Bio Soluble Fiber Board

Bio soluble fiber board (also known as AES Alkaline Earth Silicate) is a next-generation refractory material designed for industrial kilns, furnaces, and thermal processing equipment. Unlike traditional ceramic fiber, it dissolves harmlessly in body fluids. It makes it the go-to choice for engineers who need both safety and performance.

Why Bio Soluble Fiber Board Is Redefining Industrial Insulation?

As industries face increasing pressure to meet occupational health regulations and environmental compliance standards, bio soluble fiber board is emerging as the material of choice for high-temperature industrial insulation. Manufactured from high-purity alkaline earth silicate wool fibers, it dissolves naturally in body fluids and is classified as non-carcinogenic under EU and international safety standards, making it a responsible and future-proof alternative to traditional refractory ceramic fiber and aluminosilicate wool, without the bio-persistence risks that increasingly restrict their use in regulated markets.

Beyond its environmental and safety credentials, bio soluble fiber board delivers the rigid, lightweight thermal performance that demanding industrial applications require. Rated for operating temperatures above 800°C, it can be precision-cut, machined, and formed to fit complex furnace geometries with ease. Its consistent thermal performance across both continuous and intermittent heating cycles makes it a reliable long-term insulation solution. One that allows industries to meet their toughest process requirements and their most stringent sustainability commitments at the same time.

FAQs About Bio Soluble Fiber Board

Q: Is Bio-Soluble Fiber Board Safe? Does It Contain Rcf? Is It Classified as a Carcinogen?

A: Yes, it is completely safe. Our Bio-Soluble Fiber Board is made from calcium-magnesium-silicate (CMS) fibers, which have high solubility in human body fluids. Unlike traditional ceramic fiber (RCF), it is exempt from any carcinogenic classification under European Directive 97/69/EC (Note Q). It does not pose a health hazard during processing or installation.

Q: What Is The High-Temperature Shrinkage Of Your Bio-Soluble Board?

A: Our boards exhibit excellent thermal stability. The linear shrinkage is less than 3.5% after being exposed to 1200°C for 24 hours. This ensures the integrity of the furnace lining and prevents heat leaks or cracks over extended periods of industrial operation.

Q: Is The Board Easy To Cut And Machine? Does It Create Excessive Dust?

A: Our boards are manufactured with advanced organic and inorganic binders, giving them high flexural and compressive strength. They can be easily cut, drilled, or machined using standard hand tools with minimal dusting and clean edges, allowing for precise installation without crumbling.

Q: What Is The Thermal Conductivity Of Your Bio-Soluble Insulation Board?

A: It features extremely low thermal conductivity (typically ≤ 0.12 W/m·k at 600°C). Thanks to its low heat storage capacity, it significantly reduces energy consumption, speeds up furnace heat-up and cool-down cycles, and optimizes thermal efficiency for your equipment.

Q: Do You Have Ce Certification for Europe? Do You Provide SDS?

A: Absolutely. Our factory provides full SDS (Safety Data Sheets) and compliance certificates showing our products meet CE standards. We guarantee that our export shipments are 100% asbestos-free and eco-friendly, making custom clearance smooth and hassle-free.
