How to choose the medical grade silicone tube

Introduction: what is a medical-grade silicone tube? 

A silicone tube is a medical device used to transfer fluids or air from one location to another. There are many different types of silicone tubes, but the most common are medical-grade silicone tubes. These tubes are made of a soft, flexible material that can be easily bent and twisted. They are also resistant to heat and cold, making them ideal for use in medical procedures.

There are many other applications for silicone tubes, including food processing. They can be used to make containers for liquids, including syrups and soft drinks. The flexible material of these tubes makes them ideal for piping foods, as well as transferring liquids between two containers.

How do choose the silicone tube used in medical devices?

First of all, the whole process of selecting medical silicone rubber is very complicated. The medical mechanical interior engineer of medical machinery must consider physical properties, such as specifications and strength, visibility, or the need for radiopaque patterns. And its excellent design solutions such as kink resistance.

In addition, when selecting embedding silicone tubes, the purity of the raw material, organic chemistry and biocompatibility, specifications, and performance must be considered, as this factor plays a leading role in the characteristics of the product.

How do you choose a medical-grade silicone tube? 

When looking for a medical-grade silicone tube manufacturer, there are a few things you need to consider. The first is the type of silicone tubing you need. There are several types of silicone tubing available on the market, but only a few are medical grade. The second consideration is the size of tubing you need. The size will vary depending on the application. The third consideration is the temperature range that the tubing will be used in. Make sure to select tubing that can withstand the desired temperature range. Finally, ask your supplier for verification that the silicone tubing is indeed medical grade. 

Physical properties:

When selecting silicone tubes, especially when the design of medical machinery tends to be small and medium-sized equipment and drug transportation equipment, the key physical properties need to be considered are specifications. At this stage, the size of the embedding glutinous rubber camp have no 0.07 × 0.01 feet. However, not all dealers have the ability to bring their products to the market immediately, so which should be kept in mind during the whole process of selecting dealers.

Tear compressive strength and tensile elongation of mechanical equipment elements:

If there are fine crack marks in the silicone tube, its breaking compressive strength will seriously affect its improvement level. The amount of stretch is related to the ductility of the flexible pipe, which is a physical property of the balloon hose that must be considered.

Ultimately, it is important to carefully assess the surface finish quality of the pipeline. In general, low friction on the surface of the silicone tube is very important for specific applications. Although the surface coating can reduce the adhesion of the silicone itself, the coating must meet the requirements of biocompatibility, especially when the machine equipment is likely to touch and enter the body cells. Although the tube has a high biocompatibility.

However, it is still necessary to select silicone grades and additives according to the application conditions. Depending on the circumstances, in some cases of high vaporization regulations, visibility must be taken into account for some types of medical devices, such as pharmaceutical media that are transported to the body, or expelled from the body to the outside. mechanical equipment.

Although the silicone itself is completely transparent, some silicone fillers are added to increase the hardness, and barium sulfate (BaSO4) and titanium dioxide (TiO2) are added to adapting to the develop trends, reduce or clear the clarity, and then endanger the clinician to observe the liquid whether it is according to the estimated movement trajectory fluidity.


All in all, there are situations in which medical mechanical interior designers look to make the silicone tube more visible in the body, for example, when applying X-ray or fluoroscopic lenses to properly guide medical devices across the body. Barium can be added to the silicone tube and not only can be seen in the subcutaneous tissue, but also the liquid state can be observed to verify fluidity.

In addition, a higher percentage of barium additives can be used to ensure that the conduits conform to the human skeleton and assist the surgeon to view the situation that placing the hose in the spine.If you want to find a medical-grade silicone tube manufacturer, please contact Suconvey Rubber for free.
