Xiaomi patented silicone leather

Information from the China National Intellectual Property Administration shows that Beijing Xiaomi Mobile Software Co., Ltd. has applied for a patent titled “An Organic Silicone Leather and Its Production Method, Housing, and Electronic Device,” with publication number CN120556287A and publication date August 2025.

Background technology: Silicone is gradually being used as a compound due to its excellent softness, water resistance, stain resistance, weather aging resistance, chemical stability, and physiological inertness finished leather coating and electronic packaging. However, the inert surface of silicone makes it combined finished leather Bonding the base fabric becomes difficult, especially for base fabrics formed from high-temperature calcined materials such as glass fiber and carbon fiber. Due to the high hardness of the fiber material, it is difficult to bond with organosilicon, resulting in poor bonding reliability between silicone and fiber materials.

Abstract: The present disclosure provides an organosilicone leather, its manufacturing method, a casing, and an electronic device. Organosilicone leather includes a layered woven base fabric layer, an adhesive layer, and an organosilicon layer. The adhesive layer includes a first adhesive layer and a second adhesive layer arranged in a lamination. The first adhesive layer covers the woven base fabric layer, the material of the first adhesive layer includes thermoplastic adhesive or thermosetting adhesive, and the organosilicone layer covers the second adhesive layer in the adhesive layer. In the silicone leather provided by the present disclosure, a bonding layer is provided between the woven base fabric layer and the silicone layer, and the material of the first adhesive layer in the bonding layer in contact with the woven base fabric layer includes a thermosetting adhesive or coupling agent that has good adhesion to the woven base fabric layer, thereby providing good interfacial bonding strength between the woven base fabric layer and the adhesive layer. At the same time, the silicone layer contacts and bonds with the second adhesive layer, giving the silicone layer good bonding strength to the woven base fabric layer, making it difficult to peel off or fall off.

As people’s attention to environmental protection and sustainable development continues to grow, silicone materials are gradually becoming a combination finished leather and an important choice in the electronic packaging field. This material is increasingly favored by brands for its excellent softness, water resistance, stain resistance, resistance to climate aging, and chemical stability. However, the inert surface properties of silicone make it difficult to combine with the silicone surface finished leather Challenges arise during the bonding process of the base fabric, especially when using materials such as glass fiber or carbon fiber formed by high-temperature calcination, where bonding reliability is often insufficient.

Xiaomi’s patent proposes an innovative solution to this technical challenge. The core lies in achieving stronger bonding strength through layered woven base fabric, bonding layers, and silicone layers. In particular, the bonding layer in the patent includes a first bonding layer and a second bonding layer, with the first bonding layer using thermoplastic adhesive or thermosetting adhesive materials to ensure good adhesion to the woven base fabric layer.

In this patent, the design of the bonding layer between the woven base fabric layer and the silicone layer is very ingenious. The material of the first bonding layer not only adheres well to the base fabric layer, but the silicone layer of the second bonding layer also provides excellent adhesion, making the entire structure less likely to peel off or fall off during use. This new silicone leather design not only enhances product durability but also provides higher quality assurance for the appearance and feel of future electronic devices.

It is foreseeable that as Xiaomi further explores the field of silicone materials, its electronic products may lead new trends in the market. Combined with current consumer demands for environmentally friendly and high-performance products, the application of this silicone leather will greatly enhance Xiaomi’s brand competitiveness. In the future, consumers may pay more attention to the environmental friendliness and durability of their materials when purchasing phones, tablets, and other digital products.

Overall, Xiaomi’s silicone leather patent not only reflects its technological innovation but also serves as an important inspiration for the industry’s future development. With continuous technological advancement, the choice and application of materials will have a profound impact on the design and functionality of 3C digital products. Consumers look forward to Xiaomi bringing more innovative products, and also to see more brands make breakthroughs in material technology, pushing the entire industry toward higher standards.
