(Novapress® basic )
It is an asbestos-free gasket produced in Germany. It is composed of aramid fiber, nitrile rubber (NBR) and special fillers. After anti-adhesion treatment, it has good fluid compatibility and stress relaxation resistance. It can achieve good sealing effect on gases and other fluids, and the price is low. Suitable for public projects, chemical plants, steel plants, shipyards, refineries, power plants, pipeline engineering, and machine manufacturing.
