100% polyester white fabric is a slightly transparent fabric. Does this fabric provide good protection to prevent plastic and rubber from drying out and breaking in electronic devices?

Is the sunlight that dries out plastic and rubber in electronic devices any light, even indirect light that is deflected and enters homes?

Does this fabric provide good protection

No.

because? cotton or polyester fabric is better?

Try widening your search slighly.  Instead of searching for polyester, try searching for the polymer its made of.  This is Polyethylene terephthalate. Its often abbreviated PET or pete.  It can be molded into many shapes. Don't know if it will help, but its worth a try.  Good luck!

I don't know of an easy-to-find fabric that is good for protecting the plastic and rubber of devices from drying out

I had read on Google that polyester was good

Why do you think the rubber and plastics are drying out?  What kind of stuff are you seeing?  Thanks.

[marquis]

Quick answer is, if you've got something quick, and cheap, why not try it out?  There are many longer answers if you want longer research answers.  When you get to that point, let me know.

What is the main cause of dryness in plastic and rubber in electronic devices?

[marquis]

That's the problem.  It depends on the polymers used.  Without knowing more,.only general answers can be given .  For example, it could be continued crosslinking, it could be loss of plasticizer, you get the idea. As a first pass, you can try putting a drop of mineral oil on an unused part of the device.  Work it in.  And give it some time.  It.may or may not work.  And it may or may not work on all of the parts of the electronic device.  For example, one part maybe made of black rubber, where it might work.  On the other hand, a drop of mineral oil on some plastics might not work.  It depends on the type of plastic or rubber.  Also note that sometimes they can be dissolved by oil.  Not likely,.but be careful.  That is why you should only go a small drop at a time.
