In the field of industrial manufacturing, material selection under high-temperature conditions has always been a core issue of concern for the industry.  Whether it's for sealing and protection of mechanical equipment or for the transportation needs of special pipelines, materials that can maintain stable performance in extreme high-temperature environments are crucial for ensuring production safety and improving product quality. In recent years, a special material capable of withstanding temperatures up to 350℃—high-temperature resistant silicone rubber—has gradually become a "mainstay" in industrial high-temperature applications, providing strong support for the upgrading and development of numerous manufacturing sectors.



High-temperature resistant silicone rubber, a special type within the silicone rubber family, boasts its exceptional heat resistance as its core advantage.  Compared to ordinary rubber materials, which tend to soften, deform, and age at temperatures above 150℃, this series of products can operate stably for extended periods at high temperatures of 350℃. Even under short-term, extremely high-temperature conditions, it maintains its basic structural integrity and performance stability, effectively addressing the industry pain point of material failure in high-temperature environments.This excellent heat resistance stems from its unique molecular structure—a chemical structure with silicon-oxygen bonds as the main chain. This structure gives the material exceptional thermal stability, allowing it to withstand the damage caused by high temperatures to the molecular chains and thus maintain good performance.

In addition to its core heat resistance advantage, high-temperature silicone rubber also possesses excellent mechanical properties, making it more practical in real-world applications.  It exhibits outstanding tensile strength, tear strength, and elastic recovery capabilities. When subjected to mechanical stress, it can effectively cushion impacts and absorb vibrations, and it is less prone to cracking or damage during long-term use. This dual advantage of "heat resistance + strong mechanical properties" allows high-temperature silicone rubber to adapt to complex industrial environments, resisting both high-temperature corrosion and various external forces during mechanical operation, significantly enhancing its suitability for a wide range of applications.

In terms of processing and molding, high-temperature resistant silicone rubber exhibits exceptional flexibility, easily adapting to both compression molding and extrusion molding, the two main processing methods, thus facilitating the production of different types of products. Compression molding allows for the precise replication of complex product structures, making it suitable for producing irregularly shaped heat-resistant seals, such as sealing rings and gaskets for high-temperature equipment; extrusion molding, on the other hand, excels in continuous production, efficiently manufacturing heat-resistant extruded tubes of various specifications to meet the mass production needs of high-temperature pipelines in industries such as chemical, electronics, and automotive.The flexible adaptation of these two molding methods not only reduces the processing difficulty for manufacturers but also allows for the customization of products in different shapes according to actual needs, further expanding their range of applications.

Currently, high-temperature resistant silicone rubber is widely used in various industrial fields. In the automotive industry, it is used to manufacture heat-resistant seals around engines, ensuring the sealing and safety of the engine during high-temperature operation; in the electronics and electrical field, it can be used as an insulating material and sealing component in high-temperature environments, improving the reliability of electronic equipment; in the chemical industry, heat-resistant extruded tubes are used to transport high-temperature corrosive media, reducing pipeline losses. As industrial manufacturing develops towards high-end and sophisticated directions, the demand for high-temperature materials will continue to grow, and the application prospects of high-temperature resistant silicone rubber will become even broader.
