Not Fairfield County? Time to update your profile....im in California...
You´re right, Kodak has estar-base, but i think only on color sheets. B&W, like T-Max for example, is on PE (polyester).
The last Ektachrome produced in Super 8, E100D, was on cellulose acetate. I hope the new stuff is as well, I like to make cement splices on movie film, polyester requires tape splices.
You might lose that bet but how would you get the info since it's proprietary? I haven't shot any of the "new and improved" Tri-X in quite a while but I don't remember it curling. Many times it's not the film base but the gelatin coat on the back of the film, the "anti-curl" layer.I bet the film base for Tri-X is different from other Kodak B/W films because it curls like crazy...

I beieve ESTAR is Kodak's name for their polyester film base (polyESTAR).

If 120, 400TX is indeed thinner than TMX and TMY-2. The former is coated on 3.6-mil acetate, while the latter are on 4.7-mil acetate. Thickness of both 120 TMAX films is why they were never available as 220 versions, even when 220 was common.Are you thinking of the 35mm or the 120?...
Anyway i´m here to "talk business" and that´s my point:
Consider to put sheet film on ACETATE base, not PET (plastic, synthetic material; in movie film synthetic base is called PET).
Seriously I also have some doubts if this can go right at least.
But if you absolute not willig to give up
with your plan you obviously will be successessful.
Because the market is prepared to want new films to a period a big manufacturer in asia isn't willing to care about film in any way .
with compliments
I just about gave up on sheet film because of dust. Nothing I do - wipe down the darkroom, run a HEPA grade aircleaner for an hour, clean holders and slides with anti-static brush, tried blowing compressed air over the film just before inserting the slide (made no difference either way) - a dust free exposure is just about IMPOSSIBLE. And I've got better things to do than try to spot a negative to print white (which gives one ginormous white spot on your print if you aren't VERY careful) then spot it back, when my 6x7 negs exposures are dust free. Pity, as I like working with the view camera. I do have a 6x7 back but that just doesn't seem the same. If my RZ67 had movements...
We are absolutely not willing to give up. All of us have made tremendous personal sacrifices to get where we are today.
We've had plenty of chances to grab what is left of our sanity and shut the doors - but we cannot.
As we have said before, FILM Ferrania is THE LAST opportunity on Earth to create a self-contained, flexible, adaptable manufacturing base. There is simply no other option, unless Kodak or Fuji were to decide to sell some machines - or another brand were to have the financial means to commission entirely new machinery.
This unique opportunity is far too great to ignore and we will keep working, or die trying.
Hi Harry,
I very much appreciate this impassioned response and I understand the points you make about base material for large format films.
The sad but simple fact is that until we can cast our own base material, we must use products already in the market. With respect to triacetate, we are unaware of any supplier (that we can access) who casts triacetate in the necessary thickness for large format materials.
Obviously, once we finally achieve our fully self-contained status (which remains years away), all of our films will utilize our own triacetate base. But until then we have no other choice.

A few years ago i searched the internet for sheet film and dust problems. On one thread someone said that he did get dust problems with B&W sheets, but not with color-sheets. The website is down now, but when i did my search i found the color-sheets to have acetate-base i think. Or estar doesn´t create and pass static charge... at least someone reported that there´s no dust-problem with color and color had a different base than B&W.
All current Kodak & Fuji colour sheet films are on Estar/ polyester base & have been for at least a decade. Used to be a more random mix - some films on triacetate & some not, which caused a fair bit of annoyance amongst those who used registered masking techniques (triacetate is not dimensionally stable).
Hi Dave,
thank you very much for your answer. I allready assumed that it won´t be that easy, but as long as you consider actetate as base for sheet film when you´re able to do so - that´s all i wanted.
All the best to you, your crew and films made by Ferrania,
Harry
I use the Ilford Antistaticum Anti-Static Cloth and it works great. I've been using the same cloth for a few years now with great results. I wipe down film holders with it and wipe the negatives before scanning or printing. I should probably order a new one soon.Harry,
There are a bunch of different products out there to help you. Anti-static brushes, cloths and liquid film cleaners. I use an anti-static cloth. Works like a charm.
Cheers,
Jonas
During my search back then it made `click`and i started to look about the base material of the film types. Then i did my test with my plastic holders comparing acetate vs. PET and came to the conclusion that PET is responsible for the dust-problems.
. For that matter, 35mm/ 70mm cinema projectors - which largely run polyester base stock - have an in-line anti-static system before the gate.
