In this study, a variety of plastic substrates (30 unique polymer compounds), including poly(acrylonitrile-co-butadiene-co-styrene), poly(butylene terephthalate), poly(etherimide), various thermoplastic elastomers (TPEs), poly(carbonates), and poly(amides), were screened for susceptibility to microbial attack using American Society for Testing and Materials (ASTM) G21 (fungi susceptibility), Japanese Industrial Standard (JIS) Z2801, and modified ASTM E1428-15a (bacterial suscep- tibility) test standards. Control samples (top row) are shown for comparison to samples post-incubation and washing (bottom row) TABLE 1 Summary of ASTM G21 results for initial susceptibility screening of untreated resins/compounds Fungal growth Resin/compound 4 = Heavy growth (61%– 100% coverage, fail) TPE, 6 formulations 3 = Moderate growth (31%–60% coverage, fail) Poly(urethane), 2 formulations 2 = Light growth (11%– 30% coverage, fail) Nylon-6,10, PBT, poly(amide) elastomer, ABS, 3 formulations, reinforced Nylon, 2 formulations 1 = Trace growth (
