Mechanical properties of polymer yarns and
filaments explained
With the Instron 5564 tensile tester we’re able to test the mechanical properties of yarns and cords according to ASTM D-885 and BISFA 2004 ch 7 or on customer defined specifications. All measurements are standard done at 5 specimen (n=5) and average values are reported. Next to standard stress-strain measurements we offer time to failure measurements and hysteresis measurements at room temperature or elevated temperatures.
| Description | Specifications |
| Pneumatic yarn/cord grip | Max load: 2400N |
| Cord Capstan grip | Max load 2.5 kN |
| Environmental Chamber | Operating temperature 50°C – 150 °C |
| Loadcells | 10 N, 100 N, 1 kN, 2 kN and 10 kN |
