CLEVELAND – October 31, 2018 – At MD&M Minneapolis today, PolyOne Corporation announced that Trilliant™ HC material outperforms FR PC/ABS after exposure to harsh disinfectants, according to tensile strength stress tests performed by an independent A2LA-accredited lab. Testing results show that Trilliant HC 2020 retains higher tensile strength than common FR PC/ABS materials after seven-day exposure to typical disinfectants. Developed as a drop-in replacement for FR PC/ABS, this innovative Trilliant HC formulation was recently used successfully by a medical device OEM seeking to improve resistance to cracking and brittleness for its housings.
