What are Hydrophobic Melamine Foam

Hydrophobic Melamine Foam (With self-adhesive backing & Without) is an enhanced version of melamine foam with exceptional water-resistance properties maintaining all other key attributes for sound deadening(after special treatment can achieve the hydrophobic ratio up to 99.1%).

Hydrophobic Melamine Foam is extremely lightweight (6-7 kg/m³) and flexible. The open cell surface allows sound waves to penetrate the foam and not reflect as an echo. Recommended for both acoustical and thermal insulation in aircraft, aerospace, marine, automotive, and architectural applications.
