2 Pieces of 200×300×3.5mm Battery-Grade Nickel Foam - Sound Absorption and Filtration Material(40PPI)

grade nickel foam: shielding about 90DB electron wave through relatively thin thicknessPermeability: Homogeneous three-dimensional network structure, with the nction of filtration, gas, fluid, flow stability is super strong.Fire protection or not: withstand wind, rain, sunshine, is a class A non-combustible products.Sound absorber: directly facing the noise source, without any protective panels and other sound absorbing fillers.Electromagnetic shielding: Measures to reduce the field strength caused by certain sources.Technical Parameters:Ni purity: 99.8%Porosity: 95%, up to 98%Strength of extension>1MpaBore diameter: 0.2-0.6mmPPI: 110Thickness: 0.3-10mmAppearance: Silver grey metallic luster

• battery-grade nickel foam with a purity of 99.8%, ideal for super capacitors and various industrial applications.
• Uniform pore structure with 95% to 98% porosity, providing excellent permeability and efficient heat conduction for optimal performance.
• Ultra-lightweight devise, weighing only 1/4 of water, making it perfect for applications requiring minimal weight without compromising strength.
• Exceptional sound absorption properties, effectively reducing noise levels by directly facing sound sources without additional fillers.
• Durable and resistant to high temperatures (over 1100 degrees) and acid-alkali corrosion, suitable for a wide range of applications including catalyst carriers and filtration.
