Antibacterial ability and flexibility of antimicrobial agents

May 02, 2019

Most of the polymeric materials during the operation of the antimicrobial agents are not subject to microbial attack in the pure state without the adjuvant. However, when various additives are added, it is possible to promote microbial growth leading to degradation of the polymer. Plasticizers, lubricants, and even some heat stabilizers are among these additives. The most common polymer that is susceptible to microbial attack is soft polyvinyl chloride because it usually contains a large amount of such additives.

In order to be able to improve the antimicrobial agents of the plastic when the antimicrobial agent is used, there are mainly two problems to be considered when performing the operation. 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.

Plasticizers for antimicrobial agents, such as phthalates, polyesters, citrates and oxidized hydrocarbons, only slightly increase the corrosion resistance of soft polyvinyl chloride, adipates, bismuth Diesters 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.
