Due to the recent outbreak of COVID-19, there is increased interest for disinfection and sterilization devices. Portable
UV sterilization devices equipped with UVC LED are made to be light and small, offering sterilization on the go, making
it a popular option for everyday use.
USI Corporation’s ViviOn™ is a medical grade polymer, with high UVC transmission and UVC durability properties. For
parts made with ViviOn™ (thickness 1mm), transmission can reach 79 – 88% in the wavelength range of 265 to 280nm. This
is an attractive property for home appliance manufacturers, as ViviOn™ can be made into light covers, shielding and
disposable devices. Currently there are commercial products such as the portable sterilization boxes from the companies
Sandra and Moshi, and the stylus from the company Adonit with sterilization capability.
USI Corporation is founded in 1965, with over 50 years of experience in developing and manufacturing polymers of high
quality. Over the recent years, USI Corporation made rigorous efforts to develop high value-added polymer materials,
introducing a novel Cyclic Block Copolymers (CBC) - ViviOn™ in 2018, a medical and food contact grade polymer with high
UVC transmission properties. Continuing the efforts, USI Corporation is committed to making ViviOn™ the most suitable
material for UVC sterilization applications. In 2020, ViviOn™ also received the Inno Award, an event organized by the
Institute for Biotechnology and Medicine Industry (IBMI), Taiwan.
ViviOn™ is a material with higher UVC transmission and UVC durability than other polymer materials, making it more
effective when made into a portable UVC LED sterilization device. It is also less prone to yellowing after long term
exposure to sunlight. ViviOn™ resins can be processed just like all other thermoplastics, it can be injection molded or
extrusion molded into UVC LED light covers, shielding or disposable devices with design flexibility. When ViviOn™ is
used as a replacement material to Quartz, the weight of the product can be decreased, and the product will be resistant
to breakage, increasing product safety.
