Boat exhaust muffler

To manufacture their GRP (Glass Reinforced Polymer) products, silenceREvolution s.r.l. use special resins (R.I.Na. - Italian Naval Register - approved), which also guarantee excellent resistance to both chemical and galvanic corrosion (parasite currents), along with high structural resistance, even at high temperatures. The resins used prevent corrosion and ageing phenomena, feature excellent sound muffling properties and guarantee a higher melting point when compared with plastic silencers. In fact while a ÒwetÓ exhaust systems generally works at a temperature of around, 60°C, a silenceREvolution s.r.l. GRP silencer remains efficient even at temperatures in excess of 150° C, which are only reached if problems occur in the engine cooling system. This avoids the partial melting at temperatures of around 100° C that often occurs with plastic silencers, which may be more economical but are certainly less reliable. Our cylinder-shaped GRP silencers and connection pipes are made by winding continuous fibreglass filaments impregnated with a special resin around a spindle using a technique borrowed from the aerospace industry. The path and tension of the winding are generated and gauged using a computerised system (filament winding technology). silenceREvolution s.r.l., along with their most highly skilled experts in laminating techniques, can also manufacture GRP components that do not necessarily form part of the exhaust system but may be required to complete a particular installation. These are manufactured to Customer specifications.
