Properties and application
GRAFILIT® SL is a gasket material with excellent strength and creep resistance, chemical stability and a high tightness rate. Because of a stainless-steel insertion it is easier for handling and installation compared to the non-reinforced. GRAFILIT® SL is suitable for wide range of applications especially for higher operating pressures like in gas supply.
