I have a roll of Mylar I think it's somewhere between 3 - 5 mil (might be way off) on a large roll (about 5' wide by 10 ~ 20', once worked at a screen printing chemical company) and wondered what thickness is optimal for esl diaphram?
Thanks in advance,
Eric

0.25 mil is optimum; 0.5 mil is usable but will generally show a rolloff in the top octave. Roger West found that out the hard way...
2 MICRON = 2E-6 meters thick Mylar is used in the Sound Lab ESLs.
4 MICRON =4E-6 meters thick Mylar is frequently used in DIY, as it is more robust and can withstand manual application techniques of a high resistive coating. 5-6 micron Mylar is another common ESL thickness.
1 mil = 25.4 microns

Dow sold the brand name for the film (not the resin) to another company, who immediately subbed a cheaper resin. Of course the excuse was to make it more "ecological." Sure, you bet. Saran resin is still PVDC and still Dow.
so is it 0.4 mil or 4 mil?
"4" used as example only
what i have is about twice the thickness(may be more) of saran-wrap. would that be unusable?

Yes, it is unusable as ESL material. I was trying to point out that it's too thick by an order of magnitude.
But it will do fine for wrapping your sandwich.

Hey SY thanks for the info. I was out in the garage checking it out and yes it is THICK, I can accually crease it. Oh and please leave the Sharks alone, okey-dokey!'😀'
Someone Help!
I've been trying to find aluminized mylar in about 1/4 mil or even thinner for a while now.
Where?

Capacitors
Basically I'm having fun with making my own:
1) Capacitors
2) Microphones
3) Electrostatic speakers are starting to look pretty $%@##$% interesting now too...
Trying to find aluminized mylar has been a pain in the butt sofar. I've tried (with no response yet) astronomy clubs, hobby shops, and even wrote to an independent space exploration program that is working on solar sails asking for help finding a supplier.
I called Peluso Microphone Lab, and the owner said he'd bust me off a sizeable chunk of sputtered mylar. I think he got the idea that I was going to be his competition eventually and kinda backed out. I shouldn't have sent him my CAD workups of my designs...
