A strong bond: Overmolding TPEs on polycarbonates for medical wearables
Thermoplastic elastomers (TPEs) and polycarbonates offer a unique combination of rigid and soft materials for housings and interfaces in wearables. To create durable devices that withstand repeated use, these materials must demonstrate strong adhesion and offer chemical resistance.
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.
