PU Sound Absorbing Sponge

PU sound absorbing foam, also known as egg crate foam or corrugated acoustic foam, which is a widely used sound-absorbing material made of flexible polyurethane (PU) foam with a wave surface structure.

Features & Advantages

  • Excellent sound absorption: The open-cell foam structure and wave-shaped surface effectively trap sound waves, reduce reverberation and echo, and improve acoustic clarity. It performs well in absorbing medium and high-frequency noise.
  • Lightweight & flexible: Soft, elastic, easy to cut, compress and install, with good resilience and not easy to deform.
  • Heat insulation & shock absorption: Provides basic thermal insulation and minor cushioning performance.
  • Safe & eco-friendly: Low odor, non-toxic, environmentally friendly, and available with flame-retardant certification for public and commercial use.
