Finnish innovation PREXELENT™ kills the coronavirus within five minutes from plastic surface

PREXELENT™ | January 26, 2021

According to recent research, Prexelent technology, developed by Finnish Premix Oy, kills 99.7% of coronaviruses from plastic surfaces within five minutes.

A large variety of applications

The technology has huge application possibilities: in restaurants, hotels, public transport, and shops, people move about and touch surfaces that may be contaminated with the COVID-19 virus and transmit it for a long time. By covering the surfaces with an adhesive plastic film containing PREXELENT™, the spread of coronavirus infections can be mitigated.

"Companies are now extremely interested in protecting their own employees as well as customers from the coronavirus. Because Prexelent is a patented innovation, we expect to see great interest in cooperation with us and further development of products,"

Hanna Ristola, CEO of Premix Oy

Proof of destroying the coronavirus

The University of Jyväskylä, Finland, studied the lifespan of viruses on surfaces containing Prexelent; the results show that 99.7% of the viruses died within five minutes. The university did laboratory tests to examine Prexelent's performance in November 2020.

"The research shows that the coronaviruses are destroyed on Prexelent-carrying surfaces almost totally in five minutes. When we take into account the current level of hand hygiene in estimates of the coronavirus's infectiousness on surfaces, the possibility of contact infection from Prexelent-containing plastic surfaces falls very low,"

The active agent is released from plastic at a controlled rate

In Premix Oy's innovation, the virus-killing active agent is mixed with the plastic, and it migrates at a controlled rate to the material's surface for the desired time. The active agent is derived from rosin; it is processed from pine oil that is a by-product of pulp production.

Prexelent-carrying plastic destroys other microbes, too. Prexelent is non-toxic and safe for people and nature, and it does not diminish the recyclability of the end product. For companies in the plastics industry, it is possible to produce Prexelent products like adhesive films relatively quickly.

"Materials containing Prexelent are compatible with widely used machinery and production processes, so the investment required are quite reasonable and possible applications almost limitless."
