Gasket→Non-Asbestos Sheet Gasket
Non-Asbestos Sheet Gasket ZW#8800
This Germany-made gasket has balanced raw material combination, consisting of high-grade Aramid fibers, special fillers and NBR rubber (Nitrile Butadiene Rubber) binder with A310 anti-stick coating. It demonstrates good resistance to media, standard permeability to gas, good stress relaxation, favorable cost-performance in a wide range of applications such as utility or sanitary applications (gas and water supply), chemical plant, steel works, ship building, oil refinery, power plant, pipeline construction, plant and machine building industry.
