Basalt fiber needle felt is an advanced non-woven fabric made from fine basalt fibers, which are needled to form a highly porous and flexible mat. This material is known for its exceptional properties derived from basalt rock, a volcanic rock that offers robustness and durability. The process of creating basalt fiber needle felt involves mechanically interlocking the fibers without any binders, enhancing the integrity and mechanical strength of the felt.
Feature:
High Temperature Resistance:
Basalt fiber needle felt can withstand temperatures up to 800°C (1472°F), making it highly effective for thermal insulation in extreme heat environments.
Excellent Thermal Insulation:
Due to its porous structure, it has superb insulation properties, reducing heat transfer and saving energy in industrial processes and building applications.
Sound Absorption:
Its dense fibrous structure makes it an excellent material for acoustic insulation, effectively absorbing sound and reducing noise pollution.
Chemical and Corrosion Resistance:
Basalt fibers are inherently resistant to many chemicals, acids, alkalis, and salts, enhancing the durability of installations in corrosive environments.
Environmental Resistance:
It resists moisture, UV radiation, and microbial growth, which helps maintain its properties in various environmental conditions.
Eco-Friendliness:
Made from natural volcanic rock, basalt fiber needle felt is a sustainable material choice, with lower ecological impact compared to synthetic materials like fiberglass.
Application:
Industrial Insulation:
Widely used in industrial furnaces, boilers, and high-temperature pipe insulation to conserve energy and maintain process temperatures.
Fire Protection:
Its high-temperature resistance makes it ideal for fireproof linings, fire curtains, and other safety applications in buildings and transport vehicles.
Automotive Industry:
Used for heat and sound insulation within vehicles, particularly in engine compartments and exhaust systems where high temperatures are common.
Construction and Building:
Applied in HVAC systems for its thermal and acoustic insulation properties and in fireproofing applications due to its non-combustible nature.
Filtration:
The porous structure of basalt fiber needle felt makes it suitable for filtration applications, particularly in high-temperature or chemically aggressive environments.
Marine Applications:
Used in the construction and repair of marine vessels for insulation against both temperature and sound, contributing to safer and more comfortable environments onboard.
