What is antibacterial masterbatch? What are the types of antibacterial masterbatch?

1. What is antibacterial masterbatch?

Antibacterial masterbatch is a kind of functional masterbatch. Various antibacterial agents are evenly dispersed in the matrix resin to form a concentrate. , namely antibacterial masterbatch.

In order to make the antibacterial agents in antibacterial materials exhibit good antibacterial properties, long-term antibacterial properties, and have stable performance during use, masterbatch technology is generally used to produce antibacterial plastics and antibacterial fibers in a certain amount. After the antibacterial masterbatch and corresponding resin particles are mixed, plastic parts, products and antibacterial fibers with antibacterial effects (bactericidal and bacteriostatic effects) on the surface can be produced according to the processing and molding methods of plastics and fibers.

With the development of the plastic industry and the improvement of people’s living standards, products such as telephones, bathtubs, toilets, toys, interior decoration materials, refrigerators, food packaging bags, plastic containers and public plastic products, It is extremely easy to be contaminated and breed bacteria, and mold can grow in dark places. In order to achieve the purpose of hygiene and deodorization, this has promoted the rapid development of antibacterial masterbatch and antibacterial plastic products.

2. What are the types of antibacterial masterbatch?

Antibacterial masterbatch is a functional masterbatch. The material components contain antibacterial agents or antibacterial agents that have antibacterial effects on bacteria or mold. Antifungal agent, which is made by mixing plastic and antibacterial agents through twin-screw equipment. There are many types of antibacterial masterbatch, generally there are two classification methods:

1. According to different types of polymers,

can be divided into PP (Polypropylene) antibacterial masterbatch, PE (polyethylene) antibacterial masterbatch, ABS (acrylonitrile-butadiene-styrene copolymer) antibacterial masterbatch, PC (polycarbonate) antibacterial masterbatch, PET (polyphenylene) Ethylene glycol diformate) antibacterial masterbatch, etc.

2. According to different application fields, it can be divided into two types: antibacterial plastic masterbatch and antibacterial fiber masterbatch. Antibacterial plastic masterbatch is mainly used in It is used in plastic extrusion, injection molding, blow molding and other molding processes; antibacterial fiber masterbatch is mainly used in the spinning of non-woven fabrics, polyester, polypropylene, nylon and other fibers.
