I have never heard of these poly plates. Guess I haven't been keeping up on things for a while. What is the feeling on these for a home defense carrier? I keep a Level III vest with SAPI plates near my bed. I have had a titanium plate put in my neck and truthfully the carrier is pretty unbearable. These sound like they may be the ticket. Any thoughts from those with experience on these? Any reasonable sources?

They can be rather expensive. The guy who sent me this plate for testing sells surplus armor. I don't know if I'm allowed to post his contact info.
Don't forget about the yaw issues associated with 5.56 mm ball round impact at closer ranges, as this can greatly effect not only initial upset depth in tissue, but armor penetration ability.
Facts matter...Feelings Can Lie
God, the question has the same answer for any material--if it is thick enough.
Now, if they mold Kevlar(r) fabric into the PE plate...
>Kevlar (aramid) is UHMWPE, isn't it?
NO, polyethylene is really long chain paraffin wax, for all intents and purposes. It is just [R3C-CH2-CH2-CH2]n, where R3 could be simply a carboxyl group.
Kevalr is formed by reacting p-phenylenediamine (NH2-C6H4-NH2) with terephthaloyl chloride (ClO-C6H4-OCl), where the C6H4 is a benzene ring with the reactive "bits" on opposite sides (para position). This makes for a high-temperature resistant aromatic polyamide fiber of formula [-CO-C6H4-CO-NH-C6H4-NH-]n.
Spectra UHMWPE fibers are used for some composites and fishing lines.
