elastomerovou
Elastomerovou is the instrumental singular feminine form of the Czech adjective elastomerový. The base noun elastomer denotes a rubberlike polymer with elastic properties; the adjective elastomerový means “elastomeric” or “relating to elastomer.” In Czech, adjectives in feminine singular take different endings according to case; elastomerovou corresponds to the instrumental case, used when the modified feminine noun is in instrumental. Therefore elastomerovou describes something made of or characterized by elastomer when the noun is in instrumental position.
In practice, elastomerovou appears primarily in technical language, such as polymer science, materials engineering, and manufacturing.
