Though the viscosity of TPEs are reduced when processed at high shear rates, TPEs must be “packed” into a mold to ensure complete fill-out. The results were impressive: • Better tension set, improved compression and enhanced permeability • Slashed $70,000 from production costs by reducing cycle times and eliminating assembly steps • Lower specific gravity of TPEs trimmed overall part weight, which cut $36,000 in annual freight costs • Reprocessability of TPEs shrank scrap rates, saving more than $70,000 in material waste SWITCH TO TPEs BOOSTS BOTTOM LINE CASE STUDY READ MORE ONLINE For a manufacturer seeking to redesign a liquid injection-molded silicone medical pump valve insert, Avient suggested custom-formulated grades of Dynalloy™ OBC and Versaflex™ TPEs that would deliver better multi-functional performance than the previous design, while also facilitating easier two-shot molding.

Beryllium copper can be used for inserts, slides or cores to increase heat transfer rates and reduce cycle times.

As shown in figure 2, in high shear rate regimes, the viscosity is at the lower end of the spectrum which helps the TPE to flow into and fill the thin-walled sections commonly encountered during overmolding.
