PolygieneTM Polymers: Silver ions ( Ag+ ) prove effective against the SARS virus

First Reported by, March 31, 2004

Perstorp, a Swedish manufacturing company based in Italy, manufactures a silver-compound empregnated polymer ( an antiviral and antimicrobial molding compound ) that was successfully tested by the Chinese Centre for Disease Control against SARS. Perstorp first developed PolygieneTM in 2000, in an effort to create a surface-use polymer that would be effective in killing bacteria. The silver ion emitting polymer was developed for use with products such as toilet seats, door knobs, and other common contact surfaces.

“We tested the compound against a four-hour, eight- hour, and 24-hour exposure period and found no surviving SARS virus upon 24 hours of exposure to the polymer...”
Zhang Panhe, professor at the Chinese Academy of Military Medical Sciences

"The new technology...can be used in a variety of injection-molded amino compounds such as Aminel® and AmitecTM resins, as well as compression-molded aminos...The additive is homogeneously distributed throughout the molded part and is locked into the resin matrix, so it provides protection for the lifetime of the part and never wears off, unlike surface treatments."
