Silentech is a lightweight, ester-based polyurethane (PU) fire-retardant (FR) foam, developed using advanced MEP (Microcellular Engineering Process) technology following extensive research and development. Its scientifically engineered composition and cell structure deliver exceptional Noise Reduction Coefficient (NRC) performance, even at reduced sheet thicknesses. Silentech effectively balances acoustic efficiency with compliance to stringent flammability standards, making it an ideal solution for high-performance sound insulation applications.
