Solvay and Metrex, which makes surface disinfection products, report that Solvay’s polymers are able to chemically resist strong disinfectants used to combat Covid-19.

In recent tests conducted by the two companies, six Solvay polymers were tested against three Metrex healthcare surface disinfectants, CaviWipes, CaviWipes Bleach and CaviWipes 2.0. The results revealed that Solvay’s Radel polyphenylsulfone (PPSU), Udel polysulfone (PSU), Veradel polyethersulfone (PESU), Ixef polyarylamide (PARA), Kalix polyamide (HPPA) and Amodel polyphthalamide (PPA) polymers all meet performance acceptance criteria for retention of impact strength, tensile strength and color after repeated exposure to Metrex disinfectants. On average, all six Solvay materials exhibited over 90% retention of impact and tensile strength and a Delta E color difference of less than two.

‘As aggressive disinfectants take an increasing toll on traditional plastics, medical device and equipment manufacturers are looking for higher performing plastics that withstand repeated exposure to these chemicals,’ said Jesal Chopra, vice president at Solvay.
