Alumina-Silica
Insulation Type ECO-1200A & ECO-1200B
GENERAL INFORMATION
| ZIRCAR Ceramics Alumina-Silica Insulation Types ECO-1200A & ECO-1200B are utility grades of ceramic fiber insulation board suitable for use to 1260°C (2300°C). Both are strong, rigid refractory structures of high temperature ceramic fibers and high purity inorganic binders. ECO-1200A contains a few percent organic binder and aids in room temperature handle-ability while ECO-1200B which is organic free. They offer low thermal conductivity, excellent thermal shock resistance and are an effective thermal insulator in numerous thermal process systems. |

Standard boards are available for immediate shipment from stock. Standard tolerances for boards are +/- 1/4in. on length and width and +/- 1/8in. on thickness.
Boards are typically produced 24in. wide x 36in. long x 1in. to 6in. thick. Custom boards and shapes smaller than a few cubic inches and larger than several cubic feet have been manufactured.
Cylinders typically produced have 1in. to 12in.ID, ½in. to 2in. wall thickness and are up to 20in. long. Custom cylinders and shapes smaller than a few cubic inches, larger than several cubic feet, weighing up to 50 pounds, with ID’s of ¼in. to 24in., wall thickness of 1/8in.’ to 3in. and lengths to 48in. have been manufactured.
Custom boards, cylinders, shapes and preparations are available on request. Our forming processes, large inventory of custom tooling and state of the art machining techniques allow a wide variety of sizes and shapes to be made. Special geometries such as disks, rings, custom bore (round corner square, hexagonal, oval, etc.) cylinders, staved cylinders, troughs, channel, angle, custom-machined shapes and others can be fabricated. Custom machining, compositional variations and the application of surface rigidizers and hardening agents are available.
Please contact us with your special requirements. We are pleased to contact you if you would like more information or want to discuss custom product availability and pricing.
