FAQ's of Basalt Fiber Yarn:

Q: How does Basalt Fiber Yarn's strength compare to other fiber materials?

A: Basalt Fiber Yarn exhibits a breaking strength of over 2000 MPa, which is significantly higher than standard E-glass fiber. This superior tensile strength ensures longevity and robust performance, especially in demanding industrial, construction, and composite applications.

Q: What are the primary benefits of using Basalt Fiber Yarn in industrial applications?

A: The main advantages include excellent resistance to fire (operating up to 700C, short term up to 960C), outstanding chemical and corrosion resistance against acids, alkalis, salts, and solvents, as well as exceptional electrical insulation. These properties ensure high safety and durability in various environments.

Q: Where can Basalt Fiber Yarn be applied?

A: Basalt Fiber Yarn is ideal for use in woven fabrics, reinforcements, composite production, fireproof materials, insulation, and construction. It is also well-suited for automotive and aerospace sectors where lightweight, high-performance materials are essential.

Q: What process is used to manufacture Basalt Fiber Yarn?

A: Basalt Fiber Yarn is produced by melting natural basalt rock at approximately 1450C, then extruding it into fine, continuous filaments with diameters ranging from 6 to 13m. These filaments are twisted or taken as direct roving, optionally finished with surface treatments, and then wound for shipment.

Q: Can the yarn's packaging and length be customized for specific requirements?

A: Yes, Basalt Fiber Yarn can be supplied in various lengths and packaged in cartons or pallets according to customer specifications. This flexibility ensures that the product meets diverse application and logistics needs.

Q: What surface treatment and coating options are available for Basalt Fiber Yarn?

A: Customers can select from untreated yarn or versions with sizing, and optional PTFE coatings or other custom finishes. These treatments enhance processing compatibility and end-use performance, depending on the fabrication methods and requirements.

Q: When is Basalt Fiber Yarn preferred over traditional glass fibers?

A: Basalt Fiber Yarn is chosen over traditional glass fibers when higher mechanical strength, better thermal stability, and increased resistance to aggressive chemicals and fire are critical, particularly in advanced composites, fireproof applications, and challenging environmental conditions.
