Foam spring constant
WebFoamTech melamine foam retains it properties over a wide temperature range. It keeps its flexibility even at -200 °C and is also suitable for application tem- peratures up to 240 °C. This enables a broad variety of applications, such as insulation of liquefied natural gas (LNG) tanks or soundproofing of engine compartments. Resistance to chemicals
