Antibacterial ability and type requirements of antimicrobial agents

Antimicrobial agents, fungicides, fungicides and the like are effectively referred to as preservatives. Regardless of the terminology used, the function of the preservative is to protect the polymeric material from microbial attack. The polymer is affected by microbial attack and will affect the appearance.

Antimicrobial Agents In order to improve the antibacterial ability of plastics, there are two main problems to be considered. The first is the type of additives used in the formulation. Reducing the amount of additives known to be susceptible to microbial attack can give plastics a certain antibacterial capability. Plasticizers are used to improve the flexibility of PVC. Considering its antibacterial properties when using plasticizers, it will help to reduce the degree of plastic corrosion.

Practice has shown that certain plasticizers, such as phthalates, polyesters, citrates and oxidized hydrocarbons, only slightly increase the corrosion resistance of soft polyvinyl chloride; adipates, Sebacate and pentaerythritol esters have moderate levels of ablation, as are sebacates, epoxidized fats (bean oil and tall oil), and glycolates. The use of non-migratory plasticizers such as tris-toluene phosphate and polyester also helps to reduce the nutrients on which the microbes depend on the surface of the polymer.www.china-zhufengchem.com
