It is used in temperatures between -60°C and 200°C. It has an intermittent capacity to endure temperatures up to 250°C. It is primarily used in crank seals. It has high elasticity, as well as high air and ozone resistance. It is not recommended for use in fuels, oils with EP additives, and applications that require high mechanical properties.

     Silicone was developed during World War II for commercial purposes, in order to meet the high heat resistance needs desired in military applications. In the following years, studies on silicone continued, and the tensile strength, flexing, sagging and resistance properties of the material were constantly improved. Resistance to the wide temperature ranges and the related physical properties, which were improved specifically, rendered silicon superior to synthetic polymers.

     Silicone rubbers were derived from inorganic silica, commonly known as sand. Silicon rubber was obtained as a result of the treatment of sand, the basis of silicone, with oxygen atoms. This basic process is the same as the processes in heat-resistant quartz and glass. Consequently, silicone rubbers not only provide excellent resistance to low and high temperatures, but are also resistant to ozone, weather, UV rays, acids, bases, oils, fluids and food products.

    However, top quality solvent-free silicone must be used to achieve these properties. In addition, after the application, it should be left to rest for at least 3 days before coming into contact with food.
