Even though it's pulp, it doesn't absorb water!?
Remarkably, we have developed a water-repellent sound-absorbing material made from pulp non-woven fabric that completely floats on water and even rises when pressed down with a finger. This sound-absorbing material, characterized by its almost non-existent water absorption, is made from a porous material called "airlaid based on pulp." It is ideal for areas where water absorption is not acceptable. Specifically, this includes sound-absorbing materials covering components that may condense or in environments with high humidity. Our manufacturing process uses pulp as the main raw material to create a porous structure with a high bulk and void ratio that absorbs sound. Among porous sound-absorbing materials, the surface of natural pulp not only has a special structure called microfibrils but also, due to its hollow structure, secures air layers within the fibers, which is expected to provide unique sound-absorbing effects different from other materials.

basic information
This is a water-repellent sound-absorbing material that shows almost no water absorption. - Excellent sound-absorbing properties unique to pulp fibers - Environmentally friendly pulp-based fibers - Does not absorb water even with a pulp base (effective in condensation areas) - Contains antibacterial and anti-mold agents - Sound insulation can also be added (rubber lamination) Comparison of sound absorption rates (1,000–6,300 Hz) with synthetic resin-based porous sound-absorbing materials: At the same thickness, it is about three times more effective compared to polyurethane foam! For equivalent sound absorption, it is almost half the thickness compared to felt and other companies' special non-woven fabrics! 【Product Specifications】 Surface layer: Polyester non-woven fabric Intermediate layer: Pulp fibers and polyester synthetic fibers Bottom layer: Polyester non-woven fabric Thickness: 5mm to 10mm (please consult for thicknesses other than those listed) Shape: Raw sheet 610mm wide × 800mm long (please consult for sheet length) Raw material roll: 600mm wide × 50m long (5mm product only) (Please consult for roll product width, roll length, slit width, and roll length) We have a catalog available.
