介紹 | APYRAL? products have a very high chemical purity of at least 99.5 %. The remaining constituents consist mainly of sodium oxide, which is part of the crystal lattice and partly adhering to the APYRAL? surface in hydrated form, as well as traces of iron and silicon compounds. Aluminium hydroxide is non-soluble in water with amphoteric characteristics. Due to the sodium oxide components, a watery APYRAL? suspension has a pH value of 8-9. This must be taken into consideration in watery or other alkali-sensitive solvents or dispersions - particularly where other additives are used, which are restricted in use to a certain pH range. In case of doubt, tests must be made for possible interactions. In many applications APYRAL? is not only used as flame retardant, but does also fulfil a function as white pigment. Due to its whiteness, APYRAL? behaves neutral to the colouring of polymers. The Mohs hardness of 2.5 - 3 causes no problems even in highly filled molten masses. The relatively high heat capacity cp of 1.65 J/gK at 400°K (127°C) has a beneficial effect on the dimensional stability under heat for APYRAL? filled polymers. This even has priority in some applications. With a specific density of 2.4 g/cm3, APYRAL? is a medium-density mineral filler. As a result of the required filling levels, the density of the flame-retarded plastics is increased compared with the unfilled polymer. In total, however, APYRAL? is one of the most attractive flame retardants, even on the basis of a volume-specific cost balance. |
