[edit] History?
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)
I would like to see some history of Tyvek. When was it invented and by whom? What was its original purpose?
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.
Hope that helps
[edit] 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.
[edit] 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)
