Talk:Tyvek

Untitled
I am curious about the "ingredients" in Tyvek. Specifically, is Tyvek an efficient substitute for more traditional ends to the same mean in terms of embodied energy, etc.? —Preceding unsigned comment added by Hogjaws (talk • contribs) 05:15, 6 October 2007 (UTC)

History?
I would like to see some history of Tyvek. When was it invented and by whom? What was its original purpose? — Preceding unsigned comment added by Navstar (talk • contribs) 17:47, 22 January 2006‎

Originally Tyvek was a housewrap material. It is now used in many fields, including roofing. Tyvek was discovered in 1955 by DuPont in the USA.

I am the grandson of Walter Steuber. He developed Tyvek® in spite of what the DuPont history page says. I can back this information up with patent numbers. Here is what I posted to DuPont's FB page:

I would like to point out some egregious factual errors from your website:

http://www2.dupont.com/Tyvek/en_US/products/about_pgs/history.html

Jim White had nothing to do with the invention of Tyvek®. That honor belongs to Walter Steuber. He has a number of patents with his name on them from when he worked at DuPont:

24,691 2,441,170 2,813,775 2,929,804 2,935,372 3,044,990 3,051,545 3,169,899 3,242,120 3,421,181

A brief account of the discovery of the material that became known as Tyvek® is this:

"First, Jim White, who was my lab partner at the time, had absolutely nothing to do with it. The first person to see the stuff was Herbert Blades. He had a small pressure vessel containing a hot solution of HDPE. He opened the valve just to get rid of the solution and it squirted out in the form of a sheet. He called me in to see it because it was so novel, but he did not want to persue it because he had something else he wanted to work on. So I said I'd like to develop it, and did. Something like that string of happenstance seems to mark most inventions."

I would be most grateful if you could fix the information on that page and have it propagate to wikipedia. Walter turns 98 this year and it would be nice for him to see this.

Thank you. David Steuber98.225.209.235 (talk) 04:36, 7 June 2014 (UTC)


 * David, I'm the inventor of the first origami Tyvek wallet. I was recently recognized by DuPont in this video about the invention of Tyvek Wallets: https://www.instagram.com/reel/CfBT0NIM1-J/

I came across a video interview with Herbert Blades (who was also apparently instrumental in commercializing Kevlar) from 2014 in which he talks about the early discovery and development of what became Tyvek;

https://digital.hagley.org/2014249_20140819_Blades

The Tyvek portion starts at around 10:20 in the video. He indicates that Jim White saw the material before he did, but that Jim White was not the first person to see it. He said that it was brought to Jim White by Louise Jones, whose husband, Dick, was in the lab with the pressure vessel (which sounds like what was mentioned above by Walter Steuber). At about 14:17 in the video, he states the Louise and Dick never received any credit for that.

There was also a letter from a Dr. Peter R. Lantos posted online by the Philadelphia Inquirer on January 10, 2016:

https://www.inquirer.com/philly/blogs/inq-phillydeals/364799621.html

It describes the initial discovery in similar fashion to Herbert Blades in the video interview.

Given that there seem to be three conflicting stories (and lack of a proper secondary source), I will remove the mention of Jim White from the article for now.

Water Resistance
According to many articles, tyvek is not waterproof (although this entry says that it is.) It has limited water resistance. I don't know at the present time, if there is a type of tyvek that would be actually waterproof. http://www.spraytec.com/tyvek-suitsSomaeye (talk) 22:52, 3 May 2012 (UTC)

Archival Storage?
I've read that some forms of Tyvek are acid-free and thus suitable for long-time archival storage of documents etc.

Is this true of the widely-available Tyvek envelopes or only higher-grade Tyvek sold by the roll, specifically for the purpose?

The lower-grade Tyvek is coated with an anti-static chemical to speed up the manufacturing process but there seems to be some debate on what effect this would have, if any, on items stored in it.

Any further information on this would be greatly appreciated. — Preceding unsigned comment added by 198.99.32.5 (talk) 02:18, 5 October 2006‎

moistureproofing
I would like to use Tyvek for wraping a basement foundation instead of waterproofing with traditional coating. Will Tyvek hold back water when placed next to a basement foundation? — Preceding unsigned comment added by 64.250.202.200 (talk) 03:36, 8 December 2008‎

Recycling
Since Tyvek is made of HDPE, and it is branded with the Resin identification code #2, then shouldn't the recycling section of the article also mention that it is easily recycled wherever #2 materials are accepted? --TheJalAbides 18:13, 12 June 2007 (UTC)
 * I created a separate section for Recycling. Although marked with the #2 recycling symbol, I cannot find a single municipal recycling program that will accept Tyvek with #2 HDPE bottles. If you find any, please correct this section as necessary. But for now I added the link to DuPont's Tyvek recycling programs. Sjb0926 (talk) 19:51, 27 June 2008 (UTC)

Class A?
The article says Tyvek has "Class A flammability rating" - but the flammability article that links to doesn't describe what "class a" means (it only has class 0, class 1, etc.). So, without explanation or context, this doesn't tell us anything useful - it doesn't tell us if Tyvek is highly flammable, or the opposite. I'm guessing this is the classification scheme described in the flame spread article? If so, we should link that specifically, with an inline reference to support that classification. -- Finlay McWalter··–·Talk 13:08, 16 June 2016 (UTC)

Dielectric bonding ?
The section: "Scientific characteristics and properties - Adhesion and bonding" says, "Dielectric bonding can be effective in some circumstances ...", but there is no link to a description of Dielectric bonding, and there is no Wikipedia page on the subject. (The WP "Dielectric" page has nothing.)

Please would someone knowledgeable add this information, or a link to it ? Darkman101 (talk) 13:55, 7 June 2021 (UTC)
