Polymers mechanical properties testing

Mechanical testing and analysis of Polymers and Plastics

Intertek has long-term experience in polymers and plastics testing and offers a broad spectrum of tests to determine the mechanical properties of them by using ISO and ASTM methods, product-specific techniques, in-house or custom made test methods. Mechanical properties can be determined by subjecting materials (plates, sheet, film etc.) to an applied force and determining their behaviour.

     

Examples of methods used for testing mechanical properties of plastics and polymers:
  • ISO 868/DIN 53505 - shore hardness A/D
  • DIN 53519-1 - International Rubber Hardness Degree (IRHD)
  • DIN/ISO 2039-1 - ball indentation hardness
  • ISO 2039-2 & ASTM D785 - Rockwell hardness
  • ISO 180 - IZOD impact strength test
  • ISO 179 - Charpy impact properties test
  • ISO 7765-2 & ISO 6603-2 - Free-falling dart toughness test
  • ISO 527, ISO 37 & ASTM D882 - Tensile testing
  • ASTM F1921 - Hot Tack
  • ASTM F88 - Strength of adhesion, weld strength, weld curve
  • ISO 178 & ASTM D790 - Three point bending test        

 
Test parameters include:

    

  • Graves tear resistance / trouser-tear resistance (ASTM D 1004 & ASTM D 1938/ISO 6383)
  • Impact strenght, tensile and bending strenght
  • Notch tenacity / protrusion puncture resistance ( ASTM D 5748)
  • Blocking and re-blocking resistance (ISO 11502)
  • Peel cling of self-adhesive films (ASTM D 5458)
  • Peel-off strength of adhesive-coated films (for block-bottom bags) (DIN 5543)
  • Elastic recovery percentage / Permanent deformation  / Stress retention (ASTM D 5459)
  • Static and dynamic coefficient of friction (ISO 8295)
  • Welding properties of films
