KRAIBURG TPE push the right buttons in the design of medical devices

Buttons are essential in medical devices: they act as interfaces for healthcare professionals, patients, and carers to control the device, input commands, alter settings, and trigger specified activities, as well as provide a tactile and intuitive way to operate the device's essential functions. 

Buttons are also intended to promote user safety while also being accessible and simple to use. Every aspect of a button design, including size, form, and ergonomics, is carefully considered to ensure their visibility and accessibility to the user, while taking physical ability and intended usage into mind.

The thermoplastic elastomers (TPEs), meet functional and aesthetic criteria in medical device buttons, such as soft-touch, color, durability, good haptics, safety, and others.
