Melatech Acoustic Foam
Melatech Acoustic Foam is an open cell, melamine foam. It is lightweight, flexible, easy to handle and does not flame or emit toxic fumes when exposed to heat. It is designed for use in thermal and acoustic insulation applications. Melatech is available in sheets, die-cut to size and shape or profiled. It can be faced one side or totally enclosed in a wide range of materials to meet specific performance requirements. Melatech can be supplied with a self-adhesive backing if required.
Melatech acoustic foam is used extensively in heating, ventilation and air conditioning equipment, railway rolling stock, wall and ceiling panels, acoustic enclosures, recording studios, theatres, cinema auditoria and other leisure complexes. It is used as case linings, splitter and louvre infills in the power generation industry and in a variety of automotive applications.
