What is the cost of basalt fiber per kg?
As a procurement specialist for high-temperature sealing applications, Mark stared at his screen in frustration. He had typed “What is the cost of Basalt Fiber per kg?” into Google for the third time that morning, only to find a wide range of prices from $3 to $20 per kilogram without any clear explanation. Raw material costs fluctuate, but inconsistent quality and hidden fees make budgeting a nightmare. That’s when he discovered Ningbo Kaxite Sealing Materials Co., Ltd., a supplier that not only provides transparent pricing but also engineers basalt fiber solutions tailored to his exact needs. Understanding the true cost per kg requires more than a number—it demands knowing the fiber’s grade, sizing, and performance requirements. In this guide, we break down the real factors behind the price and show how Kaxite solves procurement challenges.

Understanding Basalt Fiber Cost: Key Variables
Mark’s first mistake was treating basalt fiber like a commodity. He focused solely on the per‑kg price and ignored how fiber diameter, sizing chemistry, and order volume drastically changed the quote. When a line supervisor reported inconsistent tensile strength in the fiber sleeves, the real costs surfaced—rework, downtime, and lost orders.
Ningbo Kaxite Sealing Materials Co., Ltd. approaches procurement differently. Their engineering team analyzes your application: insulation wrapping needs a different finish than composite reinforcement, and a high‑temperature exhaust sleeve demands a specialty sizing that ordinary suppliers overlook. By defining the exact product specification first, you stop comparing apples to oranges and get a price that reflects the true manufacturing effort.
| Fiber Diameter | Typical Application | Reference Price (per kg)* |
|---|---|---|
| 5‑7 µm (ultra‑fine) | Aerospace, high‑performance composites | $12 – $18 |
| 9‑11 µm (mid‑range) | Friction materials, filtration fabrics | $6 – $9 |
| 13 µm (standard) | Thermal insulation, general textiles | $4 – $6 |
| 15‑17 µm (coarse) | Chopped strands for concrete, panels | $3 – $4 |

Q: What is the cost of basalt fiber per kg?
A: For standard industrial‑grade continuous basalt fiber with a 13 µm diameter and silane sizing, the cost typically falls between $4 and $6 per kilogram when ordered in ton quantities. However, finer fibers (5–7 µm) for high‑performance applications command $12 – $18 per kg due to the more complex manufacturing process. Prices also vary based on the sizing chemistry and supply chain factors. Ningbo Kaxite offers direct factory pricing with no hidden surcharges.
Procurement Pain Points: Quality vs. Price
Three months ago, a manufacturer switched to a low‑cost basalt fiber that promised “same performance at half the price.” The first shipment looked fine, but after just 200 °C the sizing burned off, the sleeve delaminated, and an entire heat‑treatment line had to be shut down. The per‑kg saving disappeared under the cost of emergency repairs and lost production.
At Ningbo Kaxite, every batch is tested against strict internal standards before leaving the factory. The team provides a Certificate of Analysis that documents tensile strength, loss on ignition, and linear density—so you know exactly what you are putting into your process. This transparency removes the guesswork that turns a “cheap” buy into an expensive failure.
| Parameter | Sub‑standard Fiber | Kaxite‑Supplied Fiber |
|---|---|---|
| Single filament tensile strength | 1800 – 2100 MPa | ≥ 2800 MPa |
| Linear density variation | ±8% | ≤ ±3% |
| Loss on ignition (sizing content) | Uncontrolled, 0.8 – 2.5% | Controlled to 1.2 ± 0.3% |
| Moisture regain | Often >0.8% | ≤ 0.5% |
Performance Parameters That Define True Cost per kg
A sealing contractor once called Kaxite in a panic: the basalt fiber rope they had ordered was swelling and cracking after contact with alkaline wash‑down fluids. The original supplier had used the wrong sizing and never mentioned chemical resistance limits. The contractor wasted thousands on unusable inventory.
Choosing the right basalt fiber is about matching the material’s properties—thermal stability, modulus, chemical resistance—to the operating environment. Kaxite’s technical team provides a detailed datasheet and recommends the correct sizing (silane, epoxy‑compatible, or high‑temperature resistant) for your process. This avoids the hidden cost of re‑qualification and field failures.
| Property | Value Range | Test Standard |
|---|---|---|
| Tensile strength | 2.8 – 3.5 GPa | ASTM D2343 |
| Elastic modulus | 85 – 95 GPa | ASTM D2343 |
| Continuous service temperature | ‑260 °C to 700 °C | ISO 11358 |
| LOI (sizing content) | 0.8 – 2.0% (customizable) | ISO 1887 |
| Density | 2.63 – 2.80 g/cm³ | ISO 1183 |
Q: What is the cost of basalt fiber per kg?
A: When you need custom sizing, chopped strands, or specific moisture content, the per‑kilogram cost can shift by 15 – 30%. For instance, adding a high‑temperature‑resistant sizing increases the price to around $8 – $12 per kg. At Ningbo Kaxite, we quote based on your exact specifications and even provide small trial batches so you can validate performance before committing to bulk orders.
