Foamed silicone is a porous elastic material made from silicone rubber as the base material through physical or chemical foaming processes. Its interior is composed of a large number of closed or semi closed bubble structures, which endow it with characteristics such as lightweight, softness, high and low temperature resistance, aging resistance, and good insulation. In the manufacturing process, organic silicone rubber is usually used as the substrate, and foaming agents, crosslinking agents, fillers and other additives are added. After mixing, molding, vulcanization, foaming and other processes, it is completed.

Foam silicone has a wide range of densities that can be adjusted according to demand, ranging from low-density lightweight materials to high-density cushioning materials. Its physical properties are stable, able to maintain elasticity within the temperature range of -50 ℃ to 250 ℃, and not easily deformed or brittle. In terms of chemical stability, it has corrosion resistance to most acids, bases, salts, and organic solvents, and is not prone to chemical reactions. In the application field, foam silicone is widely used in sealing, shock absorption, heat insulation, sound insulation and other scenarios.

For example, in the construction industry, it can be used as door and window sealing strips, pipeline insulation materials; In the field of electronic appliances, it is used for buffering gaskets and insulating gaskets; In the automotive industry, it is used for engine compartment sealing and seat cushioning; In the medical field, due to its non-toxic, odorless, and good biocompatibility, it can be made into medical catheters and prosthesis filling materials. In addition, foam silicone also has processability and can be made into various shapes through molding, extrusion, injection molding and other processes to meet the design needs of different products.

With the advancement of technology, its performance continues to be optimized and its application scope continues to expand, becoming an indispensable functional material in industrial production and daily life.
