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.
