Edit: So after a bit more digging, it seems the "insert" between glass and steel band on the iPhone XS is present for the front only. There isn't an "insert" between the back glass and steel band of the phone. This is different from the iPhone X, which had this material for both front and back.

Does anyone know, definitively, if it is plastic or rubber? Or some kind of composite?

Same question for the "insert" or "buffer" between the front glass piece and the steel band.

Appreciate all input :)

Plastic, I accidentally melted one while during a back glass replacement.

It withstands heat a lot better than plastic but it still is.

Hi Lekro, thanks for your reply :)

Would you be able to confirm? What makes you think it's plastic and not rubber or a composite?

Thanks :)
 
Can’t say for certain but traditionally with all iPhones and with all other phones from other manufacturers it has always been referred to as a plastic antenna band or buffer, especially in teardowns and repair guides, I’ve literally never heard somebody call it something different.

For the intended usage, plastic does seem to have the ideal properties.

Because the stuff I posted. I heat the chassis up to 270-300°C during the back glass replacement, rubber would melt away.

Okay OP, I'll bite, may I ask as to why you're so intrigued about what type of material is present? I'm just curious...

Rubber would be soft. And compostite doesn’t melt, it burns.
Probably thermo injected plastic

Thank you guys :) Would your comments apply to the "insert" or "buffer" between the front glass piece and the steel band too; is this material pictured below a plastic, rubber, or a composite? @Lekro @maerz001

FlippyGonnaSnap you're mostly-right; indeed, from what I've see at least, most people refer to it as a plastic, though I've seen at least two instances where it was called a rubber. I'm just hoping to get more clarification/input from more people. Thanks :)

Fair question, though if you were expecting something interesting I'm sorry to disappoint. Main reason is..I came across this aftermarket(?if it's the right word) spray-on nanocoating product marketed as safe for mobiles - not just the screen, the frame too - but it's officially only applicable on plastic, metal and glass. Thought it'd be nice to be able to protect and better-preserve the phone; I'm on prepaid and use my phones for an average of 5 years. I'm admittedly kinda OCD, so I'm tryin' to be careful. My phone actually hasn't arrived yet.

I know only Apple truly knows exactly what's on/in their phones, but Apple's online chat support couldn't help much. Approached
Apple Support on Twitter, no reply yet, and I'm sadly not hopeful.

Anyway, if anyone's got any insight, please feel free to share. Thanks and have a nice day! :)

Oh okay, I got you. I'm the same way I like protecting my phone as well. Me personally, I don't put much faith in those type of coatings especially after watching YouTube videos on them. But that's just me. What about a wrap? Maybe that would give you some added protection.

Okay, ..I've seen talk of a rubber gasket for the iPhone's screen, that's proportedly for water resistance. Is this referring to the "buffer"/"insert" I'm interested in? I thought the XS relied on adhesive to seal its display; rubber gaskets for other stuff like buttons and lightning port?

My bad for bothering everyone.. appreciate all comments > <

Are you referring to liquid screen protectors like Spigen's "GLAS.tR"? Yea, I'd agree those aren't very good. The company of the product I'd like to try seems more "legit" though; they have both industrial and retail catalogues. Plus they say you can use it on the steel band too so it's like almost a 360-degree thing. Either way, after the coating cures, I'll be leaving the phone in a LifeProof or something. Maybe I'm over-doing it, but...yea.

One thing to keep in mind, Apple isn't very fond of these type of coatings, so doing anything like that may give them a reason to void the warranty.

Makes sense. Thanks for the heads-up. :)

Either way, I think it'd be nice to know what material(s) the 2 things are composed of. So it seems the antenna lines are plastic. What about the "insert" or "buffer"?

Appreciate any insights, people. Know that it'd really help me, or those who have rubber allergy.

Sincere thanks for your time and kind help > < :)

Anyone with any idea what this "insert" is made of? Plastic like the antenna lines? A composite? Rubber?

The plastic between the screen and body has been there since the iPhone 6 and was never present between the back glass and stainless steel on the X.

There is something between the back glass and steel band on the iPhone X. Not sure if it's the same material/composition and purpose as the insert on the front (so you could be right in that it's not plastic), but there is definitely something there. Refer to 3:30 in the following video

Anyway, I'm interested in the XS, not the X. But good to know..

But thanks for your input! So the insert between the front glass and steel band is plastic? For sure? :)

Oh I see what you meant. I didn't know the X had it on the back as well, but doesn't look like the same material as the one on the front to me.
