Polymer Chemistry: Tensile Testing

  • Page ID
  • In a tensile test, a sample of known dimensions (including thickness) is held between two clamps.


    As the sample is stretched, the force exerted by the instrument and the length (and sometimes cross-sectional area) of the sample are measured. This data can be used to construct a stress-strain curve and to calculate several mechanical properties of the polymer.
