In industrial production and many special fields, high-temperature rubber sheets play an indispensable role. They are like tenacious guardians, standing firm in high-temperature environments to ensure the normal operation of various equipment and processes. So, just how high a temperature can high-temperature rubber sheets withstand?
Common high-temperature resistant rubber sheet materials include fluororubber, etc.
Conventional fluororubber sheets are generally used within the range of -15°C to 200°C, while high-temperature fluororubber sheets can operate within a range of -20°C to 230°C or even higher. This classification provides a more precise basis for selection for different industrial applications. For instance, in some chemical production processes with high temperature requirements, high-temperature fluororubber sheets can rely on their excellent heat resistance to function stably, ensuring that chemical reactions proceed smoothly within the appropriate temperature range and avoiding issues such as leakage and contamination caused by rubber sheet failure.

In addition to fluororubber sheets, there are also silicone rubber sheets, which can withstand temperatures up to 260°C and can operate in air within the range of -560°C to +260°C. This wide temperature tolerance range makes them stand out in various complex environments, whether it’s cold outdoor facilities or high-temperature indoor industrial settings, they can handle the conditions with ease.
From a broader perspective of industry applications, high-temperature resistant rubber sheets, as an important branch of special rubber products, are widely used in aerospace, automotive manufacturing, petrochemicals, power equipment, and other fields. In the aerospace industry, sealing components and thermal insulation pads around aircraft engines may use high-temperature resistant rubber sheets to withstand the high temperatures generated during flight; in automotive manufacturing, some protective pads and oil seals in the engine compartment rely on their heat resistance to ensure the reliability of vehicles during long-term driving or under high-temperature conditions; in the petrochemical industry, various reactors and pipelines’ sealing and protection cannot do without high-temperature resistant rubber sheets to prevent the leakage of high-temperature media and potential dangers.
It should be noted that although these rubber sheets have good heat resistance, in actual use, factors such as the working medium and pressure can also affect their temperature resistance limits. For example, for some high-temperature resistant rubber sheets with a working medium of water or air and a working temperature of 90°C to 140°C, when the medium or pressure conditions change, it may be necessary to re-evaluate their applicable temperature range.
