin, aluminum, and stainless steel (from Super T). There's also blown glass tips, but I haven't looked hard for those so I can't tell you who sells those.

Well you could use plastic cartridges, remove the filler and drill through the juice chamber - I did that with a few whistle tips. Delrin, however, is food-grade, heat resistant and highly stable and well suited for such a purpose.

I'm pretty sure its delrin:



Btw, I'm not planning to chew on it or something, but it is unpleasant when it does come in contact with my teeth. Maybe I'm the only one having a problem with this. Its not like its the end of the world if I have to use delrin, its just not really what I was expecting or really hoping it would be.

Where do they sell the acrylic ones? That sounds a bit more like what I was expecting.

I use the soft rubber silicone tips from MFS.

 

[CANCHASER]

What is mfs

 

[trouble2k]

MFS is probably MyFreedomSmokes.com

I searched for ya and found this. Hope it helps. My Freedom Smokes

Thanks, those silicone ones look like they will do the trick. That gives me an idea though. Maybe I can silicone coat my delrin tips...

 

[Deeked]

You probably can coat them yourself. They make all kids of coating material for stuff like tools to boots. Give it a shot and see how it turns out.

Those look pretty sweet. I couldn't remember where to find them. Thanks for the link.

As to why Delrin it is one of the very few food grade plastics that is strong enough to withstand repeated biting, resist heat deformation and is machinable.

 

[dormouse]

LiteCigUSA.net has plain clear colored plastic ones. They are still hard plastic.

 

[lolady]

Because it sounds like that embarrassing cousin we've all got at least one of.

Your sister's wedding, the guy in the beer hat... Yep, that's Cousin Delrin...

If he ever gives up his unfiltered Luckies for e-cigarettes, he'll start a band, and call it "Delrin and the Drippers."

TheEcig.com sells the pyrex glass drip tips, they are $15 and very nice, John Vesey is hte owner.

Also, in reference to the OPs other queries, Delrin has a crystalline structure that gives it many metallic properties. DuPont actually advertises it as a better alternative to metal in many circumstances.

Dormouse is right Litecigsusa.net sells good plastic and delrin tips, I use them and they are both very good, and Provape sells some too, SuperTmnaufacturing selss good drip tips that look like tiparello types, flat at the mouth end.
