Dynamic testing device |
Turnable sample rack stretch frequency: 0.5Hz Sample stretched cyclic between 0 to 10% or other specify stretch ratio Continuous or intermittent dynamic stretching available Sample rack rotating rotates at the specified speed available |
Static test device |
After the sample is stretched by 20% or other specified ratio, it is fixed on the sample holder, and the sample holder is rotated at a specific rate to fully expose it to the specified ozone gas. After reaching the predetermined time Observe whether the surface of the sample is cracked |
Sample rack rotating velocity |
20mm~25mm/s or adjustable at will |
