No matter what product it is, it will definitely change after we use it for a long time. For example, our tape will have a good performance after aging. We must take some measures to extend the service life of the product.

1. Oxygen, due to its 21% oxygen content in the air, has the characteristic of accelerating material oxidation. It is very active forms a rapid oxidation of PET film, which then leads to the PET film becoming "old".

2. Ultraviolet rays (sunlight). Ultraviolet radiation has high temperature characteristics can quickly distinguish viscous substances. Pet films exposed to sunlight for a long time will be distinguished by them, leading to aging of the PET film.

3. Metals, especially brass rust, can react with any organic compound substances in daily life, especially brass rust. PET film contains organic compounds, which can cause PET film to deteriorate..

4. Bleach, its main component is calcium oxide, which contains calcium elements that can react with organic compounds.

5. Plasticizers are mainly used to soften plastics, most rubber products contain plasticizers. With the passage of time, the proportion of plasticizers in its substance will increase, leading to aging of PET films, etc. Under the long-term influence of various factors mentioned above, PET film will deteriorate, soften, solidify, lose its viscosity.

The above points are the reasons for the aging of PVC film. That's all for today. If you would like to learn more information, please visit our website to learn more.
