We need your help to identify, reach out to, contact, and confirm from a supplier that they could make us the following product and in the amounts we are requesting:
Thermoplastic master batch (ABS to start for this project, and then eventually PLA, PMMA, PC, NYLON, and others), with filler (black iron oxide, or similar heavy filler) made of particles 20 microns and smaller. The filler concentration must be so great (30% and higher) than the density of the plastic masterbatch is ideally 3 to 4 times that of water (3 g/cm^3 is okay to start). Because iron oxide is [url removed, login to view]^3 a loading of about 50% by volume would be needed to achieve about 3 gm/cm^3.
Please confirm that the manufacturer could supplier us a sample to the USA (5 kg would be ideal) and then we need pricing for a 100kg sample order, and a 500 kg per month order. The target price per 1000kg should be below the price of even a commodity plastic (such as $500-$1000 per metric ton). We can pay much more for smaller batches.
An example of such a company with a similar product and loading rate is here:(do not contact them as we already have) is here:

BONUS fees ($25 each)
The ideal manufacturer could produce us a variety of small batches only 100 kg each, but can be combined to at least 500kg purchases)
The ideal manufacturer could also extrude the masterbatch in the form of filament rolls.
The ideal manufacturer is located in North America
