Smart Nanotechnologies introduces POLYDEF, a line of polymer additives with fungicidal and bactericidal properties. POLYDEF uses silver nanoparticles with proven antimicrobial capabilities, offering long-term microbiological protection with an impressive 99.99% efficacy rate. It surpasses traditional biocides in stability under extreme temperatures and humidity, ensuring effectiveness across diverse applications. Moreover, POLYDEF is environmentally friendly, maintaining polymer properties without causing degradation.

Silver Nanoparticles in Action

Silver nanoparticles disrupt microorganisms’ metabolic processes by blocking essential protein production. Moreover, this biocidal effect works efficiently in the recommended dosage. Laboratory studies confirm a significant reduction in microorganisms on treated surfaces, demonstrating its efficacy.

Versatility Across Multiple Industries

POLYDEF additives are compatible with various thermoplastics, including LDPE, HDPE, PP, ABS, EVA, PET, and PMMA. Their versatility makes them valuable in many industries:

  • Medicine: Reduces hospital infections and enhances safety.
  • Sports: Improve hygiene on high-contact surfaces.
  • Automotive and Aviation: Enhances cabin and vehicle hygiene.
  • Education: Ensures safer environments in schools.

POLYDEF also finds use in innovative products like 3D printing filaments and self-leveling epoxy floor resins. It’s adaptability extends to flexible, rigid, and viscoelastic polyurethanes. These broad applications and bactericidal properties make it a preferred choice for industries prioritizing hygiene and material performance.

In summary, technologies like POLYDEF address bactericidal resistance by offering innovative solutions. They help maintain pathogen-free surfaces across industrial and everyday settings.
