About Insulating Alumina Castable 35% Al2O3 P-CAST-A35In
Insulating Alumina Castable 35% Al2O3 P-CAST-A35In is an insulating castable based on lightweight fireclay with Min. 35% Al2O3, suitable for service temperatures up to 1200 °C. It has a hydraulic bond and is installed by casting. Material type according to the datasheet: Insulating castable; raw material basis: lightweight fireclay.
Insulating castables have a low bulk density and are used in back-up linings to reduce heat loss; they are not designed for direct contact with molten metal or heavy abrasion.
Technical properties
- Maximum service temperature: 1200 °C
- Al2O3: Min. 35%
- Bulk density: Approx. 1.3 g/cm³
- Grain size: 0 – 5 mm
- Cold crushing strength after drying at 110 °C: 90 – 150 kg/cm²
Installation, packaging and storage
Installation: casting. Water addition, drying and initial heat-up should follow the manufacturer's instructions to achieve the best properties. Packaging: 30 kg bags (dry mix, water is added on site). Shelf life: 6 months (dry, cool, frost-free place).
The values in the specification table are taken from the product datasheet. Contact the Pas Espadana technical team to select the right grade for your operating conditions.
