A leading North American medical contact manufacturer faced a challenge when molding the gasket for a contact lens container.  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.

To help customers manage their risk potential, dedicated facilities and systems govern the production of our medical colorants and performance masterbatches. Declarations based on pre-testing of the ingredients we use to standards typically required for medical and diagnostic devices (biological evaluations ISO10993, USP , for class VI devices); and for pharmaceutical packaging and drug-contacting materials (biological evaluation USP, EP chapter and requirements USP and ICHQ3D extractable metals).

APPLICATION BULLETIN Resilience™ HC for Medical Device Housings Offering Improved Resistance to Hospital Disinfectants EFFECT ON POLYMER HOUSINGS FOR MEDICAL DEVICES Unfortunately, the increased disinfection practices among healthcare providers have another effect. Rigid polymers typically used to make housings for medical devices are failing to resist these chemicals. These medical devices could benefit from the excellent chemical resistance found with Resilience™ HC Rigid Molding Materials
