How much high temperature can high-temperature resistant silica gel withstand?

The high-temperature resistance of silica gel is between 200 and 300 degrees Celsius.


High-temperature resistant silica gel is generally divided into zhi high temperature resistant solid silica gel and high-temperature resistant liquid silica gel. Therefore, liquid silica gel should be kept in a liquid state, so the amount of heat-resistant filler allowed to be added is less than that of solid silica gel. Therefore, under normal circumstances, Solid silica gel is more resistant to high temperatures and easier to do.


For solid silica gel, ordinary silica gel (not temperature resistant), its instantaneous temperature resistance can also reach 350oC, that is to say, it will be no problem if ordinary silica gel is placed in a high-temperature oven for one second.

This silicone flexible hose is an extremely resilient silicone, it displays excellent resistance to heat, weathering, ozone and a wide range of chemicals. It is impervious to UV lighting, non-toxic, chemically inert, even wall thickness retains its properties within -60~220 °C.  


Special high-temperature resistant silica gel can reach 350 degrees. High-temperature resistant silica gel is made of phenyl silicone rubber and fumed silica as the main raw materials, supplemented by high-temperature resistant additives, so that the product can withstand high temperatures up to 300-350 ℃, without secondary vulcanization, high tear strength, and resilience Good sex, not easy to yellow, and feel good;


It is not easy to be oxidized and degraded in ozone and radiation environment, and has good chemical stability; it has excellent water repellency, moisture resistance, earthquake resistance and physiological inertia. Uses of high-temperature-resistant silicone products: The product can be moulded and extruded to manufacture suction cups, electronic device trays, miscellaneous parts, pipes, oven sealing strips, high temperature resistant protective covers and other high-temperature resistant silicone products.
