Morphology

butyl + rubber

This is a straightforward noun-noun compound where 'butyl' names a chemical group and 'rubber' names the material, so the meaning 'rubber made from butyl' is directly derivable from the constituents. The type-of/compositional pattern is common across languages, so a B1 learner who knows both words can infer the basic meaning (though they may not grasp technical details like polymerization or impermeability).

Etymology

Butyl rubber comes from the chemical name butyl joined to rubber. The butyl part gives the material a nearly 'air-tight' quality, so the name helps you remember it is used where air or gas must not leak, like inner tubes and protective clothing.
