Are PP plastic barrels prone to wear, fading or deformation during long-term use?

PP plastic barrels generally show high durability during long-term use, but whether they are easy to wear, fade or deform is closely related to many factors, such as the use environment, the type of items stored, and whether they are properly maintained.
Under normal use, PP plastic barrels have strong wear resistance. Because PP material has high hardness and scratch resistance, the barrel body will not be significantly worn due to slight collisions or friction in most daily use environments. For storing heavier or rough items, although there may be slight scratches on the surface of the barrel, these will not significantly affect the overall structure and function of the barrel. Especially when storing items such as liquids or particles that do not directly rub against the barrel wall, wear is usually less.
In the case of frequent movement, impact or contact with hard objects, the surface of PP plastic barrels may be slightly worn. This wear usually manifests as surface scratches or slight dents. Although it does not affect the storage capacity or overall function of the barrel, it may affect its aesthetics from the appearance. Especially in high-frequency handling or transportation, the rate of wear may accelerate without proper protection measures.
Regarding the fading problem, PP plastic barrels have relatively good fading resistance. PP material itself has strong UV resistance, so under normal indoor use, the barrel's color retention ability is usually strong. However, PP plastic barrels that are exposed to sunlight or UV for a long time may begin to fade, especially barrels that have not been UV treated. In an environment where the outdoors or direct sunlight is exposed, long-term use may cause the barrel's color to gradually fade, or even color difference. This fading phenomenon mainly occurs on low-quality or non-UV-resistant plastic barrels, especially when exposed to strong sunlight for a long time.
Regarding deformation, PP plastic barrels have good shape retention at normal temperatures, but if they are exposed to high temperatures for a long time, their deformation risk will increase. Although PP plastic itself has good temperature resistance and can generally withstand temperatures of around 80°C, long-term exposure to higher temperatures (such as under the scorching sun or in an environment where high-temperature items are stored) may cause the plastic barrel to soften, deform or bend. In this case, the barrel body may lose its original rigidity and structural integrity, affecting its performance. Especially in a high-temperature environment, the load-bearing capacity of PP plastic barrels will also be affected, and the barrel wall may become thinner and irregular in shape.
The durability of PP plastic barrels is also affected by the nature of the stored items. For example, certain chemicals, acidic or alkaline substances may cause chemical reactions to PP plastic barrels, thereby accelerating their aging, embrittlement or deformation. Although PP materials are excellent in chemical corrosion resistance, long-term contact with certain highly corrosive substances may affect the structural stability of the barrel.

In summary, PP plastic barrels are very durable under normal use conditions, but under extreme environmental conditions, factors such as high temperature, strong ultraviolet rays or chemical contact may cause them to wear, fade or deform. Therefore, in order to extend the service life of PP plastic barrels, it is recommended to use them in a suitable environment, clean and maintain them regularly, and avoid long-term exposure to adverse environmental factors.
