Polyurethane leather is more water-resistant than genuine leather
Polyurethane (PU) leather is a synthetic leather substitute that emerged as a byproduct of broader research and development in synthetic materials throughout the 20th century. It is commonly used as an alternative to genuine leather and provides a similar look and feel at a lower price point.
PU leather is more water-resistant than genuine leather. This is due to the PU varnish, which gives it a thicker, water-resistant, and more durable finish. The level of water resistance in PU leather can vary depending on the specific product and manufacturing process. While it is more water-resistant than genuine leather, it is not completely waterproof.
The process of making PU leather involves dipping split leather (animal hide that has been split into thinner sheets) into PU resin. This gives it the tough, waterproof features of leather at half the cost. PU leather is also lighter than genuine leather, making it ideal for sportier shoes.
One way to test the difference in water resistance between PU leather and genuine leather is to perform a water test. By dabbing a few drops of water on the material, you will see that genuine leather absorbs the water, while PU leather does not.
Despite its advantages in water resistance, PU leather has some significant drawbacks. One of the main concerns is its lack of durability compared to genuine leather. With frequent use, PU leather can easily crack and peel, reducing its lifespan. Additionally, the production of PU leather often involves the use of toxic chemicals and solvents, which can have a negative impact on the environment.
