Micaseal Suniflex – Premium heat resistance for demanding conditions
Micaseal Suniflex is mica-based gasket material designed for environments that require high heat resistance and versatile chemical resistance. It has plenty of use cases in power plants, combustion engines, exhaust systems and gas scrubbers.
Mica-based materials work especially well in places where graphite proves inadequate. Graphite-based materials start to slowly burn in temperatures over 450 °C and the burning intensifies the higher the temperature rises. Mica can withstand temperatures of over 900 °C.
The new material is available in three 316L steel reinforced thicknesses: 1.3 mm, 2 mm and 3 mm. Metal eyelets can be used to improve the material’s sealing qualities and leaking pressure even further.
The material has fulfilled our rigorous quality requirements and is available immediately. Micaseal Suniflex is well-suited for different gasket geometries, and we are happy to help you in designing sealing solutions for even the most demanding conditions.
