new accufilms are crap

[JMN]

Why do some of you use Arti-fol for contacts, but something different for occlusions, typing ribbon, Tanaka paste, Butterfly Silk?
Does the Arti-fol smudge, or leave false positives?

any effectively 2d material can leave false positives over 3d surfaces.

Does the Arti-fol (or todays Accufilm) smudge, or leave to much ink false positives when checking the occlusion?

Those are the freebies those cheap exocad buggers crammed into their Labday '95 bags before they hit the open bar at Sirona World.

Arti-Fol is available in ultra thin 8 micron. Its not going to take you out of contact, so glaze will be real close and wont take more than a super light touch to correct.

Silk ribbon is more flexible when adapting to occlusal shape, plus it much thicker...closer to .28mm.

I did get a response from Parkell, seems that all US manufacturers have been forced to change the way they manufacture marking films:

Hello Sir,
Thank you for your email. I am sorry that you are not happy with the new version of Accufilm. However, there seems to be some mixed feedback on this product as we have had some people say that they do not like it, and others say that they have found the product to meet their standards. Original Accufilm film used to go through a 2-step, heat/cold process. This change of the film occurred through the U.S. and Canada (from a majority of film companies) due to a request from the EPA to collect the MEK that was being released from the solvent ink used in the cold process for environmental concerns. In order to comply with these regulations, we had to switch to a heat/heat process which did not hold up well with the original film. We are now using a Polyester film that is highly durable (but does not stretch) which can withstand the heat/heat process. There are some companies that claim to have similar products to “Original Accufilm”. However, these are companies outside of the U.S with very little, or no restrictions to pollutants. If they are a company in the U.S., then they are being made illegally. There is NO current manufacturer in the states that admits to still using the now illegal manufacturing process used to make the older style of Accufilm. Our goal as a company is to be more environmentally friendly. We are exploring other methods of being more environmentally friendly as well, including packaging, office usage, energy use, etc. I hope this reply helps to better understand the changes that were made and the reasons why. If you have any questions or would like to try a sample of the newest version, I would be happy to have some sent out to you. Thank you for your input and your time. Have a wonderful day!

And hear I thought that it was because they were going cheaper, and not due to epa concerns.

Thanks much @erykd1 for posting that. Answers many questuons.

MEK for those who don't know is MetylEthylKetone. The main smell in die sealers and many die paints. Euro 0 angstrom die sealer and permasoft sealing are both almost pure MEK.
