Changshu da plastic products factory talk about PP antibacterial agent how to develop smoothly

Polypropylene plastic pipe has been widely used but there is also a fatal defects & ndash; — Hanging clouds fungal growth, because of the polypropylene plastics is a kind of organic polymer materials are easy to be microbial erosion, so in the use of the surface after a period of time can produce a layer of creamy, and plastic pipe once the installation is extremely difficult to clean up. So antibacterial agent has become a very important a plastic additives.

PP antibacterial material is the core component of antimicrobials, according to the chemical composition of roughly divided into three classes of inorganic, organic and natural, natural antimicrobials are constrained by the raw materials and processing conditions cannot achieve large-scale market at present. Organic antibacterial agent has the advantages of faster sterilization element, wide range of antibacterial, but poor heat resistance, easy leakage, stripping toxic, short service life. The infinite antibacterial agent, good heat resistance, durability, safety to organic antibacterial agent, but the price is higher can't quickly kill bacteria, and almost no inhibition effect on fungi, mold.

China on the basis of long-term research developed a molecular assembly antibacterial new technology, through the selection of highly effective broad-spectrum antibacterial activity, harmless to the human body, also thermal models of antimicrobial function group, through its block, grafting functional groups such as chemical way assembly onto the molecular chains of matrix resin and antibacterial masterbatch is obtained.

the antimicrobial properties of antimicrobial plastics should has the characteristics of high efficiency, broad spectrum, persistent, and should be non-toxic tasteless, no impact on the environment. Good should also cooperate with all kinds of plastic, not more plastic in various additives in chemical reactions, do not collect heat and light color effect.
