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.
To reduce the incidence of device-associated infections,
antimicrobial technologies have been utilized in a variety
of ways ranging from bulk-imbedded additives to sur-
face grafting techniques.[13,14] In particular, silver-based
additive technologies are frequently explored for
healthcare applications due to their favorable toxicological
profiles and broader regulatory approvals, while silver
nanoparticles with controlled, long-term release profiles
continue to be a very active and promising area of biomedi-
cal research.[15-19] In textile segments such as sports active-
wear, biocides are used to prevent the growth of odor-
causing bacteria from perspiration.[20,21] Additionally,
high-end recreational products such as boats utilize bio-
cides to preserve the aesthetics of PVC products used for
seat covers since bacterial growth may lead to pink staining
caused by specific bacterial metabolites.[22,23] With respect
to the mechanism of action, many antimicrobial products
work by attacking enzymes common to a variety of
microbes, interfering with membrane transport processes
(e.g., importing environmental copper into the cells) as
well as interfering with iron metabolism pathways.[24,25]
Herein, an assortment of both rigid and flexible resins/
compounds will be evaluated for susceptibility to determine
whether particular resin chemistries or compounds are
inherently vulnerable to microbial growth and subsequent
degradation or other deleterious effects.
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.
