Elongation at Break

Elongation at break is the percentage increase in length that a material will achieve before breaking. This figure is shown as a percentage and is usually measured using test method ASTM D412. A higher percentage usually indicates a better quality material when combined with a good Tensile Strength.

Solid Rubber that exhibits a high Elongation at Break but a low Tensile Strength may be indicative of a poorly mixed or under cured polymer, which if used to produce Rubber Gaskets or Seals will see premature failure.
