Dart test
Variation of the energy vs temperature in dry conditions and at 50% relative humidity.

According to 1S06603-2:
  • SampLe: thickness 5Opm I surface: 1256cm2 (circuLar)
  • HemisphericaL impactor: Diameter 20mm.
  • Speed of the impactor: 3.8mIs.


Energy Variation vs Temperature at low humidity content (HR%)

Dart test transition ductile/brittle

The graph shows the evolution of ductile/brittle limit: Pebax addition increase the range of impact resistance of PA 6. This effect is particularly important at low temperature and humidity content.
