How Much Do You Know about Silicone Tubing?

  • by

Silicone tubing is a very important peristaltic pump accessory and one of the most commonly used peristaltic pump tubing. Silicone tubing is also very common in daily life, but do you really understand it?

To truly understand silicone tubing, let’s first talk about the raw materials of it.

Silicon Rubber

Silicone rubber refers to rubber whose main chain is composed of alternating silicon and oxygen atoms, with two organic groups connected to the silicon atoms.

Ordinary silicone rubber is mainly composed of siloxane chains containing methyl groups and a small amount of vinyl groups. Silicone rubber molecule has a helical structure with large bond angle and bond length ratio. This unique molecular structure makes it have high thermal stability.

Silicone rubber has good breathability and the oxygen permeability is the highest among synthetic polymers. In addition, silicone rubber also has prominent characteristics of physiological inertness and does not cause coagulation, making it widely used in the medical field.

Definition of Silicone Tubing

The peristaltic pump silicone tube is a soft tube made of silicone with different performance based on the power performance and conveying material of the peristaltic pump. Add silicone rubber raw rubber to a double roller rubber mixer or a closed kneading machine, gradually add white carbon black and other additives, and repeatedly refine evenly. According to industry product technical standards, the product is made by extrusion.

Silicone Tube

There are two forms of domestic peristaltic pump silicone tubing: one is platinum sulfide silicone tubing, which is soft, slightly transparent, with a smooth inner wall, low protein adhesion, and low protein permeability, suitable for the pharmaceutical and biological fields;

Another type is silicone peroxide hose, which is soft, slightly transparent, with a smooth inner wall, long service life, and can transport fluids with special properties such as corrosiveness.

Characteristics of Silicone Tubing

Silicone tubes have excellent resistance to high and low temperatures, good physiological stability, and can withstand repeated and harsh disinfection conditions, with excellent resilience.

Functional characteristics

1.Has excellent biocompatibility;

2.Odorless and non-toxic, without plasticizers, with minimal precipitation;

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

4.Good elasticity, able to quickly restore shape after radial compression (Shore hardness 50-55);

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

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

7.The temperature resistance range under static state is -50~230 ℃, and the temperature resistance under working state is -40~100 ℃;

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