ablative
Heat shield material
Ablative describes removal or wearing away.
In grammar, the ablative case marks nouns used to express separation, source, or means—common in Latin but absent from modern English.
In medicine and engineering, ablative refers to processes that remove material: ablative laser therapy, ablative heat shields that burn off to protect spacecraft during reentry.
