中文/EN

Basalt New Materials

In the new materials industry, Ark is committed to advancing the development of high-performance composite materials based on basalt mineral fibers. The company engages in the research and development, production, demonstration applications, widespread promotion, and commercial operations of inorganic mineral fiber composites, while building a full‑chain processing base for high‑end composite materials centered on inorganic mineral fibers.

Technical Team

At present, the company has developed more than 20 types of high-performance basalt fiber‑reinforced composite products, including fabrics, boards, boxes, rebars, cables, profiles, rock bolts, and meshes, covering such diverse fields as transportation, municipal engineering, water conservancy, environmental protection, new energy, marine engineering, and national defense. The company’s flagship products comprise continuous basalt fiber yarns, chopped basalt fibers, composite rebars, rock bolts, geogrids, photovoltaic mounting brackets, cable trays, pipelines, and a wide range of other composite‑material components.

Performance Advantages

9 big

Performance Advantages

Excellent insulation properties

Good insulating materials can withstand high voltages without being damaged.

Good thermal performance

Low thermal conductivity

Excellent processability

Energy-efficient materials

Good corrosion resistance

It exhibits good resistance to acids, bases, salts, as well as oils and solvents.

Good dimensional stability

The linear thermal expansion coefficient is 7.3 × 10⁻⁶/°C, which is lower than that of steel and aluminum alloys.

Highly customizable

Select a variety of materials to meet the specific requirements of different products.

Secondary processing

Secondary processing does not affect the product’s corrosion resistance or pressure-bearing capacity.

Good shock-absorbing performance

The elastic modulus is 24,000, and it exhibits shock-absorbing and seismic-resistant properties.

Good weather resistance

It can live for up to 25 years.
