How Much Do You Know About Silicone Tube?

  • by

Peristaltic pump is also called hose pump, so the tube plays an important role in the working process of peristaltic pump. When the peristaltic pump transmits liquid, the liquid only contact the inner wall of the peristaltic pump tube and will not contact other parts such as the pump head and so on. So the tube can protect the cleanliness of the liquid. We can change the size of the tube to realize the transmission of different flows, transfer and dispensing functions. Peristaltic pump tube are made of different materials, and silicone tube is the most commonly used one.

So what is silicone rubber?

Silicone rubber refers to the rubber whose main chain is composed of silicon and oxygen atoms alternately, and the silicon atom is connected with two organic groups. Ordinary silicone rubber is mainly composed of silicone links containing methyl and a small amount of vinyl.

Silicone rubber molecules have a helical structure with large bond angle and bond length. This unique molecular structure makes it have high thermal stability.

Silicone rubber has good air permeability, and the oxygen transmittance is the highest in synthetic polymers. In addition, silicone rubber is also physiologically inert and will not cause coagulation. It is widely used in the medical field.

What is silicone tube?

Peristaltic pump silicone tube is a soft tube made of silica gel with different properties according to the power of peristaltic pump and different conveying materials. The silicone rubber raw rubber is added to the double roll rubber mixer or closed kneader, gradually added with silica and other additives, repeatedly refined evenly, and extruded into products according to the requirements of industrial product technical standards.

There are two types of silicone tube made in China for peristaltic pump:

One is platinum vulcanized silicone tube, which is soft, slightly transparent, smooth inner wall, low protein adhesion and low protein penetration. It is suitable for pharmaceutical and biological fields;

The other one is silicon peroxide hose, which is soft, slightly transparent, smooth inner wall and long service life. It can transport fluids with special properties such as corrosive liquid.

The characteristics of silicone tube

Silicone tube has excellent high temperature and low temperature resistance, good physiological stability, and can withstand repeated and harsh disinfection conditions, with excellent resilience.

Functional features:

1.Excellent biocompatibility;

2.Tasteless, non-toxic, no plasticizer, little precipitate;

3.The inner wall is very smooth and has good antibacterial performance;

4.It has good elasticity and can quickly recover its shape after radial compression (Shore hardness 50 ~ 55);

5.Weathering resistance, ozone resistance, radiation resistance and aging resistance;

6.Suitable for neutral liquids, weak acids, weak bases and some low concentration solvents;

7.The temperature resistance range is – 50 ~ 230 ℃ in static state and – 40 ~ 100 ℃ in working state;

8.Hot water and distilled water can be used for cleaning, high temperature and high pressure, ethylene oxide, gamma ray sterilization.
