Product Description

★ Product Features

1 High Tensile Strength

Basalt fiber boasts high tensile strength, typically ranging from 2.9 to 3.1 GPa. This strength is comparable to that of carbon fiber, yet it comes at a significantly lower cost. It demonstrates 15-25% higher tensile strength and modulus compared to regular E-glass.

2 High Elastic Modulus

With an elastic modulus ranging from 85-87 GPa, basalt fiber exhibits a high specific strength, notably three times that of steel, contributing to its effectiveness in reinforcement applications.

3 Temperature Resistance

Maintains structural integrity across an extended range, from -260°C up to +560°C. Ideal for high-temperature applications, thermal insulation, and fire protection, outperforming E-glass.

4 Corrosion Resistance

Robust resistance to chemical and environmental degradation. Its alkali resistance makes it particularly effective in alkaline environments such as concrete where steel might corrode.

5 Insulation Properties

Provides effective electrical and sound insulating properties, enhancing its versatility for use in electrical components and noise reduction applications.

6 Lightweight

Low density of 2.65 g/cm³ makes it significantly lighter than steel, contributing to crucial weight reductions in automotive and aerospace industries.

7 Durability

Renowned for high resistance to wear and tear, ensuring longevity. Exhibits good vibration resistance suitable for dynamic applications.

8 Non-Toxic & Safe

Filament diameter (10-20 μm) is above the respiratory limit. An inert material, certified non-carcinogenic by NTP, IARC, and OSHA, making it a safe replacement for asbestos.

⚙ Applications

? Frequently Asked Questions

What is Basalt Fiber?

Basalt fiber is a high-performance material made from extremely fine fibers of basalt, which is created by melting volcanic basalt rock. It offers a unique combination of high strength, temperature resistance, and durability.

How does Basalt Fiber compare to Glass Fiber (E-glass)?

Basalt fiber provides 15-25% higher tensile strength and modulus compared to regular E-glass. It also has a much broader working temperature range and superior alkali resistance, making it better for concrete reinforcement.

Is Basalt Fiber environmentally friendly?

Yes, it is a 100% natural, inert material made from volcanic rock. It is non-toxic, non-carcinogenic, and eco-friendly throughout its lifecycle.

What are the main benefits of using it in concrete?

When added to concrete, basalt fiber significantly enhances crack resistance, impact resistance, and overall durability, especially in harsh chemical or alkaline environments.

Can Basalt Fiber withstand high temperatures?

Absolutely. It maintains structural integrity from -260°C up to +560°C, which makes it ideal for fireproofing, thermal insulation, and high-heat industrial applications.

Is it a safe alternative to asbestos?

Yes, basalt fiber is a safe, non-hazardous alternative to asbestos. Its fiber diameter is large enough that it does not pose the respiratory risks associated with finer, hazardous fibers.
