The global antimicrobial plastics market is forecasted to grow signifi- cantly from 36.9 billion to 59.8 billion USD during 2020– 2025, a compound annual growth rate of 10.1%.[3] Similar to the specialty biocides market, the outbreak of COVID- 19 has undoubtedly increased consumer cognizance of high-touch plastic surfaces (e.g., phone cases, point-of- purchase equipment, shopping carts, etc.). Samples were prepared via extrusion utilizing a Leistritz ZSE 27 mm co-rotating twin-screw extruder (Leistritz Advanced Technologies Corp., Nuremberg, Germany), followed by injection molding of 5 � 600 (12.7 � 15.24 cm) plaques, 0.12500 (3.175 mm) thickness using a Milacron™ Roboshot™ S2000i.1 For antimicro- bial testing, specified test specimens were prepared from the aforementioned plaques.
