Low toxicity: Zinc is an essential trace element for the human body (the recommended daily intake is about 8-11 mg). A small amount of migration is usually harmless, and its safety is higher than that of silver ions (which may accumulate) or organic antibacterial agents (such as triclosan). Food-grade certification: Complies with the standards of food contact materials in various countries (such as FDA, EU 10/2011, and Chinese GB 4806), and is suitable for long-term use.

Surface coating: Suitable for post-processing antibacterial treatment. The adoption of plasma pretreatment technology to enhance the surface energy of TPE films can improve the adhesion of silver nanoparticle coatings.

In terms of composition, paper glue usually contains nutrients such as starch, protein and oil, which are precisely the "delicacies" needed for the growth and reproduction of mold. For instance, common glue is composed of polyvinyl alcohol, white latex, sodium stearate, talcum powder, urea, ethylene glycol, sucrose, flavoring, water, etc. Among them, components such as sucrose and protein provide rich nutritional sources for mold.

Silver ions/copper ions: Achieve broad-spectrum antibacterial effects by destroying the cell structure of microorganisms and are suitable for plastic handles. When adding, the dosage should be controlled (such as 0.3%-0.8%) to avoid the risk of yellowing or toxicity caused by the precipitation of metal ions. Nano zinc antibacterial agent: Utilizing nano zinc oxide technology, it is safe, environmentally friendly and has a high antibacterial efficiency. It is suitable for food contact grade materials (such as toothbrush handles) and can inhibit Escherichia coli, Staphylococcus aureus, etc.

Nanomaterials such as nano-zinc oxide and nano-titanium dioxide photocatalyze the generation of reactive oxygen species, which destroy the structure of biological cells. Or it can suppress adhesion through physical action, which is highly efficient, environmentally friendly and multi-functional. The preparation process is complex and the cost is relatively high

Driven by the dual impetus of enhanced public health awareness and the iteration of antibacterial technologies, the integration of oil-based coatings and silver-ion antibacterial agents is becoming an innovative direction in fields such as construction, healthcare, and food processing.

The processing temperature of PPR pipes is relatively high (usually 200-260°C), so high-temperature resistant and stable antibacterial agents need to be selected. Inorganic antibacterial agent

Adding antibacterial agents to ABS materials is an important means to enhance their antibacterial performance and expand their application fields. The following is an introduction from several dimensions including the types of antibacterial agents, application advantages, and application fields: Types of antibacterial agents for ABS materials

Types and mechanisms of action of antibacterial agents Silver ion antibacterial agent

In an environment with a temperature of 25-35℃ and a humidity of over 70%, microorganisms such as mold and yeast can form colonies within 24 hours, and their metabolic products can cause the following deterioration of the coating:
