Electron microscope studies of amosite asbestos fibers reveal narrow bands of polysynthetic twinning and triple chains interlayered with the usual double chain structure of the amphiboles; most of the natural asbestos (amosite) fibers have orthorhombic optical properties of several microns
Approx min fiber width: 1500 angstroms (UICC reference samples (Unio Internationale Contra Cancrum))
Binds well with plastics
