Ozone can cause the aging of the rubber tube. This is because ozone is more oxidizing and much larger than oxygen. However, the ozone content in the air is not too much, and only in certain places will it affect the rubber tube. Therefore, as long as the working environment and storage environment of the main rubber tube, the harm caused by ozone can be avoided. Velon DSM600 has good ozone resistant due to our customized fulmar of rubber materials and hose construct design.

There are some other reasons can cause the aging of rubber hoses. Such as oxidation reaction. The oxidation reaction is one of the most important reasons for the aging of the rubber tube. This is because oxygen will oxidize with the molecules in the rubber, causing the molecular chain of the rubber to break or excessive cross-linking, which will cause the performance of the rubber to gradually weaken until the rubber is completely aging. But the air always contains oxygen, so the aging (oxidation reaction) of rubber is going on all the time.

Then there is moisture. Although the rubber hoses are waterproof, long-term work in a dark and humid environment or long-term immersion in water will also cause the rubber hoses to age. This is because some auxiliary agents are added to the rubber tube during the production process, and some of these auxiliary agents will have water-soluble substances, so if they are in contact with water for a long time, they will be hydrolyzed, which will not only reduce the rubber tube’s Performance, it may also cause damage to the structure of the hose.

Finally, there is the factor of temperature. Each material of rubber tube has its own temperature range that is most suitable for use. General rubber will become hard and brittle when the temperature is too low. This rubber is easy to be damaged and needs to be handled with care. If the temperature rises, UI and vulcanized rubber will cause the unreacted vulcanizing agent in the material to continue to harden. As for non-vulcanized rubber, its properties such as hardness and elasticity will also decrease, which is not conducive to The transportation of materials. Moreover, the increase in temperature will promote the reaction speed of the oxidation reaction between oxygen and the rubber hose, and accelerate the aging of the rubber hose.
