Summary: The growth of bacteria and mold not only leads to a decline in the physical properties and surface color change of products, but also affects the safety and hygiene of the public environment. Plastic products have complex material types and a wide range of applications. Different types of bacteria and mold easily grow in different usage environments. Therefore, the choice of bactericides and fungicides varies depending on the system.

There are many types of mildew-proof and antibacterial agents on the market, and inferior products are readily encountered. So how do you choose a mildew-proof and antibacterial agent?

1. High-efficiency and broad-spectrum bactericidal and mildew-proof efficiency

The growth of bacteria and fungi not only leads to a decline in the physical properties and surface color changes of products, but also affects the safety and hygiene of the public environment. Plastic products have complex material types and a wide range of applications. For different usage environments, the types of bacteria and fungi that are easily bred also differ. Therefore, the choice of bactericidal and mildew-proof agents varies depending on the system. The ideal product should provide perfect protection for the product at a lower addition amount, generally not exceeding 1%.

2. Good thermal stability to meet the high-temperature processing environment of plastics

On the one hand, the bactericidal and mildew-proof additives should have good compatibility with the plastic itself at a lower addition amount and can be uniformly dispersed in the masterbatch; on the other hand, at the processing temperature, the additives will not cause volatilization loss due to poor thermal stability, affecting the actual effect.

Special outdoor products should choose bactericidal and mildew-proof agents with UV resistance and washability.

3. Does not affect the physical properties and color of plastic products

Traditional silver ion series antibacterial agents, because silver ions are prone to redox reactions, resulting in yellowing, browning, and blackening of the product surface. Therefore, Kopin's mildew-proof and antibacterial agent, which has no discoloration problem and is acceptably priced by the market, is deeply favored by customers.

4. Green and environmentally friendly characteristics of antibacterial and mildew-proof agents

In addition to the above basic performance-related requirements, as China's plastic products are exported to all parts of the world, Chinese processing manufacturers are also facing more green and environmental protection requirements.

Whether in the processing process or the end-use environment, the additives in plastic products should be non-toxic/low-toxic, low-volatility, low-sensitizing, and other safety characteristics. Therefore, when choosing the type of antibacterial and mildew-proof agent product, the potential harm to operators and the potential environmental impact after disposal should be considered. Appropriate protective measures for workers should also be suggested, such as the use of goggles and protective clothing.
