Basalt needle felt for automobile soundproofing panels

Basalt fiber needle mat is a porous non-woven felt material with a certain thickness. Using basalt fibers with finer diameters, the short cut felt layer is reinforced and composite with the base fabric into a whole through needle punching machine combing, needle punching, or water needling processes, It is then processed by impregnation and drying to form a needle punched felt product. Numerous small holes are formed inside the fiber felt, giving the product extremely high insulation properties. At the same time, basalt fibers have high temperature resistance and excellent electrical insulation, and the products do not contain any adhesives. Can be widely used in fields such as sound insulation, sound absorption, shock absorption, flame retardancy, filtration, insulation, etc

 

1. High temperature resistance: basalt fiber has a high melting point, needle felt can work stably for a long time in a high temperature environment, usually the temperature range of resistance is between -260℃ and 700℃.
2. Corrosion resistance: excellent resistance to acids, alkalis and organic solvents and other chemicals, suitable for corrosive environments.
3. Excellent thermal insulation performance: low thermal conductivity makes it an excellent thermal insulation material, widely used in the field of thermal insulation.
4. Environmentally friendly and non-toxic: made of natural basalt ore, no harmful substances are released during the production process, which is a green and environmentally friendly material.
5. Good mechanical properties: high tensile strength and abrasion resistance, stable structure, long service life.
6. Sound-absorbing and noise reduction: the porous structure makes it has good sound-absorbing performance, which can be used for noise control.
7. Fireproof and flame retardant: non-combustible material, does not produce toxic fumes in case of fire, in line with fire safety requirements.
