High Temperature Ceramic Foam

Manufacturing techniques include impregnating open cell polymer foams internally with ceramic slurry and then firing in a kiln leaving only ceramic material.

High temperature ceramic foam.

Ceramic foam is a tough foam made from ceramics. 2000ºf white hot parts can be immersed in water with out cracking. Standard board grades are standard high purity and zirconia. It is easily cut sawed and drilled.

They experience very little shrinkage at high temperatures but the brittle material can be somewhat difficult to work with. Boards are available in a variety of temperature ratings dimensions and custom vacuum formed shapes. Thermal shock resistant ceramicfiber insulation sheets for furnaces. Designed for fluctuating high temperature applications these semi rigid sheets are typically used in furnaces and fire protection applications.

The boards are manufactured through a wet forming process using alumina silica fibers and binders. 310m ceramic foam is composed of over 99 pure fused silica ceramic and offers low thermal expansion and conductivity high thermal shock resistance and high thermal reflectance. For example the typical heat resistant material made of foam ceramics is heat resistant brick which is made of zro2 sic silicon nitride si3n4 and magnesia material and its use temperature as high as 1600. Ceramic fiber boards provide a rigid solution for ceramic fiber insulation.

Tecfoam tm is a high purity alumina ceramic foam with closed cellular structure low density high strength and excellent thermal shock resistance giving its an important role in high temperature insulation applications. High purity alumina ceramic foam insulation alumina ceramic foam contains more than 99 6 al2o3 with closed cellular structure features its low density high strength and excellent thermal shock resistance giving its an important role in high temperature 1800 insulation applications. Airex c71 is a closed cell cross linked rigid foam with high temperature resistance excellent rigidity and a great stiffness to weight ratio. This is new product is different from other thermal insulation materials in the market.

Ceramic matrix composites cmcs provide high temperature oxidation stability relative to metals and enhanced toughness relative to monolithic ceramics. The foams may consist of several ceramic materials such as aluminium oxide a common high temperature ceramic and gets insulating properties from the many tiny air filled voids within the material. It can be processed with all commonly used resin systems and processes. 3000 f rescor 310m fused silica foam.

It is formaldehyde free and demonstrates excellent long term stability under humid conditions and after temperature cycling.
