In the medical field, catheters, as key devices connecting the inside and outside of the human body or different parts within the body, are widely used in scenarios such as drainage, drug administration, interventional diagnosis and treatment, and monitoring. However, the direct contact of the catheter with body fluids and blood makes it a breeding ground for microorganisms, significantly increasing the risk of nosocomial infection. According to statistics, the global medical expenses caused by catheter-related infections exceed several billion US dollars each year, among which urinary tract infections associated with catheters and central venous catheter-related bloodstream infections account for a relatively high proportion. Therefore, adding antibacterial agents in catheter production has become a core strategy for enhancing medical safety. I. The Core Role of Antibacterial Agents in Catheter Production

If the plastic powder needs to undergo antibacterial treatment, Tianshi Landun Silver Ion Antibacterial Agent can be added. The characteristics, antibacterial principle and addition suggestions of the powder coating antibacterial agent are as follows:

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.

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:

Polypropylene (PP), as an important general-purpose plastic, features excellent mechanical properties, electrical insulation, thermal stability and processing performance

The bactericide KATHON WT has antiseptic properties, which make it play a pivotal role in many fields.

Fungicides, also known as biocides, bactericides, microbicides, etc., usually refer to chemical agents that can effectively control or kill microorganisms in the water system - bacteria, fungi and algae.

Generally, factories add less or no preservatives in winter and spring, creating favorable conditions and time for the breeding and reproduction of microorganisms. The late spring and summer solstice are one of the most suitable growth climates for microorganisms.
