If you were to draw an application map for solid silicone rubber, you would find that it covers almost every corner of modern industry. From silicone spatulas in your kitchen, to seals for aircraft engines at altitudes of tens of thousands of meters, from O-rings in deep-sea oil and gas pipelines, to composite insulators on ultra-high voltage power grids, solid silicone rubber plays an irreplaceable role in countless critical scenarios with its unique performance combination.

In the power industry, the position of solid silicone rubber is almost monopolistic. The composite insulators used in high-voltage and ultra high voltage transmission lines have their umbrella skirts completely molded from solid silicone rubber. Compared with traditional ceramic insulators, silicone rubber insulators are lightweight, less prone to breakage, and have excellent anti pollution and flashover performance. They can still maintain reliable insulation performance in harsh environments such as icing and salt spray. At present, the utilization rate of silicon rubber insulators in ultra-high voltage power lines worldwide has exceeded 90%. It can be said that without solid silicon rubber, there would be no modern ultra-high voltage power grid. In addition, solid silicone rubber is widely used in stress cones, insulation sheaths, seals, and other components of cable accessories. Its resistance to corona discharge and aging ensures the safe operation of cable systems for decades.

In the automotive industry, solid silicone rubber is mainly used for various types of seals and shock absorbers. High temperature seals such as engine valve cover gasket, oil pan gasket, intake manifold gasket, as well as dynamic components such as dust cover, bellows, shock absorber liner, etc., are typical applications of solid silicone rubber. With the rise of new energy vehicles, new demands such as battery pack sealing, high-voltage wire harness sheath, and charging interface sealing have opened up new growth space for solid silicone rubber. Especially in the field of battery safety, solid silicone rubber is widely used for insulation and sealing of battery modules due to its flame retardancy and high temperature resistance, becoming an important part of the new energy vehicle safety system.

In the aerospace field, solid silicone rubber is responsible for sealing and protection in extreme environments. The high-temperature sealing rings around the aircraft engine, O-rings in the fuel system, piston seals in the hydraulic system, and window seals must all maintain reliable operation under temperature differences and severe vibrations ranging from minus 50 degrees Celsius to over 200 degrees Celsius. The wide temperature range performance and low compression permanent deformation characteristics of solid silicone rubber make it the preferred material for aviation seals. In the aerospace field, solid silicone rubber is also used for sealing and insulation of rocket engines, and its stability under extreme conditions has been verified through countless launch missions.
