what is the price for polystyrene for making keyboards?
356243
I think you are referring to ABS Acrylonitrile Butadiene Styrene, not polystyrene.\n\nand its cost is a function of purchase volume, EAU, stocking, lead time, colorants, and other additives

See what they go for on E-Bay.......you might  want to try a old Hammond  (the ones with tone generators). Look in the papers Ive got keyboards for free, If you can haul it away they usually say, you can have  it.

Polystyrene is soluble in acetone. Dip in in nail polish remover.

This question was already asked and answered - much more intelligently than it is here. It is difficult to search the yahoo questions for specific items with no keyword references,\n\nbut---\n\nhere was my answer to the older question...\n\nhope it helps\n\n\n\nMost of the answers already have some merit.( not in this case, since the answers are awful )\nI have a couple of older keyboards that I really like\nthe key action, the placement, and the key sizes.\n(the backspace is two keys wide, The ENTER is two buttons wide and two buttons tall, such as an IBM Selectric, etc.) \n There are about 5 different kinds of keyboard construction.\nThere are also dozens of rare models, and depending on what\nkind it is, you either can take it apart fairly easily,\nor you should not even open the case! One type of IBM board\nhas a coil spring under each key with a rocker arm. The spring is like the one in a ball point pen, and all are loaded, so that if you take the top and bottom halves apart, you end up with hundreds of springs and parts flying all over the room.\n However. 99% of keyboards are not as complicated. Many keyboards have screws on the back. If so you can use a phillips screwdriver (star) and remove them. The top and bottom of the keyboard usually have snaps that generally open from the front first, and hinge on the back. Gently pop the two halves.  If there are no screws then the halves just pop.\nUse a flat screwdriver to pop along the seams. Every couple of inches there will be a snap.\n You will generally see one of 2 basic types today.\nThere will be a green cirucuit board with copper traces on it, covered by a rubber sheet with buttons in it, or you will find each key has a tiny rubber button -- open the keyboard upside down, so the keys and buttons are held\nin place...\nNote that the SPACE bar, the ENTER and other wide keys may have two buttons, and a wire or plastic bar underneath that has an arm on each end to keep the wide key from wobbling from side to side. These vary quite a bit in how they snap in place. You have to figure out how to unsnap them - usually by springing in the two ends which are snapped into\nsliding slots.  As other answers have stated, the key caps just snap off the tops of the switching posts. They can be gently pryed off with a flat screwdriver end as a lever on one side, and lift on the other. There is an exception to every rule though, and you may have to solve a puzzle. Rare boards may have a release clip somewhere that you have to push, pull or slide to remove the keys, but, I do not see them very often.\n You can then gently remove the cord which may be snapped or screwed in place, and sometimes it has a 5 or 6 pin connector which can be removed from the board.\n Then remove the green board.\nIf there is a full rubber sheet with buttons, you can remove it.\n Then you are left with 101 keys. I take them out.\nIf there are individual buttons, you have 101 ( usually a few more) rubber buttons.\n I take the keys and buttons or rubber sheets, and put them\nin a sink of warm water with ordinary dish detergent.\n If the problem is Chocolate milk or Coke, or Beer, I let\nthem soak. You can use a kitchen dish scrub brush.\n I then take out all the parts, and lay them on a dry\ndish towel. All two or three hundred parts.\n Then, I take the green circuit board and gently scrub it \nwith soap and water on both sides, and lay it out. This includes the chips and electronic parts.\n Then, I get an ordinary hair dryer, and dry the circuit board. I hand dry all the tiny keys, and buttons and the\nrubber sheets.\n The top and bottom carrier plastic halves are washed and dried with the hair dryer.\n Assemble upside down - it helps to have another keyboard\nthere to get all the keys in the correct spots quickly.\n If you have an unusual keyboard arrangement, be certain\nto make a diagram before you take it apart.\n\nPART 2\n Most of the procedure is the same for the second type.\n This type has no green circ

Hey buddy  you may take  a  look at this  site which offers  this  kinda  services and explains everything slightly  good:http://www.e1.greatlakes.com/corp/prodserv/jsp/optical_monomers.jsp\n\nThis also:http://industrial-adhesives.globalspec.com/Industrial-Directory/monomer_MSDS_styrene\n\nand  about  acrylic glass:http://en.wikipedia.org/wiki/Polymethyl_methacrylate

Try ebay or craigslist. If that doesn't work, post it in the newspaper where you live and in the online listings, it's usually free. You'll probably get around $250 for a brand new board and bindings, but even that is asking for a lot. You need to just see what you can get for it. Then, proceed with selling it.

there is a company/corporation that handles recycling of styrofoam and that is the (PPRC)  Polysterene Packaging Corp. you can contact them at 526-0899. Actually, I've seen some of their samples. So what are you waiting for....  There's more... some of the recycled styrofoam were exported to other countries..so go for recycling

Look for local printing companies where you should be able to get the best price.  Other than that you would have to search online.  We have smaller ones made for inside car windows in bulk done cheap, but we do a lot of them.  For ones that are not in large bulk we use the local printers.\n\nBelow are a few online options you can research more on.

Buy some, read the label, and call the company for the MSDS.  If there are nonhazardous ingredients, they will not be listed and you will have to get the company to tell you, search the patent literature, or have it tested ($5k-$25k for starters).

What kind of problem are you having?\nIf the keys are sticky, we'll give you cleaning advice.\nIt doesn't look like you've got caps lock on.\nIf you're typing over words you've written before, you've probably hit the insert key, and need to hit it again.\n\nNew keyboards are quite affordable, you should be able to replace it for about $10 in the US.

there are at least fifty different keyboarding books for a technical college and they cost somewhere between 10 to 40 dollars.
