NeXolve Novastrat® 905 Polyimide
Categories: Polymer; Film; Thermoset; Polyimide, TS; Polyimide, Thermoset Film

Material Notes: High temperature polyimide film with essentially zero coefficient of thermal expansion.

NeXolve Novastrat® 905 is a high temperature polyimide film with essentially zero coefficient of thermal expansion (CTE). Because of this unique property, Novastrat® 905 has been successfully used in demanding optics, satellite, and industrial 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.
