Applied Aerospace & Defense’s Novastrat® material can be tailored to a specific CTE to fit the required application. Resins for custom castings as well as films can be provided. We offer two standard versions but can customize as required. Inquire about a custom Low & Zero CTE-matched Novastrat® product today.
Novastrat® 800 is a high-temperature polyimide film with a low coefficient of thermal expansion (CTE), ~4 ppm/°C from -140°C – +225°C, that closely matches the CTE of many metals and metal oxides.
Novastrat® 800 has been successfully used in applications requiring the stability of low CTE from cryogenic conditions (less than -150°C, -238°F) to very high temperatures (greater than 250°C, 482°F). Novastrat® 800 is a recommended grade for applications that require low CTE and stable properties across a wide range of operating temperatures.
Novastrat® 800 is provided as a film in sheet form or liquid resin for spray or flow casting operations. As a liquid, it bonds well to metals and metal oxides, and can be supplied with internal adhesion promoters.
Novastrat® 905 is a high-temperature polyimide film with an essentially zero coefficient of thermal expansion (CTE).
Novastrat® 905 has been successfully used in demanding optical and satellite applications that are exposed to severe temperature fluctuations. Novastrat® 905 is the recommended grade for applications that require essentially zero CTE and stable properties across a wide range of operating temperatures. Novastrat® 905 is provided as a film in sheet form, or liquid resin for spray or flow casting operations. As a liquid, it bonds well to metals and metal oxides, and is supplied with and without a variety of internal adhesion promoters.
