A strong bond: Overmolding TPEs on polycarbonates for medical wearables
Combining medical-grade materials for durable devices
Putting adhesion and chemical resistance to the test
Polycarbonates and thermoplastic elastomers offer a unique combination of rigid and soft materials for housings and interfaces in medical wearables. To create durable devices that can withstand repeated use, there must be a strong adhesion between these materials. Teaming up with Teknor Apex to examine combinations important to wearable devices was a valuable opportunity and experience, and also provided much-needed technical data for our customers.
- Chemical resistance Medalist® MD-36975 and Makrolon® 2458 withstand suntan lotion and isopropyl alcohol.
- Strong adhesion Overmolded polycarbonates show strong adhesion to various TPE grades.
- Biocompatibility Medical-grade polycarbonates meet criteria for skin contact biocompatibility.
