Melamine Foam

Melamine Foam is a flexible, open cell foam made from melamine resin, a thermoset polymer. Its characteristic feature is its three-dimensional network structure consisting of slender and thus easily shaped webs.

Properties include:

• Low Density (11 Kg/m³) - low weight factors
• Wide temperature Range up to 240°C [465°F]
• Excellent Acoustic Properties
• Excellent Thermal Insulation properties
• Constant Physical properties over a wide temperature range
• Flame Resistance
• Abrasiveness

Acoustic Properties

Melamine foam has excellent acoustical properties i.e. absorbing sound and is especially good where installation is concerned due to it s lightweight nature. The foam can be cut into plain sheets with or without self adhesive backing or it can be profiled for improved acoustical performance.

Chemical resistance

Thanks to Melamine Foam's highly cross-linked structure, it is resistant to all organic solvents. When it comes to acids and alkalis, the resistance has to be checked in concrete application cases since the temperature, the exposure time and the concentration all have a great deal of influence on the resistance of the foam to these media.

Fire behaviour

Melamine Foam's long-term heat resistance and outstanding fire behaviour can be attributed to the melamine resin component. The high nitrogen content of this resin accounts for the extremely high flame-resistance of the foam without the use of additional flame retardants. In case of a fire, Melamine Foam's thermoset nature ensures that it does not melt or create flaming droplets when exposed to flames. The foam merely chars under slight smoke generation and does not exhibit any afterglow. This is why Melamine Foam's is especially suitable for applications that call for increased fire-protection requirements.

Recent Developments: TG Grade

innovations in the formulation and processing of Melamine Foam were instrumental in making it suitable for thermoforming. The new TG grade is the first thermoset foam that can be shaped under heat. The impregnating step that used to be indispensable for thermoforming this material is now gone, vastly simplifying its processing. The first vehicle parts have already gone into serial production.

Melamine Foam can be thermally compressed until it takes a set, to create new foams with improved acoustical behaviour. As it is also open cell in nature, it can act as a filter medium.
