Here is a comparison of some materials we are looking at.
Solid glass spheres:
Crush strength 30,000psi
Mohs 6
Density 2.5g/cc
Zeeospheres
Crush strength 60,000psi
Mohs 7
Density 2.1g/cc
Granite
compressive strength 19,000 to 29,000psi
Mohs 7
density 2.75g/cc
E/G
compressive strength 18,000psi
Density 2.3g/cc
Is crush strength the same as compressive strength?If so Zeeospheres look good.We are fooling around with different materials and additives.E/G from the manfactures is simply sand and aggregates for vibration damping.Changing the materials or upping the properties will not guarante vibra damp properties.Zeeospheres are looking good.Patent anyone?
Walter did some Zeo only in epoxy.Walter any news?
