Irgaguard B 5120 Ciba Biocides >> Algicide & Fungicide Biocides >> Biocide, Film protection IRGAGUARD B 5120 is a LDPE masterbatch containing 20% IRGAGUARD B 5000 as active ingredient. IRGAGUARD B 5000 is an inorganic Silver Zeolite based antimicrobial inhibiting the growth of Gram–positive, Gram-negative bacteria, mold and yeast. The product can be processed at temperatures >500OC. Zeolites are crystalline Aluminosilicates with fully cross-linked open framework structures. The framework has a negative charge, which is balanced by cations such as Sodium, Silver, etc. These cations are mobile and exchangeable by e.g. H+/H2O. Special Zeolite design allow for controlled Silver-ion release. The bioavailability of silver-ions is critical to the antimicrobial efficacy. IRGAGUARD B 5120 has been optimized for Polyolefins such as PP (homo, copo), HDPE, LDPE and LLDPE. Key areas of applications are injection & roto-molding applications, film applications, air conditioning, sanitary accessories (i.e. tooth brushes, toilet seats), appliances, hospital supplies and others. IRGAGUARD B 5120 prevents growth of bacteria, mold and yeast on plastic surfaces. Therefore it provides odor control, hygiene maintenance and the possibility for product differentiation. The combination of low migration rates and high melting point makes it especially suitable for high processing and use temperatures as well as for thin layers. It gives durable efficacy even with thin plastic articles. IRGAGUARD B 5120 has been optimized with respect to color retention under sun light exposure as compared to standard Silver-based antimicrobials, which can show discoloration. The pellet form combines low dust content with excellent fluidity. These pellets are highly resistant to attrition; offer a narrow particle size distribution and good industrial hygiene.
