International. A melamine resin foam that works as an acoustic absorbent for air filtration systems, called Basotect, has been developed by the chemical company BASF.
Thanks to its excellent sound absorption properties, its resistance to ultraviolet light and fire, as well as its multiple design possibilities, Basotect is used in several versions of air filters, both indoors and outdoors as a color cover.
Noise reduction
The air in the room is sucked in by the UVC airtube filters and exposed to shortwave UV-C light in an armored stainless steel cylinder. Because the radiant energy in this wave band has a germicidal effect, viruses, bacteria, mites, and mold spores die quickly. At the same time, air filters are very quiet, so that the technical standards of the workplace can be met and noise emissions that have a negative impact on teamwork are avoided.
BASF's Basotect® plays a key role in this thanks to its excellent noise reduction properties: solutions covered with this acoustic absorbent can generate a noise level of max. 38 decibels (measured at a distance of one metre when operating at full capacity). In comparison, conventional vacuum cleaners or kettles produce around 70 decibels.
This BASF solution works on the products of a German air quality specialist. "Our air filters can be used wherever people gather, the recommended minimum distance cannot be met or a mask is sometimes an obstacle," said Hartmut Weinreich, head of technology at UVCclean. "They considerably decrease the risk of infection: scientific studies have shown a high level of efficacy in reducing dangerous microorganisms such as coronaviruses when UV-C technology is used in accordance with the manufacturer's recommendations. The devices are also quiet, highly efficient and safe, and this also thanks to Basotect®, which has convinced us with its excellent sound absorption, flame retardation and the many design options it offers."
Basotect® G+ for industrial and construction applications
Basotect's® inherently flame retardant melamine resin foam is easy to process and mold: it is lightweight, flexible and dimensionally stable at the same time, and shows excellent color stability and a high level of light reflection.
In other airtubeUVC models, UVCclean uses the light grey Basotect® G+ in different forms within the filters, where it makes a key contribution to both the filtration effect and noise absorption. Basotect® G+ is less susceptible to dirt thanks to its color, making it the ideal choice for industrial and construction applications. "Until now, many air filter manufacturers have been using conventional foams to optimize acoustics," said Dietmar Wingerath of Basotect's® European sales team. "By using Basotect®, air tubes set new standards in terms of safety, hygiene and noise protection. Air filters are another example of how versatile our melamine resin foam is: it can be adapted to innovative solutions and, in doing so, helps companies from different industries address the challenges we face as a society."
