Product Introduction

Plastic antibacterial agent is a broad-spectrum antimicrobial with inorganic zinc ion complex as the active component. It is mainly used to protect plastic or rubber products from microbial erosion such as bacteria, and provides surface activity to offer antibacterial effects on the product surface.
The plastic antibacterial agent slowly releases zinc ions. Since bacterial surfaces carry a negative charge, the positively charged metal ions are adsorbed onto the bacterial surface, disrupting their electrolyte balance and causing bacterial death due to cell wall damage. Meanwhile, metal ions enter the bacteria and react with cellular enzymes, inhibiting enzyme activity and bacterial reproduction, thereby achieving bactericidal effects.

Product Features
• Broad-spectrum antibacterial, effectively inhibits the growth of Gram-positive and Gram-negative bacteria;
• Inorganic material, heat resistant up to 380°C, stable, long-lasting;
• Good anti-discoloration properties, with controlled release rate of metal ions through special processing technology, preventing discoloration during mixing or over time, and excellent UV resistance;
• Good dispersibility, no agglomeration, easily disperses in various substrates;
• Free of arsenic, tin, and VOCs;
• No bioaccumulation, does not cause persistent environmental pollution;
• High safety, environmentally friendly, suitable for food contact applications; complies with EU environmental regulations.

Product Applications
Plastic antibacterial agent is suitable for plastic or rubber products, such as mother and baby products, daily tableware, antibacterial medical devices, antibacterial silicone rubber keyboards, etc.

Application Information
