Antimicrobial Masterbatch
A. Principle
Silver nanoparticle has excellent activity, and when encountering pathogens, it undergoes an oxidation reaction with bacteria, transforming into silver ions (Ag+) that can directly penetrate and destroy the cell walls. These ions bind to the enzyme proteins that maintain bacterial activity, inhibiting bacterial metabolism and reproduction, leading to the death of the pathogens and achieving antibacterial and bacteriostatic effects. Moreover, after the bacteria die, the silver ions are released from the bacterial body, reverting to nano silver and continuously maintaining their repetitive antibacterial function.
B. Product Information

C. Notice：
1. Masterbatch should be stored in dark and cool dry place.
2. Avoid using raw materials containing NO3- or Cl- in the plastic formulation to prevent masterbatch from color-changing.
