An interesting article worth reading points out that the actual material in the BBBMax product is undisclosed, even in the MSDS sheets (how that is allowable I am not sure).

http://chairsoft-press.com/articles/...ical-analysis/

BioVAL previous biodegradable BBs have a disclosed recipe and that is confirmed by the MSDS sheet, however, the new BBBMax BB is an entirely different material and has its own sheet.

Old Formula: http://www.biovalbbb.eu/uploads/pdf/BBB%20MSDS%20AA.pdf

New MAXBBB Formula: http://www.biovalbbb.eu/uploads/pdf/...0MSDS%20AA.pdf

The article does some comparisions by reverse engineering the weight and size to get a specific gravity and therefore a short list of substances that the product could be made of. Basically in the absence of any other information from BioVAL, it looks like the closest chemical description for this substance is (drum roll please) GLASS.

Here is a clip from that article:

Conclusion

So if BBBMAX aren’t plastic or biodegradable, then what are they made of? What material

* Shatters on impact,
* Has a melting point of 500° to 1800° centigrade,
* Has a density of about 2.4 g/cm^3,
* Is not flammable,
* Can be dissolved by strong acids and bases,
* Is made of natural ingredients and is non-toxic,
* and finally, is transparent?

The only material that comes to mind that has all these properties yet is cheap enough to be a candidate for disposable BBs is glass. For comparison, here is a material safety data sheet for a type of optical glass (meaning transparent) with a density and melting point that closely match those of the BBBMAX. The BK-7 optical glass from that MSDS has a melting point of 532° C while the Bioval claims the BBBMAX has a melting point of 500° C or above and the BK-7 has a specific gravity of 2.39g/cm3 while the BBBMAX has a specific gravity of approximately 2.4g/cm3.

Remember where Bioval claimed on their FAQ that the BBBMAX is not glass? This is now a little hard to believe. If a material behaves like, melts like, dissolves like, weighs like, and looks like glass; one would tend to believe that it was glass. If they are in fact, some form of glass, does this not conflict with Bioval’s statement on their safety page that the BBBMAX meets the MILPOL requirement of biodegradability?
