why she began to melt.?

Is the wire copper? If it is, the coating on it might'vbe been damaged and it might be reacting with the TPE; I'm sure I read somewhere around here that copper and brass and stuff has that problem?

On finger begin to melt, only one, she is a WMDOLL 2018.

What I do I cut?

For my next Doll I think take Silicone as my first Doll, TPE low cost china is a very bad material... Moisture easy, no bacterial, to melt sometime, reactive to other thing cometime, oil all time and manufacturer don't know if we do it or not, oil enter, but never go outside...

TPE is a low cost material, 3 years lifetime, silicone platinium is about 5years lifetime, for me stop this bad material TPE....

Don't overuse TPE repair glue if you're trying to fix your doll. It will melt down the TPE. Please use Super glue If you want to glue the nail on the finger. Take good care of your doll.

Hi, ADHERAQ777

We noticed that the situation is rare.

The TPE material contacts conventional items (items without excessive chemical components) and will not melt at regular temperature.

Could you send us a video for it, shoot as completely as possible about the situation. We will follow up with you later.

Thanks,

WM Group

Is this possibly a reaction to either the nail polish or an earlier application of nail polish remover?

I agree with this, the pics from the melting phenomenon appear to start in one spot and work their way through as if started by a chemical reaction. It would be nice if there were a legit chemist here to say what chemicals could affect TPE so we could watch for them in the products we use.
The doll that started this thread really looks to me to have had a reaction with a hair care product or the material of a wig, Until we know what things start the reaction it would be safest to store TPE dolls buck naked, I don't even use cloth against mine in storage, just plastic sheeting over the pillows they lay on to avoid having the oil weep out.
Regardless, it does look like once the reaction starts it spreads through by physical contact which is why I suggested amputation to remove back to the good TPE before the reaction continues further. We know enough now to reconstruct and repair TPE with readily available tools so something like that finger could be rebuilt by removing a small section of material from inside the doll.

My god, that looks terrible, is it because of the high temperature?

Only use Soap on Hand and Oil, never other thing

I have cut.

Reaction seem to be stop now.

I bet you saved her, the reaction could have been from anything she came in contact with. That's why I wish we had information on what could react so we know what to avoid.

If the melting doesn't start again perhaps WM could send a TPE block to aid in repair, could even be a good excuse to upgrade to articulated hand skeletons and make a little lemonade from lemons..

Is the finger wire copper, or a copper alloy?

You were looking at the green color of the other pic

So, if silicone reacts badly contacting TPE, how do they swing mounting silicone heads on TPE dolls to sell?

And, is the process the same in reverse? Does TPE damage silicone?

Really was set on a particular girl, but pretty sure I'll stop and look for a silicone now if they last so much longer...

seagull · Post by **seagull** » Wed Jul 13, 2022 6:02 am

Heads are usually a harder type of Silicone, practically no Silicone oil to get mixed up with the softer TPE
I believe the advice is still not to store Silicone & TPE touching each other for lengthy periods
From anecdotal accounts on this forum, mixing two dissimilar free oil constituent substances together has not had good outcomes for a number of years

This thread is truly nightmare fuel but very interesting nonetheless. Not showing it to Miranda, of course!

And credit to WM for showing up and replying!

Huge props to WM for joining the conversation. This is not specifically a WM issue, it is an overall TPE issue, but if WM stands up to take notice, then they are the vendor to back.

My exact thought when I saw their post

Been looking into what could have caused this and in reading several pages of chemical analyses and production papers on TPE use in industry, all I could pick up in most of this was, HEAT destroys TPE. As little as 80 degrees f. can start the degrading process. TPE is a silicone product that is made from silica sand and chemicals to cause a elastic chain of the molecules and it is forced into molds and then cooled. After cooling it has taken the shape of whatever was the molded design. BUT, TPE can be reshaped with the application of heat again, it can even be recycled. (read that some dolls are in fact made with recycled TPE and they tend to fall apart faster due to improper mixing).
Your photo's are very disturbing, we pay a lot of money for these dolls and hope they would last quite a few years.
TPE is used for prosthetic limbs and if the polymers breakdown after a few years from ozone and heat, this could be pretty expensive so I am not absolutely sure that I did get to the true answer as to what caused this head meltdown. I would hope you still have this "Face glob" and could maybe send a sample of it to doll manufactures if needed after you contact them and ask what they think.
