What is Antibacterial?

a) In our daily life, the antibacterial we talk about is, more accurately is inhibits the growth of bacteria and mold on the surface or inside of an object, thereby achieving a clean and safe use experience, and can also extend the product's life and reduce the consumption of natural resources.

b) So what is the difference between antibacterial and the alcohol or 84 sterilization we often use? There is an essential difference between these two. Antibacterial can provide a lasting inhibitory effect, while the bactericidal product works very quickly, but the duration is short, ranging from a few minutes to a few days depending on the bactericidal substance. For antibacterial products, the inhibitory effect can last from a few months to a few years, and even cover the entire product life cycle.

How does Antibacterial Masterbatch Effectively Inhibit Bacteria and Mold?

The active ingredients contained in antibacterial masterbatch, achieve antibacterial effects by inhibiting the growth of microorganisms, destroying the biological structure of microorganisms, interfering with the metabolism of microorganisms, and affecting the DNA of microorganisms.

What are The Inhibited Bacteria?

The microorganisms we encounter usually include bacteria, fungi, viruses, and microscopic algae. Antibacterial masterbatches have different degrees of effect on them. What we call antibacterial usually refers to the inhibition of bacteria and fungi.

Due to the impact of the epidemic, the inhibitory effect of viruses has gradually received more attention in recent years.

Bacteria can be divided into Gram-negative and Gram-positive bacteria based on biological structure. Representatives of Gram-negative bacteria are Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, etc.

Gram-positive bacteria are usually Staphylococcus aureus, Clostridium tetani, etc. These can be effectively inhibited by antibacterial masterbatch.

Among fungi, antibacterial products are more focused on the range of molds, such as Aspergillus niger, Trichoderma viride, etc. They can achieve a very good inhibition level through the treatment of items.

How Long Can The Effect of Antibacterial Masterbatch Last?

The effect of antibacterial active ingredients on microorganisms is physical, not chemically reacting with microorganisms, and the antibacterial substances will not be lost due to inhibition. As long as the antibacterial substances exist, their inhibitory effect will continue.

For polymers, antimicrobial ingredients can be better locked into the structure of the product than textiles, providing a more lasting antimicrobial effect. In many cases, it can even be considered the same as the product's life.

When You Have an Antimicrobial Masterbatch Project, What Issues do I Need to Consider?

Firstly, we need to understand what the product is being treated? Different products may have very different applications, so the requirements for antimicrobial masterbatch are different.

Secondly, we also need to understand in which countries or regions the antimicrobial treated products will be sold.

In European and American regulations, antimicrobial products are classified as biocides or pesticides and are subject to special supervision.

Different countries or regions have special regulatory lists or registration requirements for antimicrobial products that are allowed to be used. Violating these regulations may result in high fines, which is a very big risk and is easily overlooked by manufacturers or traders.

Thirdly, what are the expectations for antimicrobial? Is it required to be antibacterial alone, antifungal, or both? Different product application have different requirements for antimicrobial masterbatch. For example, a product used in a dry environment will have less consideration for mildew prevention, and the main consideration is to inhibit bacteria.

Some customers may say that they want both, but this will also involve considerations of processing costs. Our suggestion is to discuss before the project starts, determine the real needs, and balance the costs.

Of course, if the customer directly specifies the antibacterial requirements, or even the testing methods for the specified antibacterial products, this situation is relatively simple

Fourth, what is the processing technology of the product? In comparison, injection molding and casting require different considerations for the applicability of antibacterial products. The highest temperature during the processing process is also very critical for the selection of antibacterial products. Only suitable antibacterial products can achieve good antibacterial effects and realize product added value through proper processing.

Finally, there are some other considerations, such as product color, thickness, transparency, etc.

In general, antibacterial treatment is a relatively detailed process, and there are many factors that need to be taken into account to achieve an effective, safe, and cost-effective solution.

Applications of antibacterial masterbatch in various products

STANDARD has been engaged in research and development in the field of antibacterial masterbatch for many years, and has a long history of use with international antibacterial additive companies, with very successful experience and cases. We can provide full-process services from project conception to antibacterial realization.
