Tensile strength

The tensile strength of an elastomer is the tensile stress reached at the breaking point of the test piece. By definition the force required is expressed as a force per unit area of the original cross section of the test piece.

The same test also gives a value for the elongation at the breaking point. With a tensile strength of ca 42 MPa and 650% elongation at break, Vulkollan 92 Shore A shows high values.


These high values remain almost constant over the complete hardness range. In normal conditions Vulkollan® is rarely loaded under pure tensile stress, as such these parameters are used to compare materials.
