we are new at using polyflow.
We try to make analysis about PVC, etc...

we have some informations about our material PVC
for example:

zero-rate viscosity
infinite-rate viscosity
rate index
normalised thixotropy

and we have "shear rate-viscosity graphic"

We learned that we had to use Bird-Carreau Law?

Is this right? or Do you have other advice?
Also we are not sure about "system of units" and how to use the informations that I mentioned above.

Could you please help us?
