Wholesale Fireproof & Corrosion-Resistant Basalt Fiber Yarn for Extreme Environments Pricelist, Suppliers

Our Continuous Basalt Fiber (CBF) yarn is volcanic rock transformed. Sourced from 100% natural basalt ore and processed at 1500°C, this golden-brown fiber bridges the gap between
glass and carbon fiber-offering superior thermal and mechanical properties at a competitive cost.

Product Description

Production Process
Product Features
High Strength Basalt fiber offers superior tensile strength, making it highly durable and resistant to wear and tear.
Heat Resistance It can withstand high temperatures, often up to 700°C, without degrading, making it suitable for extreme conditions.
Corrosion Resistance Unlike steel or glass fibers, basalt fiber is highly resistant to corrosion from chemicals, saltwater, and environmental factors.
Lightweight Despite its strength, basalt fiber is lightweight, making it ideal for use in composite materials where reducing weight is important.
Environmental Sustainability Made from natural volcanic rock, basalt fibers are eco-friendly and have a lower environmental impact compared to synthetic fibers like glass and carbon.

Frequently Asked Questions
What is the maximum temperature basalt fiber can withstand?
Basalt fiber is highly heat resistant and can typically withstand temperatures up to 700°C without significant degradation, and specialized treatments can extend this to 980°C.
Is basalt fiber better than glass fiber for chemical environments?
Yes, basalt fiber offers superior corrosion resistance against chemicals, acids, and alkalis, as well as saltwater, compared to standard glass fibers.
Is basalt fiber an eco-friendly material?
Absolutely. Basalt fiber is made from 100% natural volcanic rock through a single-component melting process, making it more sustainable than synthetic alternatives.
What are the common linear density options for basalt roving?
Typical linear densities range from 200 tex up to 2400 tex, allowing for versatility in various industrial and textile applications.
Can basalt fiber be used for electrical insulation?
Yes, it is an excellent substrate for electrical insulation boards and is commonly used in yarns and cords for insulating motors and electromagnetic wires.
How does the strength of basalt fiber compare to other materials?
Basalt fiber provides high tensile strength and high modulus, offering a lightweight yet incredibly durable alternative to steel and glass fiber in composite materials.
