Silicone rubber, as a polymer material with a unique structure, has molecular chains linked by silicon-oxygen bonds. This special chemical structure endows it with a natural foundation for heat resistance. Building upon this, 300℃ high-temperature resistant silicone rubber further enhances its heat resistance stability through formula optimization and process upgrades. Compared to ordinary silicone rubber, it features precise control over molecular chain crosslinking density and filler selection, enabling long-term use in continuous high-temperature environments of 300℃. It also effectively resists performance degradation caused by temperature fluctuations, preventing material aging, deformation, or failure due to high temperatures from affecting the normal operation of equipment.



In addition to its core heat resistance, this product series also possesses excellent mechanical properties, a key reason for its prowess in industrial applications. Even at high temperatures, key mechanical properties such as tensile strength and tear strength remain within reasonable ranges, without significant decrease due to rising temperatures. This dual advantage of "heat resistance + strong mechanical properties" allows it to withstand both high-temperature erosion and a certain degree of physical impact under mechanical stress, ensuring a long service life and effective performance under complex working conditions.Whether it's a molded seal or an extruded special pipeline, this characteristic enables long-term stable operation.

From a molding process perspective, the high-temperature resistant silicone rubber (300℃) series products have excellent processing adaptability and can be easily adapted to both compression molding and extrusion molding, two mainstream processes. Compression molding can meet the production needs of complex-shaped heat-resistant seals. Through mold shaping, products that meet the sealing requirements of different equipment can be precisely manufactured. Whether it is a flat seal, an irregularly shaped seal, or a dynamic seal scenario, a tight fit can be achieved, effectively preventing the leakage of high-temperature media.Extrusion molding is suitable for the mass production of long, strip-shaped, and tubular products such as heat-resistant extruded tubes. During production, the material flow is stable, resulting in uniform dimensions and a smooth surface in the formed tubes, meeting the needs of applications such as special fluid transmission and high-temperature gas flow. The flexible compatibility of these two molding processes allows this product series to cover a wider range of industrial applications, providing customized solutions for the high-temperature protection needs of different industries.

In industrial applications, the value of high-temperature resistant silicone rubber (300℃) has been fully demonstrated. In the automotive industry, it is widely used in components such as seals around the engine and protective sleeves for exhaust pipes. It withstands the high temperatures generated during engine operation, ensuring the sealing performance and heat dissipation of various systems within the engine compartment, indirectly improving the vehicle's operational stability and durability. In the electronics and electrical industries, it serves as an insulating and sealing material in high-temperature environments, used for the protection of electronic components and the encapsulation of high-temperature sensors, effectively isolating the effects of high temperatures on electronic equipment and ensuring the normal operation of circuit systems.

In high-end industrial fields such as aerospace and petrochemicals, the application of this product is indispensable. During flight, aerospace equipment generates extremely high temperatures due to engine exhaust and aerodynamic heating. Seals, pipelines, and other components made of high-temperature resistant silicone rubber can maintain stable performance under such extreme environments, ensuring the safe flight of the equipment. In petrochemical production, the sealing and protection of equipment such as high-temperature reactors and pipelines also rely on the support of high-temperature resistant silicone rubber. It can effectively resist the corrosion and erosion of high-temperature media, reduce the risk of leakage, and ensure the safe and orderly production process.

Furthermore, high-temperature resistant silicone rubber (300℃) is playing an increasingly important role in emerging industrial fields such as new energy and rail transportation. Battery pack cooling systems for new energy vehicles, high-temperature protection components for charging piles, and braking system seals for rail transportation equipment all place stringent requirements on the high-temperature resistance of materials. This series of products, with its stable performance, has become the preferred material in these fields, providing material support for the high-quality development of emerging industries.
