100 YEARS • 1911 - 2011 Gaskets and Seals in Tenax® rubber fabric Our gaskets in cotton-fabric TENAX® do consist of fabric impregnated with elastomeric compounds through special manufacturing processes. Our pre-shaped rings with a rolled and wound structure are prepared, moulded and vulcanised in order to obtain the definitive profile. This special structure, combined with the design of profiles used for years in hydraulic systems, allows to produce gaskets with: - High elasticity; - Good mechanical resistance; - Good resistance to wear; - High resistance to pressure; - Resistance to mineral...
