Why are rubber bands sticky?
Rubber bands are widely used. They are essential in our lives. When using rubber bands, we will find that rubber bands become sticky after being used for a long time. Why is that?
Rubber products are a kind of complex polymer composites, and their aging is closely related to their physical and chemical properties. Therefore, the aging of rubber products is a matter of time and cannot be avoided. Of course, its composition and the environment in which it exists also have a great impact.
Rubber bands will continue to oxidize when exposed to air, sunlight and other environments for a long time.
The flexibility of rubber bands has a certain range, and frequent overstretching will reduce their lifespan.
Solutions to prevent rubber bands from becoming sticky:
1. When using rubber bands, we should try to use them in a low temperature environment, and the storage environment should be light-proof and moisture-proof (relative humidity ≤ 60%). If the rubber bands are idle for a long time, they can be stored in the refrigerator to significantly extend their storage period.
2. If it does not affect the use, you can apply a thin layer of engine oil on it. The oily substance can isolate the air and reduce the oxidation rate.
3. Put a desiccant or deoxidizer when sealing.
4. Avoid contact with acidic and alkaline substances or high temperature environments.
Therefore, daoak recommends that in the process of using rubber bands, in order to avoid the phenomenon of rubber bands sticking, you should pay attention to the use environment or storage environment, and it is also necessary to buy good rubber bands.
