Material Composition |
Constructed from high-density open-cell polyurethane foam or closed-cell elastomeric rubber. Foam absorbs airborne sound, while rubber blocks and dampens structural vibrations due to its mass and elasticity. |

Sound Dampening Properties |
Foam reduces echo and reverberation (30–50% noise reduction), ideal for mid-to-high frequencies. Rubber excels at blocking low-frequency noise and vibration, with up to 70% sound isolation in industrial settings. |

Thickness |
Available in a range of thicknesses from 6 mm (1/4 inch) to 50 mm (2 inches). Thicker sheets provide better low-frequency attenuation and thermal insulation. |

Temperature Resistance |
Rubber-based sheets can withstand -40°C to +130°C, while acoustic foams typically operate between -30°C and +100°C. Both materials resist deformation under thermal stress. |
