Description

ArmaSound RD 240, also referred to as RD240, is a state-of-the-art, highly flexible, and hydrophobic open-cell acoustic insulation material. Crafted from NBR/PVC synthetic rubber elastomeric foam with a complex pore geometry, it delivers exceptional sound absorption and damping performance, even at reduced thicknesses. This makes it an ideal choice for applications where space is limited but high acoustic attenuation is critical. Gitco-sa.com, as an authorized Armacell distributor in Saudi Arabia and Bahrain, proudly offers this innovative solution for a range of acoustic insulation needs in industrial, OEM, and energy sectors. ArmaSound RD 240 is designed to operate across a broad temperature range from -20°C to 105°C, ensuring consistent performance in diverse environments. Its declared thermal conductivity is competitive, with λd​ at 0.043 W/(m·K) at 0°C and 0.045 W/(m·K) at 20°C, providing additional thermal insulation benefits. The material exhibits practical fire behavior, being self-extinguishing with a low burn rate. Its excellent sound absorption properties are demonstrated by its Weighted Sound Absorption Coefficient (αw​) and Noise Reduction Coefficient (NRC) values, which increase with thickness, achieving up to 0.75 (αw​) and 0.85 (NRC) for 50mm thickness. The complex pore structure ensures effective airborne sound absorption across a broad frequency range. Additionally, ArmaSound RD 240 is fiber-free, contributing to improved indoor air quality.
