PU wave cotton

It is widely used in central air-conditioning ducts, silencer systems, indoor sound insulation and noise reduction of buildings, and noise reduction of other equipment.

The wave sound-absorbing sponge is specially processed to form a unique concave-convex curved surface structure, which minimizes noise transmission through diffuse reflection, combining the original closed-cell sound insulation and heat preservation with the surface open-hole sound absorption functions.

As thermal insulation material inside air ducts, it can achieve the dual functions of thermal insulation and noise reduction.
