ABOUT SERVICE LIFE EXTENSION OF POLYMERS

Use weathering tests in SUNTEST to find out how effective your UV stabilizer is

Complete form & get free Application Note

The combined effect of light, heat and water leads to the aging of polymers. These “weathering” effects initially occur at the molecular level. "Service lifetime" is reached when the degradation has accumulated into a level of changes in the desired properties above the pass-fail criterion.

UV stabilizers extend the polymer service life by protecting against photo degradation and delaying the ageing processes. The effectivity of a given stabilization can be determined by performing laboratory weathering tests.

In this brief Application Note you learn about:

  • SUNTEST XXL+ and XLS+ technology
  • Weathering test parameters
  • Benchmark climates, acceleration, correlation
  • Examples for determination of lifetime extension
