Dow Corning Corp. said that its TPSiV 4000 and TPSiV 4200 Thermoplastic Elastomers (TPEs) have been tested according to United States Pharmacopeia's General Chapter and ISO 10993-10 guidelines and shown to be non irritating and non sensitizing in skin contact applications.
Dow Corning said the results offer strong independent validation that these materials are an option for use in wearable electronics applications, such as wrist bands for smart watches and fitness trackers, as well as for device accessories such as earbuds.
In vivo testing, performed in accordance with the USP General Chapter , Biological Reactivity protocol, demonstrated that TPSiV 4000 and TPSiV 4200 Elastomers were not cytotoxic, said Dow Corning, and showed no indication of systemic toxicity and did not produce skin irritation.
Additional testing performed under ISO 10993-10 provided further evidence that TPSiV 4000 and TPSiV 4200 Elastomers were not skin sensitizers. These test results offer manufacturers an additional level of confidence in using TPSiV products in prolonged skin contact applications such as the fast-growing market for wearable electronics.
