I have the original Samsung Tab S5e cover for my Tab S5e tablet. The good news is the tablet works great.

But I have a problem with the Tab S5e Cover, some call it sticky rubber, but I read some about production of artificial rubber and real rubber, and I think it is a procedure known as ' Reversion '. This means what goes right during production of the (semi)synthetic fabric inverses the fabric. Reasons are due to for example Sunlight, Oxygen or normal Air with normal Humidity or just your hands and fingers.

The original Tab S5e Cover is probably mainly made of a Thermoplastic elastomer.
Code:
Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties. While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, by injection molding. Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials.
https://en.wikipedia.org/wiki/Thermoplastic_elastomer

Since this cover is original and only a few months on the market, this natural process of Reversion should not happen at this product age. Products like this should for example show this only after many years or not at all.

The problem described in a practical situation, I take the tablet and open the Cover, I hold the tablet with the hands around the Cover. At first I notice nothing, but after an hour it is like as if the Rubber like Cover is melting and releasing some sort of glue, hence it at places where I touched it or hold it, feel like the backside of a poster sticker. These are products from fabrication probably reacting with even the small amount of heat and moisture that is continuously released from human hands.

The annoying thing mostly is after using the tablet my hands feel as if like under a glue sticky substance. I looked up what substances this could be and found after reading about Plastics and Elastomer this:

Code:
Plasticizers (UK: plasticisers) or dispersants are additives that increase the plasticity or decrease the viscosity of a material. These are the substances which are added in order to alter their physical properties. These are either liquids with low volatility or solids. They decrease the attraction between polymer chains to make them more flexible. Over the last 60 years more than 30,000 different substances have been evaluated for their plasticizing properties. Of these, only a small number – approximately 50 – are today in commercial use.
https://en.wikipedia.org/wiki/Plasticizer

This substance that sticks on your hands should be removed before you eat.

Since I searched on the internet if other people have this problem, I found people with Laptops, Computer Mice, Computer Keyboards having these kind of problems too. They give each other advice how to clean it, etcetera, but I concluded that I should not do this. I should return it, but now is the problem I face clear.

Does swapping the Original Tab S5e Samsung Cover result in just an identical which then has the same problem? If so swapping it by sending it back is not the answer to this problem.

I called Samsung and they told me to swap it. In return I told, if I swap it now ( It was 24th of July 2019 and 33 degrees Celsius inside, 40 degrees Celsius outside ), wouldn't I have it swapped with an original from the same batch having the same problem? And I explained my Note 2012 tablet Original Samsung Cover never had this problem, and no other phone cover I had has this problem. They told me it was unfortunate, but no clear answer. It is logical that if I at that time would return it, it would be swapped from a same batch and same production month era, I would probably end up with the same problem.

Anyway I have to return this Original Samsung Tab S5e Cover, but what do I have to do? Is this just unfortunate coincidence? Or do all production batches of this Cover have this problem? And also if this happened so fast already, what will it be like in next year?

At local language forums I cannot find others who bought the original cover except for product reviews at a few websites, I could find under 20 reviews, with 4 stars average I suppose. But this problem is too complicated to put in a review.

You can find many results by searching a search engine for ' Sticky Rubber ' and you will find for example this, beside many people complaining about their computer products having it at products like a mouse, a keyboard, or a laptop.

I have once in the past had this too with a Mouse which I replaced with a new one. ( But not the same type. ) It is also happening in a product range of many brands, like Logitech, Microsoft, Hewlett Packard.

Cleaning procedure is not an option, since it is new, and it should not happen within such a short time. Actually the Note 10.1 from 2012 tablet Cover I have original too, proves that it does not have to happen at all.

The problem I also see, is you actually need to use the Tab S5e Cover to make the problem appear. Just touching the Cover doesn't make it clear. So if I send it back they might say, we see nothing wrong, they touch it and return it e.g. But this original Samsung Tab S5e cover I have does slowly react within hours with your hands and fingers.

EDIT1 This is placed in the wrong section of XDA and will be probably moved. Since this is not about developing software but the Cover case.
EDIT2 This might indeed be about development of a manufacturer, but related to hardware supplementals, a Moderator was asked to give it the right TAG.

Appendix: This tablet really needs a case to give it weight and something to hold, I don't experience any Wifi problem since my Router the ASUS AC66U has Beamforming. I have the 6GB Ram 128GB storage version. Wifi range is similar like 2012 Note Tablet and only little less than Galaxy S8 at 5 GHz Wifi. Make sure to have your router to have Beamforming enabled. And MIMO 2x2.

I have had my cover since launch day and do not have this issue. I usually take mine out of the cover when I use it for any length of time though. I'd definitely swap it out.

Ambient temperatures
May I ask what ambient temperatures you had since you got it? I will convert the temperatures into Celsius and Fahrenheit. The cover started feeling like a chocolate bar at 26 Degrees Celsius ( 78.8 degrees Fahrenheit ) at ambient room temperature. The first heat wave became 33 degrees Celsius inside ( 91.4 degrees Fahrenheit ). Outside it was 40 degrees Celsius ( 104 degrees Fahrenheit )

Although it still feels as if holding a chocolate bar, but without anything visible at the cover itself, provided I use it more than half an hour holding it.

Whatever is released on my hands is not visible, but describing it as if having hold a chocolate bar melting is the best description.

I indeed want to ask the reseller to swap it through Samsung itself, since I hopefully just happen to have a coincidence batch that does not fall into Samsung its standards.

If it would have been winter and snow outside, this might not have happened. Also I think about how it was shipped, perhaps in a very hot container, to my country.

The inside of the cover feels like the inside of my Galaxy S8, so the tablet itself is perfectly safe. At first I thought it might have been glue since inside the Cover are magnets and they must have been glued. Then I read how artificial synthetic rubbers are made and did read what I posted in the opening post.

Explained in opening post is also why during the heat wave I did not see swapping at that time a solution. I really hope to having a good version of this Cover, since it works great, and I don't use the tablet without it. The tablet is so tiny in weight despite it having a 10.5 Inch screen.

Ambient temperatures is what I would like to ask as said, Fahrenheit to Celsius or the other way around I can calculate at internet.

I have had it around 75F or 24C for 99% of the time. That could be the problem causing it to "melt" a bit...

Production date of cover: 2019-04-11
S/N RF7M40Q4XTKJCS

I have scheduled it to ask for the same cover, but from another production date. Also I do think that if it were winter from the beginning since I had this original cover, it would have had time to harden out inside for many days. My original cover from the Note 10.1 from 2012 was bought e.g. in December 2012 during winter and I did not have it, even not today.

The temperatures have dropped, inside it is now 21 Degrees Celsius, it is however still is existing, but not visible with the eye or camera, the material seems well still.

Samsung also told me to swap it. The reseller contact said I could send it back and what option I would like. That being said,

* Same cover, by manufacturer warranty
* Different production date

I use the keyboard cover. No issue at all.

I had the standard cover, since I use the tablet for media consumption only. I asked especially for manufacturer warranty because Samsung makes the originals. In my country the cover was later than the release of the tablet itself, hence I was or am an early adaptor here.
