Smart wearable devices, especially sports or smart watches, are by default supposed to meet a series of requirements: scratch and abrasion resistance, skin irritation-proof, resistance to daily-used detergents, non-tacky feel, light weight, durable and so on.

Eventually, KRAIBURG TPE and Covestro Makrolon® PC are recommended as the materials for watch strap and case respectively. This material combination does not only fulfill the mentioned requirements, but also provide the design flexibility and process advancement due to the 2K molding possibility. Needless to say, these materials fulfill all the mandatory international laws and regulations.
