töjbar

Töjbar is a Swedish adjective meaning "stretchable" or "able to be stretched." It is derived from the verb töja ("to stretch") and is used to describe materials, objects and sometimes abstract concepts that can be extended in length or size without immediate failure.

In materials science and engineering, töjbar refers to the capacity of a substance to undergo tensile deformation. Common examples include elastomers, certain textiles, polymers and metals with significant ductility. Quantitative properties related to töjbarhet (stretchability) are measured by tests such as tensile testing, reporting metrics like elongation at break and elastic modulus. The term does not by itself specify whether deformation is elastic (reversible) or plastic (permanent), and is often qualified with words such as elastisk (elastic) or töjbar med plastisk deformation.

In everyday language, töjbar is used for garments (stretch fabrics), seals, cords and medical materials like bandages or implants that require flexibility. It can also be used figuratively to describe rules, schedules or interpretations that are flexible or adaptable.

Grammatical forms include töjbart (neuter) and töjbara (plural). Synonyms in Swedish include stretchbar and böjbar depending on context; antonyms include styv (stiff) and oböjlig (inflexible). The term is common in technical specifications, product descriptions and colloquial speech.
