Engine, Generator, Mechanical Equipment Sound Absorbing and Insulation Foam

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Sound Absorption & Insulation: Designed to reduce noise pollution and thermal transfer in high-decibel environments, featuring polyurethane foam with a metallic reflective layer for enhanced acoustic dampening and heat resistance.
  • Dual-Layer Construction: Combines a smooth, beige top layer (50mm thickness) for optimal sound absorption with a rugged, blue-gray base layer for structural durability and thermal insulation.

Key features

  • 1. Advanced Material Technology with Dual-Layer Design

    • With a polyurethane foam core and a reflective metallic layer, you can achieve superior sound absorption while minimizing heat buildup. The top layer’s smooth, reflective surface reduces noise reverberation, while the rugged textured bottom layer enhances durability. Compared to single-layer acoustic foams, this design improves thermal insulation by up to 30%* in industrial environments.

  • 2. Optimized 50mm Thickness for Enhanced Acoustic Performance

    • With a 50mm thickness, you can effectively dampen high-frequency noises (e.g., engine hums) and low-frequency vibrations. This thickness outperforms standard 25mm panels by absorbing ~40% more sound energy in rigorous testing*. Ideal for machinery rooms and generator enclosures.

  • 3. Industrial-Grade Durability for Harsh Environments

    • The textured, blue-gray bottom layer is engineered to withstand mechanical stress and temperature fluctuations. Unlike flimsy single-layer foams, this product maintains structural integrity in high-vibration settings like factories or power plants, ensuring long-term reliability.

  • 4. Versatile Scenario Solutions for Commercial and Industrial Use

    • Designed for continuous operation in engines, generators, and mechanical equipment, this foam balances noise reduction with thermal management. It adapts to 24/7 industrial use, unlike office-grade panels that degrade under prolonged heat exposure*.

  • 5. Eco-Friendly Material Composition

    • Made from recyclable polyurethane foam, this product aligns with sustainability standards*. The non-toxic material ensures safety in enclosed spaces, meeting basic environmental regulations (subject to manufacturer confirmation).
