Materials for Aerospace Applications
Entegris' core competencies in material science and manufacturing enable aerospace suppliers to deliver the precision and performance demanded by these applications.
Through the 2008 acquisition of Poco Graphite, Entegris is now the leading manufacturer of graphite and silicon carbide materials and products for use in Aerospace applications. These materials find use in extreme environments, in systems that require both unparalleled precision and high performance.
In the Optics market, Aerospace and Defense prime contractors are employing POCO’s SUPERSiC® family of materials in several areas. In missile defense, our optics substrates are enabling lower-cost seeker systems with higher optical and thermal performance and improved nuclear survivability. Scanning systems used to detect improvised explosive devices employ laser scanning mirrors made from SUPERSiC silicon carbide to enable higher resolution and faster, more accurate data collection. Light weight and high thermal and optical performance give designers of space-based telescopes greater capability to collect light at higher resolution with lower distortion. And piloted and un-piloted military aircraft are being equipped with sensor pods that employ SUPERSiC optics to enable high-resolution threat detection and tracking. The flexibility of POCO’s SUPERSiC Silicon Carbide Material System allows for the efficient manufacture of lightweight, complex geometries that enable deployment of these high-technology systems.

Advanced aircraft engines rely on advanced materials to enable increased performance. Improvements in thermodynamic efficiency that lower specific fuel consumption require higher temperatures, and drive the need for materials that are able to withstand those temperatures. POCO’s JET family of graphite is being used in tribological and structural applications in the core of these next-generation engines. JET replaces polymers, whose properties are less stable over large temperature ranges and whose capabilities are below the standards required in these new systems. Typical applications are stator vane bushings, vane tip bushing, thrust washers, bumpers, and seals operating up to 1200°F.
The wear resistance and corrosion protection provided by Entegris’ specialty coatings product lines enable these materials to be used in many aerospace applications. These super-hard and low friction coatings stop the formation of macro and submicroscopic wear debris, enabling longer life for critical components. In addition, our optical coatings provide a range of capabilities that allow for low-cost polishing to high-precision, environmentally resistant surfaces.

Entegris’ unique foam and high-thermal-conductivity materials are being used to address thermal management challenges in the Aerospace market. High-performance systems in this market are generating increasing heat loads that need to be dissipated into a variety of non-standard environments. Aerospace vendors are applying our highly conductive, anisotropic materials to guide heat away from critical electrical or mechanical systems using either convective or enthalpic cooling. The combination of light weight and high thermal conductivity make our POCOFoam® and HTC® materials ideal for the Aerospace market. Click here for more information on carbon foam.
