Its primary purposes are as an insulator (such as for rocket fuels) and acoustic damper. NASA engineered the product to have relatively low outgassing (a problem in vacuum and aboard spacecraft), desirable thermal and acoustic performance, as well as uniformity during distribution and application.
This product is designed primarily for insulation (like in rocket fuels) and sound absorption (as an acoustic damper). It was developed by NASA with the goal of minimizing outgassing, ensuring optimal thermal and acoustic performance, and achieving uniform application.
