Exceeding critical wall shear stress during high-throughput extrusion causes surface melt fracture, inflating scrap rates and destroying cash covenants.
Off-spec melt fracture disputes drive immediate borrowing base reductions by forcing asset-based lenders to reclassify resin inventory to ineligible status.
Surface melt fracture limits in polyolefin profile extrusion are governed by critical wall shear stress thresholds between 0.08 and 0.14 MPa at the die exit.
Quantifying polymer melt shear stress limits protects toll extrusion conversion margins, prevents off-spec scrap accumulation, and maintains inventory borrowing base eligibility.
