Ludwigshafen, Germany - BASF is promoting the use of its melamine resin foam in water tanks, saying the energy-efficient potential of the foam is increasingly being used as external insulation for tanks made of stainless steel holding up to 500 litres of water.
BASF says a key factor for this application is the foam's low thermal conductivity of less than 0.035 W/(m*K) and the resulting excellent thermal insulation. So energy losses can be reduced in the production of hot process water.
The melamine foam may compete with polyurethane foam in insulating domestic hot water tanks. Many such tanks are supplied pre-insulated since the foam can be sprayed on, forming an integral part the tank construction.
BASF claims that melamine has other advantages over conventional insulation materials: resistance to temperatures of up to 240°C and flame retardance (in Germany: B1 according to DIN 4102).
