VivaTurf’s antimicrobial non-infill turf systems are developed and tested in accordance with internationally recognized standards, including ISO 22196 (Measurement of antibacterial activity on plastics and other non-porous surfaces), ASTM G21 (Resistance of synthetic polymeric materials to fungi), and GB/T 36432-2021 (Evaluation of antibacterial performance of artificial turf). The system’s key technical parameters demonstrate clear leadership in Western markets.
At the core is a composite antimicrobial formulation combining nano silver ions, zinc ions, and organosilicon quaternary ammonium compounds. These agents are introduced through melt-compounding into both turf fibers and backing materials, enabling full-material antimicrobial coverage rather than localized surface treatment. The antimicrobial additive ratio is precisely controlled between 1.5% and 2.0% (approximately 1.8% in fibers and 1.5% in backing), significantly lower than the industry norm of around 3%, yet achieving superior efficacy. Independent REACH-compliant testing confirms heavy metal migration (silver and zinc) below 0.1 mg/kg, meeting food-contact-level safety requirements, with skin irritation classified as “non-irritating.”
In standardized testing, VivaTurf non-infill turf achieves a 24-hour antibacterial rate of ≥99.99% against E. coli (ATCC 25922) and Staphylococcus aureus (ATCC 6538), far exceeding the ISO 22196 qualification threshold of 90%. Inhibition rates against additional pathogens, including Klebsiella pneumoniae and Pseudomonas aeruginosa, consistently exceed 99.9%, covering eight major categories of common pathogenic microorganisms. Anti-fungal performance reaches ASTM G21 Class 0, the highest rating, with zero visible mold growth after 28 days under 28°C and 95% relative humidity, fully suppressing common fungi such as Aspergillus niger and Aspergillus flavus.
