Mineral fiber is a fiber obtained from mineral rocks with a fibrous structure, and its main components are various oxides. Alfa Chemistry offers a range of mineral fiber products to meet your specific needs.
Introduction
Mineral fiber is made of specially selected mineral rocks, which are pre-treated, melted at 1500 ℃, extracted and drawn, and then treated with special surface treatment. The softening point of mineral fiber is about 1200 ℃, the fiber surface is smooth and complete, and it is safe to use and will not cause harm to the human body.

Characteristics
- Mineral fibers have high tensile strength and are resistant to chemicals and biological degradation.
- Mineral fibers are non-combustible and do not provide a fuel source for fires.
- Mineral fibers are lightweight, flexible, and have a high resistance to heat and thermal shock.
- Mineral fibers have excellent insulation properties.
- Mineral fibers are non-toxic and do not pose a health risk when handled properly. However, certain types of mineral fibers such as asbestos can be harmful if inhaled or ingested.
- Mineral fibers have high durability and can withstand harsh environmental conditions, making them suitable for outdoor applications.
- Mineral fibers have low thermal conductivity, which helps to reduce energy loss and improve energy efficiency.
Applications
Mineral fibers are versatile materials with a wide range of applications due to their excellent performance. Some key applications are as follows:
- Insulation materials. Mineral fibers are commonly used as insulation materials in buildings, pipes, and appliances. They provide thermal insulation and help to reduce energy costs by keeping heat in during the winter and out during the summer.
- Acoustic panels. Mineral fibers are used in the production of acoustic panels for soundproofing applications. They absorb sound waves and reduce noise levels, making them ideal for use in recording studios, theaters, and noisy industrial environments.
- Fireproofing materials. Mineral fibers have excellent fire-retardant properties, which make them suitable for use in fireproofing materials such as fire blankets, fire doors, and fire-resistant coatings for buildings.
- Filtration systems. Mineral fibers are used in the production of air and liquid filtration systems. They act as a barrier to capture dust, dirt, and other particles, improving indoor air quality and protecting equipment from damage.
- Reinforcement materials. Mineral fibers are added to composites and building materials such as concrete, plaster, and asphalt to improve their strength, durability, and resistance to wear and tear.
- Textiles. Mineral fibers are used in textile manufacturing to produce fabrics with heat resistance, fire retardancy, and insulation properties. They are also used in protective clothing for firefighters, welders, and industrial workers.
