Morgan Advanced Materials recently announced the availability of materials for heat shields produced by its Thermal Ceramics business. The materials are used in highly demanding environments in industrial applications, such as aerospace, marine and automotive. Materials for heat shields range from high-temperature ceramic fiber materials to microporous insulation, allowing them to be customized to each unique application. The benefits provided by these high-temperature insulation materials reportedly include exceptional durability, low thermal conductivity, and light weight, all while maintaining high standards of product performance.

 

Min-K® microporous insulation products are frequently specified for flight data recorders in markets from aerospace to rail. This lightweight material reportedly has the lowest thermal conductivity on the market and has been specially designed for this application. Morgan’s low-bio-persistent AES Superwool® fibers or the RCF Kaowool® fiber blankets and papers are often encapsulated in aluminum foil or other alloy and textile cloths and used in automotive applications for thermal management and noise reduction. Industrial applications also use high-temperature insulating Superwool, Kaowool, Cerafiber® or Denka® fiber blankets as heat shields in iron and steel, power generation and petrochemical applications.

 

Heat shields manufactured by Morgan are available as shell, flexible, rigid box, or integrated technology. The heat shields’ core materials range from low bio-persistent Superwool fiber and Denka polycrystalline fiber, to Min-K or WDS® microporous insulation. The physical and thermal properties of these materials are maintained with a custom encapsulation. Morgan’s engineering team works with customers to identify and develop a solution for each heat shield application, with temperature classifications up to 2,500°F.

 

All encapsulation materials used in Morgan’s heat shields are reportedly proven successful as thermal barriers in real-world applications. In industrial applications where access for maintenance may be required, like exhaust manifolds or valve and pipe fittings, flexible and shell technologies offer solutions. The same flexible and shell technologies can also be used for aerospace thrust reverser and automotive catalytic converter applications. The flexible encapsulation solution reportedly provides a lightweight jacket that is easy to fit to intricate shapes and remove as required. Shell technology, comprised of a stainless steel encapsulation heat shield, is slim, easy to fit, and easy to remove, making them appropriate for applications where preventing contact with the encapsulated material is preferred. 

In contrast to the flexibility of the shell and flexible technologies, the rigid box technology, made from 1 mm or 5 mm stainless steel, is reportedly well-suited to extreme conditions requiring a rigid thermal barrier, such as those in marine applications. The rigid box technology heat shield requires no tooling, and has been tested and approved as acceptable for use with jet and hydrocarbon fire. Rigid box products are custom made to match the unique application requirements.
