Material Flow Behavior     

GLS overmolding formulations have relatively low viscosity characteristics. They are shear responsive and their viscosity is reduced when they are processed at high shear rates. This helps them flow into thin-walled sections commonly encountered in overmolding. The figure below illustrates the effect of shear rate on the viscosity of GLS overmolding TPEs. For the viscosity of a specific grade, refer to the individual Product Technical Datasheet.
