Over the years, Regal Rubber has become increasingly involved with the rubber lining of offshore and marine products.

Rubber Coating of Marine Sheaves

The Puretic power block is a special kind of mechanised winch used to haul nets on fishing vessels. The power block is a large powered aluminium pulley incorporating a 'V' or 'W' shaped sheave which is protected with a specially designed neoprene rubber coating. At one time many men were needed for the back-breaking work of hauling a purse seine manually however the same work can now be carried out with fewer men using a power block.[1]

The Puretic power block revolutionized the technology of hauling fishing nets, particularly purse seine nets.
