POLYDEF - Bactericidal additive for polymers

Polymer masterbatch containing silver nanoparticles, endowing ready plastic products with fungicidal and bactericidal properties.

Product description:
  • ensures long-term microbiological protection and increases the safety and attractiveness of the product,
  • microbiological efficacy at the level of 99.99% (even at low concentrations, studies conducted according to international standard ISO 22196: “Plastics. – Measurement of antibacterial activity on the surface of plastics”.),
  • no deterioration of polymers’ physical properties,
  • greater product stability at high temperatures and high moisture in comparison to traditionally applied biocidal agents,
  • low migration of nanosilver,
  • low price,
  • easy application and no need to modify the process line.
