Abstract
Extrudability of 20% (vol.) BaSO4 filled medical-grade (additive free) thermoplastic polyurethanes was investigated. Filled TPU exhibits decreased shear viscosity and elasticity in comparison to unfilled TPU, generating reduced pressure drop at the die and reduced pressurization in the extruder. The moisture remaining in the BaSO4 may hydrolyze the polymer. However, hydrolysis is not sufficient and air, entrained with the filler into the extruder, reduces the viscosity and elasticity of the compounded TPU.
