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
