Default Mylar Thickness ??

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...

Thinner. Saran Wrap (which no longer contains Saran!) typically runs 2 or 3 mils.

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?
