SIGMA 500 is a multidirectional sealing material based on PTFE, filled with hollow glass microspheres and with the color code blue. SIGMA 500 is ideally suited for chemicals in the pH range from 0 - 14. A high compressibility guarantees an optimal seal even with non-parallel sealing surfaces and uneven flange surfaces.
