From a product-type viewpoint, flexible
polyvinyl chloride (PVC) and poly(urethane)-foam-based
applications have used biocides for decades.[8,9] PVC is
especially vulnerable to attack from fungi and bacteria
due to extensive plasticizer usage in flexible applications.[
10] Poly(urethane) foams are another notable consumer
of biocides because of their porous nature, which pro-
vides an ideal environment for microbes to grow.[11,12]
Therefore, it is not surprising that many applications
based on these two materials have significant usage of
biocides; commonly, oxybisphenoxarsine or lower toxic-
ity alternatives such as zinc pyrithione (ZPT) antimicro-
bials are employed.[10] Specific example applications
include kitchen and bath accessories, swimming pool
liners, carpet backing, sleep solutions like mattresses and
pillows, roofing membranes, and tiles.
