Why do we need antibacterial, antivirus and antifungal products?
….. to protect us public places, public transport
….. to ensure greater hygiene around work, sport, hobby, home
Demand for antimicrobial products • Medicine and pharmacy (e.g. medical implants, drugs) • Household chemistry, toilet preparation and cosmetics • Pains and varnishes • Food industry • Packaging industry (packages, foils) • Household goods • Interior equipment • Textiles and clothing industry • Paper and wood industry • Toys, playground equipment, sport equipment
Materialssolutions Antimicrobial additives: silver (Ag), gold (Au), copper (Cu), zink oxide (ZnO), titanium dioxide (TiO2) silicon dioxide (SiO2) especially as nanoparticles
Technological possibilities Principal processing methods for plastics: • extrusion • blow moulding • injection moulding Easy application to different polymers egPS, PP, PC, PE, PVC, PBT, AS, PA, ABS, PLA
Antibacterial additives • bacteriostatic- stop bacteria from reproducing • bactericides- kill bacteria
Examples of commercial antibacterial additives masterbatches powders
