TPE Knowledge Base Due to this unique viscosity/shear rate dependency, normal melt index testing (done at shear rates as low as 50 1/sec) will not reflect how the TPE will process at higher shear rates. Shear rates during extrusion processing are usually in the hundreds of reciprocal seconds and shear rates during injection molding may go as high as 11,000 1/sec.
