KEYWORD S additives, antimicrobial, biological applications of polymers, blends, elastomers, thermoplastics 1 | INTRODUCTION The global consumption of specialty biocides at the manufacturing sales level was approximately 1.7 million metric tons with a value of about $7.5 billion.[1] However, the usage of these additives is quite nominal in plastics ($180 million USD) and other hard surfaces.[2] The SARS- CoV-2 pandemic has brought to the forefront the necessity for customers to protect themselves in the environment in which they live, leading to a greater appreciation for disin- fectant products in professional hygiene settings (airports, hospitals, schools, etc.) as well as home disinfection applica- tions, such as laundry sanitization.
