Silicone rubber sheet, a material that plays a significant role in modern industry, is a mystery to many. How does it stand out among other materials with its unique properties and shine in various fields?
Silicone rubber sheet is an industrial rubber sheet made mainly from silicone. Silicone, as its core component, endows the silicone rubber sheet with a series of outstanding and excellent properties. Chemically, silicone can be classified into two types: organic silicone and inorganic silicone. Inorganic silicone is a highly active adsorption material, which is produced through a series of complex processes including the reaction of sodium silicate and sulfuric acid, aging, and acid soaking. Organic silicone, 另一方面, has different synthesis routes and molecular structures. Both types lay the foundation for the diverse applications of silicone rubber sheets.
The performance advantages of silicone rubber sheets are truly remarkable.
It has excellent resistance to thermal aging in air, maintaining stable physical and chemical properties in both high and low-temperature environments. In an ozone environment, silicone rubber sheets also demonstrate strong resistance, effectively preventing performance degradation due to ozone erosion. Its insulation property is another highlight, allowing it to be safely used in electrical equipment to ensure stable current transmission and avoid electrical leakage and other safety hazards. 而且, silicone rubber sheets are resistant to fuel oil and lubricating oil, making them well-suited for applications in the automotive and mechanical industries where various oil media are involved. They can operate normally in air or oil media at temperatures ranging from -60°C to +250°C for long periods.

In the food industry, silicone rubber sheets have a wide range of critical applications.
Due to their non-toxic, 无味, and chemically stable nature, they are often used to make sealing components for food processing equipment, such as gaskets and washers. These sealing parts can effectively prevent food from coming into contact with external impurities and harmful substances, ensuring the hygiene and safety of food production. 此外, in high-temperature processing steps like baking and steaming, silicone rubber sheets can maintain the integrity of equipment seals with their high-temperature resistance, ensuring the smooth progress of food processing.
The demand for silicone rubber sheets in the mechanical industry is also high.
Various mechanical equipment require reliable sealing and shock-absorbing components to ensure efficient and stable operation. Silicone rubber sheets can be formed into different shapes and sizes of gaskets and seals, precisely installed in key parts of machinery to achieve sealing, leak prevention, 和减震. 例如, in hydraulic and pneumatic systems, silicone rubber sheet-made sealing parts can effectively prevent the leakage of liquids or gases, extend the service life of equipment, reduce maintenance costs, and their good flexibility can also adapt to the slight vibrations and deformations during the operation of mechanical equipment, ensuring consistent sealing performance.
The electronics and electrical industry is also an important application area for silicone rubber sheets.
With the increasing miniaturization and integration of electronic devices, there is a high demand for materials with excellent insulation, 耐热性, and stability. 硅胶橡胶板, with their outstanding insulation properties, are widely used in the packaging of electronic components and as insulating gaskets. In circuit board manufacturing, silicone rubber sheets can be used as the base material for laminates or insulating gaskets to prevent short circuits and improve the reliability and safety of circuit boards. 此外, in the heat dissipation design of electronic devices, silicone rubber sheets can also play a role. Their good thermal conductivity combined with heat resistance helps to evenly dissipate heat, ensuring the stable performance of electronic devices during long-term operation.
The rapid development of the automotive industry also relies on the support of silicone rubber sheets.
The engine compartment of a car is characterized by high temperatures and oil contamination. Silicone rubber sheets can withstand the erosion of fuel and lubricating oil and are widely used in automotive ignition wires, spark plug protectors, hoses for heating and cooling systems, muffler linings, battery terminals, 和其他组件. These silicone rubber products not only improve the performance of various car parts but also reduce maintenance costs and extend the service life of the vehicle. 此外, with the development of the trend towards lightweighting in automobiles, silicone rubber sheets also contribute to reducing the vehicle’s own weight. Under the premise of ensuring performance, they are lighter than some traditional materials, which helps to improve the fuel economy and handling performance of automobiles. In the chemical and light industry, the corrosion resistance and sealing properties of silicone rubber sheets make them ideal sealing materials for many chemical reaction vessels and pipeline systems. They can resist the erosion of various strong acids, strong alkalis and other corrosive chemicals, ensuring the airtightness of the chemical production process and preventing the leakage of chemicals from causing harm to the environment and personnel. In the metal and paint industries, silicone rubber sheets can be used as protective pads in the metal processing process to prevent the metal surface from being scratched or worn. 同时, in the paint spraying process, they can be used as backing plates or masking materials to ensure the uniformity and accuracy of the paint spraying and improve product quality.
