Important characteristics of these materials are:
During preliminary tests, based on glass microspheres and experimental oligocyanurate binder, we have obtained samples of spheroplastics with a density of 0.70 g/cm3 and a ultimate compression strength more than 100 MPa, which exceeds the strength of all Russian spheroplastics known to us.
