The peeling phenomenon of PU leather is related to material quality, usage habits, and environmental factors.

The fundamental reason for its peeling is as follows:

1. Material characteristic limitations

PU leather is essentially a synthetic leather with a polyurethane coating covering the fiber substrate. The adhesive layer between the coating and the base fabric will separate over time, resulting in surface peeling.

2. Accelerated aging of the environment

High temperature or exposure to sunlight: Direct ultraviolet radiation can cause the coating to become brittle and crack (there is a high risk of placing it in cars or on balconies in summer).

Moisture: Moisture infiltration can damage the adhesive layer, especially during the rainy season or in coastal areas where it is prone to mold and delamination.

Large temperature difference: Frequent thermal expansion and contraction lead to coating cracking.

3. Physical wear and tear

Frequent friction areas, such as bag edges and sofa armrests, can accelerate coating detachment due to scratching.

Good quality PU leather has a peeling cycle of about 3-5 years (normal phenomenon), cheap PU leather has a peeling cycle of about 1-3 years, and high-frequency PU leather has a peeling cycle of within two years.
