Hello;
I have to do some analysis and I've never done before and I need some tips. can you tell me what is tan delta influence on die swell and brenching. And what conclusion may I draw from the following test for EPDM.
The temperature and frequency remain constant while the instrument tests the sample at each of the entered strains. The strain can be from 0.05 to 90 degrees of arc. The strain is limited at higher frequencies.
data example as follow:
Set Angle [%] tan delta
7,00 1,300634737
50,00 1,63936025
99,99 1,923066755
299,99 2,763848593
499,99 3,506078396
1000,00 5,476707976
Can I calculate S' from these data?
thanks in advance
