For its products in GRP, (Glass-Reinforced Plastics), uses special resins (R.I.Na. approved) that guarantee both optimum resistance to corrosion and excellent resistance to high temperatures. Silencers in GRP are made by the winding of continuous glass filament impregnated with resins around a spindle, using a technique borrowed from the aerospace sector. The path and tension of the winding are generated and gauged by a computer aided control system (“Filament winding technology”).
The special resins used avoid all corrosive phenomena and ageing process of materials. They are also characterized by excellent properties of noise reduction and ensure a higher melting point than plastic silencers. In fact, although a marine exhaust system generally “works” at not more than 60°C, a GRP silencer is efficient even at temperatures exceeding 150°C, avoiding partial melting already at around 100°C, as usually happens with silencers made of plastic, maybe cheaper, but certainly less reliable.
Naturally , with its workshops and its highly skilled experts in lamination techniques, is enterely at Customers disposal to produce GRP components that are not necessarily part of the exhaust system, but that may be needed to complete a particular arrangement and for this can be easily requested by the Customers and then made to their specifications.
