Symptom: Wear, Premature Failure

Possible Causes: What could cause this problem?


Wrong material or formulation, material failure, extreme use conditions

Sample Testing Plan: How do you measure?


  • 1. Measure directly using single-bounce Diamond, ZnSe or Ge* ATR
  • 2. May require cutting away top surface to expose interior
  • 3. Measure sample and reference part on TGA-IR


*Ge for carbon-filled polymers

Data Analysis Plan: How do you identify the problem?


  • 1. Search libraries to identify material
  • 2. Compare sample data to reference part data to identify differences
  • 3. Change formulation if appropriate
