List of polymers tested and identifying features. 6© 2021 Avient Corporation, 33587 Walker Road, Avon Lake, Ohio USA 44012 To assess the results of the chemical resistance testing, an ESCR criteria was developed that took into consideration a visual observation as well as the mechanical data. The data in these tables clearly shows that the Trilliant HC8900 and Edgetek ET8900 series outperformed the competitive materials across all different disinfectant/cleaner types. While the method used in this study is useful for providing comparative data, it should be noted that the testing is conducted under a single strain condition with the disinfectant applied in a manner intended to accelerate ESC behavior; the strain and exposure conditions based on actual use scenarios should always be tested to confirm the anticipated performance in the field.

PREPERM™ Solutions for 5G The increased demand for data capacity and low latency and the growing volume of connected devices require more base stations and higher frequencies. The dielectric measurement data up to 220 GHz indicates that the dielectric properties of PREPERM thermoplastics are stable and not dependent on the frequency.
