Set Properties

Set properties of polymeric material can be defined as retention of permanent deformation after removal of load. Load can be either compression or tension. Deformation can be expressed as reduction of original thickness (Compression Set) or increase of original length (Tension Set).

Rubber products like seals and gaskets are subjected to continuous stress condition. Repeated compression of a rubber seal over time results in progressive stress relaxation. We are providing different method to determine set properties of elastomers.

  • Tension Set: ASTM D 412
  • Compression Set: ASTM D 395/ISO 815
  • Stress relaxation Compression mode: ISO 3384
  • Stress relaxation Tension mode: ISO 6914
  • Creep compression mode: ISO 8013
