STC Trade Sustainable innovations for shipbuilding & industry
In the shipping industry, seawater is used to cool engines of ships and yachts. The seawater is filtered from seaweed, fish, shells and pollution like plastic. Most filters are made of metal. Metal is highly susceptible to corrosion (these filters last only 1 – 5 years in salt water), very heavy and gives a bad footprint. The solution is filters made of HDPE and glass fiber reinforced plastic (GRE or GRVE). Both HDPE and GRP are extremely suitable for corrosion by seawater and external influences.
