Basalt Fiber Chopped Strands

Basalt fiber chopped strands are cut continuous filaments with diameters ranging from 5.5µm to 25µm and lengths from 3mm to 100mm. Coated with various coupling agents for different applications, they offer excellent dispersion and properties including high temperature stability, low temperature cracking resistance, fatigue resistance, and antistatic properties. These chopped strands find versatile applications such as enhancing asphalt in high-grade highways, reinforcing cement concrete structures and roads, serving as reinforced materials in resin composites, and creating high temperature corrosion-resistant filter media.

High Temperature Resistance

Basalt fiber has a higher melting point than glass fiber, making it more resistant to high temperatures. Basalt fiber can withstand temperatures up to 1000° C, while glass fiber typically has a lower temperature resistance of around 450-500° C. This makes basalt fiber ideal for applications where high-temperature resistance is critical, such as in the automotive and aerospace industries.

Strength and Stiffness

Basalt fiber is known for its excellent strength and stiffness properties, which are comparable to or even superior to those of glass fiber. Basalt fibers have a high tensile strength and modulus of elasticity, making them suitable for structural applications where high strength-to-weight ratio is important.

Chemical Resistance

Basalt fiber exhibits better resistance to acidic and alkaline environments compared to glass fiber. This characteristic makes basalt fiber suitable for applications where exposure to harsh chemicals is a concern, such as in marine and chemical processing industries.

Environmental Sustainability

Basalt fiber is considered a more environmentally friendly alternative to glass fiber. The production of basalt fiber requires less energy and resources compared to glass fiber manufacturing. Additionally, basalt fiber is non-toxic and recyclable, contributing to its eco-friendly profile.
