Product Applications

The nickel foam tubes we custom-manufacture for clients are primarily used in the research of sound absorption silencers. These nickel foam tubes exhibit excellent sound absorption performance, effectively suppressing noise generated by mechanical ventilators and blowers.

Product Advantages
  • Good permeability. The permeability of water after complete blockage is 31.7%
  • Good noise reduction performance. Can reduce noise by 10-15 dB
  • High reliability. Can operate normally under a pressure of 40 MPa
