BA 904 is a 30 gauge polyimide based product that is aluminized on both surfaces and then coated with a corrosion resistant coating to protect the aluminum. BA 904 offers excellent physical, thermal, and optical properties with low emittance and solar absorptance values. BA 904 is perforated to facilitate the venting of air during the ascent phase of launch. BA 904 is engineered for use in multi-layer insulation (MLI) blanket applications and is particularly suited for broad temperature ranges and complies with the requirements of ASTM D-5213.
