Silicone hose is an elastic material widely used in medical, food, chemical and other industries, with good resistance to high temperature, corrosion and biocompatibility. However, the service life of silicone tubing is affected by a variety of factors. Understanding these factors and taking appropriate preventive measures can effectively extend the service life of silicone hose. The following are the main factors affecting the service life of silicone hose:

1. Temperature

Silicone hose has a wide range of operating temperatures, but prolonged exposure to extreme high or low temperatures may lead to aging and performance degradation of silicone hose. Excessively high temperatures can cause silicone tubing to harden and become brittle, while excessively low temperatures may cause it to lose its elasticity. Therefore, when using silicone tubing, try to control the ambient temperature within its tolerance range.

2. Chemical exposure

Although silicone tubing has good resistance to most chemicals, certain strong acids, alkalis and organic solvents can still damage it. Silicone hose may swell, dissolve or surface crack after long-term exposure to these chemicals. Therefore, before using silicone tubing, its compatibility with the chemicals it comes into contact with should be confirmed.

3. Mechanical stress

Silicone hose is often subjected to mechanical stresses such as stretching, compression and bending during use. Excessive mechanical stress can lead to fatigue damage to silicone hose, affecting its structural integrity and service life. Reasonable design of the installation and use of silicone hose to avoid frequent excessive stretching and bending can reduce the impact of mechanical stress.

4. Ultraviolet light and ozone

Silicone hose exposed to ultraviolet light and ozone for a long time may undergo aging phenomenon, which manifests itself as hardening of the surface, brittleness and loss of elasticity. This is particularly noticeable in silicone hoses for outdoor use. To avoid this, choose silicone materials with added UV and ozone resistant agents, or take shading and protective measures.

5. Cleaning and maintenance

Silicone hoses require regular cleaning and maintenance during use to remove adhering dirt and chemical residues. Use neutral cleaners and soft brushes for cleaning, and avoid using tools containing abrasives to prevent scratches and abrasions. Regularly check the condition of the silicone hose and replace any parts that appear to be deteriorated or damaged in a timely manner.

6. Storage conditions

Unused silicone tubing should be stored in a dry, well-ventilated environment, avoiding direct sunlight and high temperature and humidity. Heavy objects should be avoided to press on the silicone tube during storage to avoid deformation and damage. Proper storage conditions can effectively extend the service life of silicone tubing.

Conclusion

The service life of silicone hose is affected by many factors such as temperature, chemical exposure, mechanical stress, UV and ozone, cleaning and maintenance, and storage conditions. By reasonably controlling the use environment, regular cleaning and maintenance, proper storage and avoiding unnecessary mechanical stress, the service life of silicone tubing can be significantly extended to ensure its reliability and stability in various applications.
