The flowability of polymers cannot be predicted because it is "non-linear." This is also why the melt index (MI), which should be an indicator of flowability, often does not match the actual moldability. The more complex flow known as elongational viscosity is particularly difficult to predict accurately, and the only way to obtain reliable data is to measure it in the same range as the actual molding speed. Imatec provides highly reproducible viscosity data thanks to 20 years of experience and the latest control technology.
