Scratch visibility: Erichsen delta L and ASTM/ISO assessments of TPO resins Conference Paper uri icon


  • Automotive parts are constantly subjected to harsh environmental abuse but still must meet consumer's aesthetic scrutiny. Surface durability is especially important and scratch resistance has been an area of interest for design experts and polymer engineers. Two significant approaches to measuring this phenomenon have emerged: Erichsen Delta L and ASTM/ISO progressive load test. This paper will compare assessments obtained from the two methodologies.
