GLS™ Product Line

There are a variety of GLS™ soft touch TPEs designed to have excellent adhesion to a number of rigid plastic substrates. The table below summarizes the standard grades that are currently available and their corresponding substrates.

If you do not see your substrate in this table, please contact GLS directly; we can develop a custom TPE that is optimized to bond to your specific substrate.

Material Flow Behavior

GLS overmolding TPEs are shear responsive, thus their viscosity is reduced when they are processed at high shear rates. This allows for easy flow into thin-walled sections commonly encountered in over-molding applications. 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.
