Material Notes:
SKAMOL V-1100 & VIP-12 vermiculite slabs have the following characteristics: Max. service temperature: Up to 1150°C (2102°F)Hot-face applications or back-up insulation of all refractory constructionsExcellent insulating valueHigh mechanical strengthGood thermal shock resistanceCan be used in furnaces with reducing atmospheres due to their high resistance to carbon monoxide and hydrocarbonsSeveral grades available in various combinations of bulk density, insulation properties and compressive strengthA variety of uses in high-temperature kilns and furnaces, combustion plants, boilers as well as in hearth and heating appliancesHigh-density grade VIP-12 has a good resistance to cryolite and fluorides, which makes it particularly suitable for uses within the primary aluminum industry.Information provided by Skamol.
