Leather products are loved by people for their unique texture, durability and beauty, but do you know how to make leather both soft and strong? The application of fluorinated silicone oil in the field of leather chemicals is the key to unlocking this secret. Here is a detailed introduction for you.



In the long process of leather processing, softening is an important step in determining the quality of leather. Too hard leather is not only uncomfortable to wear, but also prone to cracks at the bends, greatly shortening its service life; while ordinary softeners can improve softness to a certain extent, the effect is often not long-lasting and it is difficult to meet the needs of high-quality leather. At this time, fluorinated silicone oil has become the "star additive" of the leather chemical industry with its unique chemical structure and performance advantages.

In the fluorine-containing silicone oil molecule, the fluorine atom has extremely strong electronegativity and a small atomic radius, which gives it excellent surface activity. When fluorine-containing silicone oil is used in leather processing, it will quickly form a uniform protective film on the surface of the leather fiber. This film can significantly reduce the friction coefficient between the leather fibers, just like adding countless tiny "lubricants" between the fibers, making the leather extremely soft and smooth. Clothes and bags made of leather treated with fluorine-containing silicone oil will not feel stiff when used close to the body, bringing an extremely comfortable experience.

In addition to the improvement of softness, the enhancement of leather elasticity and toughness by fluorinated silicone oil is also worth noting. In daily use, leather will inevitably experience various external forces such as bending and stretching. Fluorinated silicone oil can penetrate into the leather fibers, interact with the fiber molecules, and enhance the bonding force between molecules, thereby improving the overall strength of the leather. In repeated bending tests, the probability of cracks and wear on leather treated with fluorinated silicone oil is much lower than that of untreated leather, and its durability has been greatly improved.

In addition, fluorinated silicone oil also has good chemical stability and weather resistance. The protective film it can form on the leather surface can not only resist the erosion of moisture and stains in the external environment, but also slow down the aging effect of ultraviolet rays on the leather, allowing leather products to maintain bright color and good performance for a long time.
