UV resistance. What does it mean?

UV stands for ultraviolet light. Sunlight and UV lamps emit UV light. UV light generally degrades all plastics. PVC is one of the most resistant, however, over time, PVC plastic tubes will change color and become brittle. If you are using the protective tubes outside in the sun or in a room or closet with a lot of UV light, you will want to use UV rated tubes.UV rated tubes should last over 50 years. If you use NON-UV tubes, they will start to degrade within the first year. Depending on the intensity of the light, you will notice moderate discoloration (tanning) in 1-3 years. You will see heavy fading (brown) in 3-5 years and maximum fading (black) in 7-10 years. Any discoloration indicates that the plastic has been damaged. The darker the color, the more severe the damage. This degradation process can take years, however, any mechanical stress such as hitting it, stepping on it or walking over it can cause it to fail.Tubes are subjected to significant stress during their lifetime, which causes them to degrade. Once they have deteriorated to the point where they can no longer perform their functions or are unsafe for use, they usually require complete replacement. If the operational requirements are particularly severe, the tubes wear out faster and require replacement earlier, leading to higher costs and lost time for repair work. How do tube requirements relate to the importance of tube protection? The rigors of operational demands on tubes make the correct choice of cable protection critical. Reducing operational stress with tube protection reduces costs, improves durability by reducing waste, and improves tube durability and longevity.In conclusion, tubes used outdoors in direct sunlight often suffer damage from ultraviolet rays. The rate of degradation corresponds to the duration of exposure and the intensity of the light. Tubes used in these scenarios require specially designed protection to withstand UV radiation. If your business uses tubes, their reliable protection is vital to your productivity, safety, and success.
