I. Characteristics of Water-Based Metalworking Fluids 1. Alkaline pH: 8 - 9.5. Although this is not the most suitable pH for microorganisms, it does not affect their rapid proliferation. 2. Temperature: The low temperature is sufficient to support the growth and reproduction of microorganisms, but not so high as to inhibit their growth. 3. Usually contains a high percentage of water. 4. The components contain sufficient nutrients.

The core principle is to achieve long-lasting antibacterial effects by disrupting the metabolic processes, cell membranes or enzyme systems of microorganisms. They are widely used in fields such as household appliances, packaging, medical products, footwear materials, and daily necessities, balancing hygiene safety and material performance.

PU polyurethane insole antibacterial agent is mainly used to improve the antibacterial performance of polyurethane insole, prevent bacteria from breeding and reproduction on the insole, so as to keep the insole clean and hygienic.
