The company tried several TPE grades, hoping to find a material that would eliminate the adhesion problem while providing comparable softness to silicone. The manufacturer worked with Avient to formulate a custom Versaflex™ TPE that featured a low durometer with excellent resistance to adhesion (sticking). Armed with a new specialty TPE solution, the medical manufacturer handled gasket adhesion with a material that outperformed that not only silicone, but also conventional TPEs.

Some of these adhesives contained solvents, and some were solvent-free. Results showed that the type of adhesive used could negatively affect the performance of the anti-fog agent, with solvent-free adhesives having a greater effect. But some anti-fogs performed better than others, no matter the adhesive used.

The company tried several TPE grades, hoping to find a material that would eliminate the adhesion problem while providing comparable softness to silicone. THE SOLUTION Avient formulated a custom Versaflex™ TPE that featured a low durometer with excellent resistance to adhesion (sticking). THE IMPACT Avient’s formulation expertise produced a specialty TPE solution that surpassed not only silicone but also competitive TPEs to solve the gasket adhesion problem for this medical manufacturer.

It requires a pre-mixing step, a long curing phase and an adhesive to bond to the plastic substrate. Ultimately, the company selected a Versaflex™ OM overmolding grade that bonded tightly to the polycarbonate (PC) substrate of the grips without the need for adhesives. Additionally, compared to silicone rubber, the TPE is easier and faster to process, as it requires no pre-mixing, curing or adhesives.
