✦ Synopsis

Dynamic sealing

Material designed for high thermalmechanical stresses

A new material designed for high thermal-mechanical stresses has been introduced by Reinz-Dichtungs GmbH.

The newly developed material features a strongly expanded metal mesh reinforcement with a layer of asbestos-free soft material on both sides. The soft material contains no physiologically objectable substances and no colour pigments. Due to the expanded metal mesh reinforcement Reinz-AFM34 MetaU exhibits a number of characterisitics which include: • high sealability against gases • high tensile strength • high shear resistance • good stress resistance • chemically resistance • the material can cope with high unit loads The stainless steel reinforcement imparts high mechanical strength to the material and unlike non-reinforced materials permits AFM 34 Metall to cope with higher internal pressures and temperatures, for instance as is necessary for steam sealing. Flat gaskets of Reinz-AFM 34 MetaU can therefore be used in high pressure and temperature applications where, until now, graphite and spiral wound gaskets have been used.
