Silicone leather is an innovative type of synthetic leather. It uses textile fabric or fiber base material as its skeleton, and through processes such as coating, laminating, or impregnation, liquid silicone rubber is compounded onto its surface or throughout its structure, followed by vulcanization and curing. It is not made from animal leather but rather represents a high-tech composite material designed to combine the exceptional properties of silicone with the texture and applications of leather.

A coating is a material applied to the surface of an object that, after drying or curing, forms a continuous film with specific properties. This film is referred to as the coating or paint film. It serves not only as a cosmetic "makeup" but also as a "functional garment" that protects the substrate and enhances its performance.

Silicone (typically referring to liquid silicone rubber) is an exceptionally important high-performance material, renowned for its biocompatibility, flexibility, high-temperature resistance, chemical stability, and safety. Traditionally, silicone products are manufactured through mold injection molding, which involves high costs and long lead times for small-batch or complex structural production. 3D printing technology offers a revolutionary solution for directly and mold-free fabrication of complex silicone structures.

Silicone interface materials are a category of silicone products specifically designed to fill microscopic gaps between two contacting surfaces. Their core functions are to eliminate air, establish efficient thermal or electrical connection pathways, and provide cushioning protection. These materials are available in various forms, including thermal greases, gels, pads, and phase change materials, and are widely used in applications requiring thermal management, electrical insulation, or stress protection.

Silicone-modified engineering plastics do not refer to pure silicone plastics, but rather to a category of high-performance specialty plastics. These materials incorporate polysiloxane (the core component of silicone) in the form of molecular segments or microspheres into traditional engineering plastic matrices (such as PC, PA, PBT, etc.) through copolymerization or blending technologies, significantly enhancing their fundamental properties.

Silicone adhesives are a special category of adhesives formulated with polysiloxane as the base polymer. Their core molecular structure—the silicon-oxygen (Si–O) bond—combines the stability of inorganic materials with the flexibility of organic compounds. This unique composition grants them exceptional properties absent in most conventional adhesives (such as epoxy, acrylate, and polyurethane).

Silicones, particularly medical-grade high-purity silicone rubber, rank among the most widely used polymeric materials in the biomedical field. Their backbone consists of silicon-oxygen (Si–O) bonds, with organic groups (such as methyl) attached as side chains. This unique structure imparts unparalleled properties, enabling them to safely and permanently contact human tissues, body fluids, and blood.
