Tolsa offers three different mineral biocide products for thermoplastic applications under the ADINS® Protection name, two based on silver and one based on zinc.
Offers High Antimicrobial Activity
The company’s
ADINS® technology enables the incorporation of different active substances on natural magnesium silicate. This allows optimal distribution of the active substance in the matrix in which it is incorporated, which Tolsa claims results in high antimicrobial activity.
It also improves the thermal and chemical stability of the active substance, helping to minimize the amount necessary for any given level of protection. Target applications include automation, plastics toys, swimming pools, external furniture, and architectural and hospital products.
Tolsa recently carried out a study, in collaboration with Spanish masterbatch specialist Delta Tecnic of antimicrobial activity in
PVC formulations for swimming pools incorporating ADINS® Protection products.
Complying with European Standards
ADINS® Protection is also said to be active against all enveloped viruses, including Coronavirus types, Norovirus, Rotavirus and Adenovirus, according to European Standard 14476:2013+A2:2019. The products also comply with the European Directive on toy safety (2009/48/EC).
“
Once it was verified that the resulting PVC was biocidal against two of the most common bacteria in swimming pools (E.coli and P.aureuginosa), it was decided to carry out an aging treatment in a Suntest XXL+, which simulates half (3,000h) and all (5,000h) of the material lifetime,” said Dr Marta Sacristán, project leader Biocides. “
After this aging treatment, the antimicrobial activity versus the same bacteria remained practically unchanged.”
“
We have some customers who are in the final process of homologating the final formulation with ADINS® Protection for toys,” added Sacristán.
