Talk:Polyamide-imide

Questions this article raises and doesn't answer, because it's basically repurposed advertising blurb:

*what*, precisely, is the chemical composition of the polymer? We know what it's made of but not what that turns into, which is, frankly, bizarre for a Wikipedia article.
top of the price and performance pyramid for *what*? *Which* exceptional mechanical properties (I'm guessing not 'fastest wearing', 'softest'...)
Are they only produced by one manufacturer (missing the word 'exclusively'), or is this just one manufacturer that produces them ('also known as Torlon when produced by')?
"Polyamide-imides hold, as the name suggests, a positive synergy of properties from both polyamides and polyimides" - no, actually, that's not what the name suggests. It suggests that it's a polymer containing two monomers, since chemical names are by chemical and not by 'thing that is a bit similar'.

While I am not sure about your second and last questions, I am completely sure that the actual chemical composition is propriortory (trade secret) and they are, thus, only manufactured by Solvay Advanced Polymers. Avenzhang (talk) 23:31, 30 January 2013 (UTC) Avenzhang[reply]

According to this article, its Izod Impact Strength is greater than steel. Questionable and misleading. Are we going to see steel beams, cars, bridges, replaced with PAI? I know its hard to interpret Izod tests, but this is absurd. On matweb.com, general purpose Torlon is listed 2.62 ft-lb/in, compared to 144 in this article. I added a table for molded PAI with matweb values, and a link.
