Talk:Dyneema

Wetting

This is a tough one: in the "Properties" section, my original language said something general about "poor wetting", which I mainly meant to refer to wetting of resin in a composite layup. Unfortunately, this was a very clunky way to get this concept across. A series of cosmetic fixes has led us to the current language, which says "does not get wet easliy". "Get wet" almost universally refers to water, which mostly misses the point. Any ideas on how to fix this?--Joel 02:09, 25 Jun 2005 (UTC)

UHMWPE at last

The big changes recently are due to the advent of a more general article on the material from which these fibers are made. I recommend you check it out!--Joel 30 June 2005 00:35 (UTC)

Olefin?

The polymer material is called an olefin in the article. But, if it is indeed based on polyethylene, it has to be a paraffin [alkane], since polyethylene does not have unsaturated chemical bonds. Nevertheless, having no knowledge of this particular material, I chose to abstain from editing the article right away, waiting instead for an expert to intervene.

Production?

I am concerned with the production section. Olefins are generally highly resistant to solvents, yet the production section says that Dyneema is is drawn into fibers as the solvent evaporates. My guess is that the fibers are drawn as the PE polymerizes. Can anyone find a citation? I will search for something myself as well.

Also, to the anonymous user above questioning the use of "olefin". In terms of organic chemistry, you are correct, but in the plastics industry, it is common to call anything in the PE or PP family an olefin. --Gbutler77 05:59, 11 February 2006 (UTC)
