I know we have smart & attentive people here - what IS this stuff?:

http://www.posterrevolution.com/content.cfm/poster-hangers

I know it's some kind of... something, re-purposed to hang posters - and re-priced at like $1 per foot or more... It's a conduit or something? I have a load of new posters incoming. I have previously used wood lath glued together, dirt-cheap but time-consuming. If I can just find out what this stuff REALLY is, but I'm sure not laying out $50 or something for cut-up lengths of some cheap little bitty plastic stuff. I admire their ingenuity and all, but not with my wallet.
 
Where are you getting $50 from? The most expensive item on that page is $5.80. I would consider that fair and reasonable. Of course, if you are going to be hanging many posters, then you will be buying many sets.
 
Looks suspiciously like the little plastic report binders:

Try looking for "slide binders",  "binder bar", or "snap frame poster"
 
I think they have only been around since the 70's - maybe longer - my memory does not go further back.  :laughing8:
 
True resins are organic, but the term is used extensively in the plastics industry for some synthetic materials. Basically, it's a semi-solid that hardens into a solid relatively quickly. As such, it's easy to make extrusions from, which is what those parts look like. You force it through a shaping die while it's still sorta squishy via heat or chemistry, and it comes out more or less solid.

A lot of fun stuff gets made that way. Many breakfast cereals, for instance, are pushed through dies under such pressure that it creates heat and cooks the grains, and a flying knife separates it on the other side. Aluminum is another one that gets extruded a lot. Kind of a trick, because it has a very narrow temperature range where it's plastic, but that's where you get all the various channelwork that's used to make heatsinks, storm windows and doors, etc.

That maybe partially explains this totally BIZZARO section in our shiny new Walmart SuperStore. I try to avoid it like the plague, but I can't help but drift in once in a while. And there are TWO WHOLE AISLES in the so-called "food" section, with stuff honestly piled up eight feet high - and none of it is "food" as we know it. It's ALL made out of corn, it's all yellowish-reddish pink & brown. And it's all these entertaining (I guess) extruded kinda party shapes, and I'm guaranteeily certain that if you tried to live on it you'd die of starvation while simultaneously pooping big styrofoam. I could eat a certain amount of it if the pay was good enough, but it's actually working the other way - people pay them for the right to take it home! Whoeee.
 
Yeah, the stupor markets love breakfast cereal. It's small, light, cheap and sells for big bucks. Most of that money is in the packaging, advertisement and profit, and your suspicion is correct that you couldn't live on it. I've had numerous occasions to be in the plants that make many of them to deal with their machinery/automation. Battle Creek, MI is "cereal city". Purina, General Mills, Kellogg, etc. all call that place home. You wanna see a panic, let something happen in the process so they're not making shippable product. They go running for the vitamin spray E-Stop like it's a contest, as it's the only thing of value in the plant. Outside of the acres of stainless steel, that is. Fun stuff.
