1. What is pp antibacterial masterbatch
Antibacterial masterbatch is a high molecular polymer material (polyethylene, polypropylene, etc.) and a certain proportion of antibacterial agent (inorganic Antibacterial agents, organic antibacterial agents, natural antibacterial agents, etc.) are mixed and extruded by a screw machine, and are used for injection molding, blow molding, spinning and other molding processes.
There are many types of antibacterial masterbatch, and pp antibacterial masterbatch is one of them, that is, polypropylene antibacterial masterbatch.
2. The function and use of pp antibacterial masterbatch
The main function of pp antibacterial masterbatch is to make polypropylene plastic parts or fibers (polypropylene) have Antibacterial function. During the molding process, PP antibacterial masterbatch is added to the raw materials at a ratio of 3% to 5%, so that the finished product has antibacterial function and can inhibit and kill microorganisms such as Escherichia coli, Staphylococcus aureus and mold. Function. The main uses of pp antibacterial masterbatch are:
1. Antibacterial treatment of PP (polypropylene) plastic parts such as household appliances and daily necessities. For example, home appliances such as refrigerators, air conditioners, washing machines, and humidifiers are antibacterial, and household plastics such as cutting boards, lunch boxes, and trash cans are antibacterial.
2. PP plastic films and bags are antibacterial. Such as our common antibacterial food preservation films, antibacterial food preservation bags, etc.
3. Polypropylene fiber is antibacterial, such as antibacterial polypropylene, antibacterial non-woven fabrics, etc.
3. Product characteristics of pp antibacterial masterbatch
1. Appearance: uniform size, good plasticization, consistent color, and no obvious impurities.
2. Antibacterial active ingredients: organic antibacterial agent; antibacterial agent content: 20%; broad-spectrum antibacterial: rapidly inhibit E. coli, Staphylococcus aureus, Streptococcus albicans, mold, etc. up to 99% or more .
3. Long-lasting effect: The antibacterial life span is synchronized with the product life span.
4. Economical and affordable: The product is efficient, with a small amount of addition and obvious effects.
5. Good thermal stability, high temperature resistance and not easy to change color. Good compatibility and dispersion. It does not change the original plastic processing technology, nor does it change the original function of the product.
6. High safety and environmentally friendly.
7. Dispersion uniformity: There are no solid particles visible to the naked eye on the surface of products added with antibacterial masterbatch.
