Broad Spectrum Silicone Antimicrobial Agent, For Baby Silicone Tableware & Medical Silicone Parts
1. Pain Point
Ordinary silicone rubber products such as LSR liquid silicone, platinum cure silicone and RTV silicone are prone to breed Escherichia coli, Staphylococcus aureus and other harmful bacteria after long-term contact and use. Unpleasant odor, hygiene complaints and high return rates are big headaches for silicone manufacturers. Many silicone antibacterial additives on the market easily cause silicone yellowing, poor transparency and decreased mechanical properties. Some antibacterial powder or antibacterial liquid fails to survive high-temperature vulcanization and loses antibacterial activity after molding.
2. Solution
Our silicone antibacterial agent is a silver zinc ion composite silicone antimicrobial additive customized for silicone materials. It disperses evenly in the silicone matrix during mixing. As a food grade silicone antibacterial additive, it delivers broad-spectrum and long-lasting antibacterial performance with low migration and no yellowing. It has excellent heat resistance and good compatibility with LSR liquid silicone, solid silicone, platinum cure silicone and RTV silicone. It can effectively suppress bacterial reproduction and reduce odor risks, helping your finished silicone products pass the ISO 22196 antibacterial test.
