✦ Synopsis

Dynamic sealing

TBA Sealing Materials Ltd was asked to develop a suitable asbestos-free gasket sheet for these pumps and the resultant material, Permanite SF 3500, is now in use with major split case pump manufacturers.

Permanite SF 3500 owes its success to a blend of rigid and fibrillating fibres, a high quality polymeric binder and a reinforcing fiUer system. Specially formulated surface layers were also needed and the finished product was able to overcome the disadvantages suffered by exfoliated graphite, general purpose aramid sheet and beater sheet.
