Doing sounddeadening tests... need EVERYONES help

This is origionlly posted at CAF, but I thought I would post it here as well. There has been good response so far. Thanks for lookin!


Ok here is the deal. Ive read so many "what is the best sounddeadener?" threads recently its making my head loopy. Now being that I work in an R&D lab as a chem engineer, and do sounddeadener testing all the time.... I deided to put this to good use. I want to do a cumulative test on any sounddeadeners I can get my hands on. The problem is it gets expensive buying a whole roll of multiple deadeners when I need less than a square foot of each. Here is where you guys come in. I need any sound deadener you guys can spare. I dont care if it is little pieces of scrap. I would be willing to pay anyone who is willing to give up a square foot $2 for it. But any contributions(no matter how small, a 6cmx6cm piece would even be helpful) would be extremely helpful.

I plan to write a full digression on the results, and post my essay here. I plan to test:
Heat resistance
Cold resistance
Solids retention(VOC's)
NVH testing(Nominal Vibration Harshness)
Sound Absorbtion
Sound reflection
Density
Adhesion
Flexability
Scent


And there are a couple more if I get time. For the adhesion tests, I plan to test in multiple positions(upsidedown, vertical ect), at different temperatures, and I even hope to do some high humidity adhesion tests. For the VOC's I will do a basic test for VOC's, but without their formulation, I cannot differentiate between VOCs that are harmful and those that are not(I can however detect some harmful ones without the formula). I plan on doing tests with both heat gun applied and non heat gun applied materials.



So thats it. Anyone with any brand of aftermarket sounddeadners or even the roofing products that seem to be so popular, I would appreciate even a small sqare(Ill even pay shipping if you want me too). I can only do as many tests as material I recieve, but I should be able to accomplish all of the above tasks with under a square foot.

I already have second skin, and OEM constrained layer(this will be our controll) sounddeadeners.


Thanks guys, shoot me a PM if your interested. I hope we can finally decide which are the best and which are the best for the price.

 

thanks man, but I have plenty of stormguard on the way already. Thanks for the help though.

 

I do believe Im set on the edead right now(let me see if everyone who has volunteered stuff actually sends some). Once I get a tally of what has been sent, Ill post what I got so far, and get in contact with some manufacturers and see if I can get some samples of what I still need sent to me.
