China Basalt Fiber Needled Mat for Thermal insulation Product, Factories

Product Introduction

Basalt fiber needled felt, also known as basalt needle-punched nonwoven fabric, is a type of nonwoven material. It is produced by mechanically entangling basalt fibers using barbed needles. During the needle-punching process, the fibers are punched through a base fabric, interlocking them together to form a cohesive and stable structure without the use of binder.

Frequently Asked Questions

Q1: What is the maximum temperature Basalt Needle Mat can withstand? A: Basalt needled felt is designed for high-temperature environments and can typically withstand continuous temperatures up to 700°C (1292°F) and short-term exposure even higher.

Q2: Does basalt felt provide good sound insulation? A: Yes, its dense, interlocking fiber structure makes it an excellent material for acoustic absorption and vibration damping in automotive and industrial settings.

Q3: Is the material resistant to chemical corrosion? A: Absolutely. Basalt fibers are naturally resistant to acids, alkalis, and other harsh chemicals, making the felt ideal for industrial filtration and chemical processing.

Q4: Can the thickness of the basalt needle mat be customized? A: Yes, it can be produced in various thicknesses (commonly 6mm to 25mm) and different densities to meet specific insulation or reinforcement requirements.

Q5: Is basalt needled felt eco-friendly? A: Yes, basalt is a natural volcanic rock material. The production process is environmentally friendly compared to synthetic fibers, and the material is non-toxic and non-combustible.

Q6: In which industries is this material most commonly used? A: It is widely used in the automotive, aerospace, construction, and filtration industries for thermal protection, noise reduction, and structural reinforcement.
