Definitions
- the invention relates to polymers with an antibacterial and fungicidal bioactive glass as an additive.
- antibacterial and fungicidal activity in polymers can be achieved by introducing aluminum silicates, such as zeolites, see JP-A-3145410; JP-A-1164721, US-A-6071542, JP-A-03145410, US-A-5698212, US-A-5939087, US-A-5827524, EP-A-732052.
- the aluminosilicates contain small amounts of heavy metal ions with an antimicrobial effect, such as Ag, Cu, Zn, Sn Pb, Bi, Fe, Cr.
- the actual antibacterial effect is based on the heavy metal ions introduced, the zeolite only serving as a matrix and having no antibacterial or fungicidal effect.
- Organic, active microbial compounds such as triclosan (trichlorohydydiphenyl ether) or paraben (p-hydroxybenzoate) can also lead to health problems and allergic reactions. In addition, organic compounds are difficult to fix locally.
- organometallic substances e.g. Mercury and / or copper organyls are used, in about 70% of the products the effect is based on arsenic. These substances are questionable because of the toxicological and ecological hazard.
- the object of the present invention is to provide an antibacterial and fungicidal additive for polymers without a harmful side effect.

- the bioactive glass fulfills the requirement of toxicological harmlessness since it contains no heavy metals or organically active compounds.
- the glass composition influences the release of ions.
- an antibiotic effect is achieved, which can be adjusted from biostatic to biocidal depending on the ionic content.
- a possible long-term effect should also be emphasized, since the release of the ions can be controlled by varying the glass composition.
