Polyethylene Bulletproof Vests Better Than Kevlar

teflonscout writes "When I think of bulletproof vests, the first word that comes to mind is Kevlar. Wired is running a story on Dynema SB61, a bulletproof material that is made of polyethylene. It is a higher grade of the plastic found in Tupperware. The story also mentions the recall of Second Chance bulletproof vests that were made from Zylon, a material that degraded slowly when exposed to moisture. At least one police officer was injured when a bullet penetrated his Zylon vest. Polyethylene is impervious to moisture. The first vests made from this new material are 5mm thick and can stop a 9mm bullet traveling at 1777 feet per second, which is slightly better than other top of the line vests."

Nor do they cleanly invalidate them.

They don't need to cleanly invalidate them. You're implying that invalidation can only come on your terms? Please stop posting if you don't care, you're trolling.

I don't know where in the heck that came from.

From your original post, "Washington Compost".

The rest of your post indicates equal lack of comprehension, both of the issues at hand, and of what I wrote.
