Substance Description |
Calcium-aluminium-silicate fibres with random orientation with the following composition (% given by weight): SiO2 55,0-60,0 %, Al2O3 4,0-7,0 %, B2O3 8,0-11,0 %, ZrO2 0,0-4,0 %, Na2O 9,5-13,5 %, K2O 0,0-4,0 %, CaO 1,0-5,0 %, MgO 0,0-2,0 %, Fe2O3 < 0,2 %, ZnO 2,0-5,0 %, BaO 3,0-6,0 %, F2 < 1,0 %. Process: typically produced by flame attenuation and rotary process. (Additional individual elements may be present at low levels the process list does not preclude innovation).
