What is mineral fibre?

Per GB/T 4132-1996, man-made mineral fibres are the general term for inorganic fibres made from rock, slag, glass, metal oxides or porcelain clay. Boer products are made mainly from natural rocks such as diabase, basalt and dolomite, processed by melting, wet-process purification and surface treatment.

What does Boer's wet process mean?

Raw materials are melted in a cupola furnace and fibreised by a four-roll centrifugal spinner. Fibres are separated from shot in the settling chamber, then collected by hub collectors, purified, dried and packaged. The water medium eliminates electrostatic attraction between fibres and shot, and separates them by their different gravity and drag in motion.

What is shot content and how is it controlled?

Shot refers to non-fibrous material in the fibre (usually counted above 125 μm). Boer separates fibre from shot in the settling chamber through the wet process; some models control non-fibrous content below 1%. Specific values are subject to the batch test report.

Melting point and heat resistance?

Standard models have a melting point above 1000 ℃; the white-fibre series (e.g. BE-B03, BE-B07, BE-C08) has a melting point above 1600 ℃. Specific values are subject to the batch test report.

Dispersibility and resin bonding?

The wet process gives a more uniform surface treatment; the fibre is hydrophilic and easy to disperse, bonding well with phenolic resin, and is suitable for friction and sealing material formulations.

Does Boer fibre contain asbestos?

No. Boer products are asbestos-free man-made mineral fibres and have passed SGS asbestos testing (report CANEC25025290506, 2025-10-22); all 6 asbestos types, including chrysotile, were not detected (XRD/PLM, detection limit 0.1%).

Is Boer fibre RoHS/SVHC compliant?

Yes. Products have passed RoHS 10-substance testing (CANEC25025290502) and SVHC 250-substance testing (CANEC25025290504), complying with applicable REACH requirements.

Is an MSDS/SDS available?

Yes. Boer can provide MSDS/SDS prepared in accordance with REACH Annex II (e.g. EECSSDS2605060802), and the batch test report is delivered with each shipment.

What are the packaging and storage requirements?

Normally moisture-proof laminated bags or eco-friendly paper bags, with custom packaging on request. Store in a dry, ventilated place away from moisture, open flame and strong oxidizers.

High-performance carbon-fibre composites in China

Category Raw Materials Published 2026-03-31 Source www.boerfibre.com

Abstract

Carbon fibre is the general term for fibres with over 90% carbon content, combining carbon's light weight, heat and thermal-shock resistance, chemical corrosion resistance and conductivity with fibre flexibility and mechanical performance; it can withstand high temperature without losing strength and, under oxygen-free conditions, up to 2000 ℃, suiting reinforced composites, ablative and insulating materials.

The article describes China's carbon-fibre industrialisation: supported under national programmes and the 12th Five-Year new-materials plan, thousand-tonne lines have been built, companies such as Weihai Tuozhan, Jiangsu Hengshen and Zhongfu Shenying have emerged, and capacity has reached over 20,000 tonnes. Demand grew from 2995.1 t in 2008 to 4240.6 t in 2010 (+17.4%) and 6000 t in 2012 (+18.6%). The article notes domestic product is mainly T300-level 3k/12k, while T700 is in engineering research and T800/MJ series under development, with a cost gap versus imports. Main applications are aerospace/defence and sports equipment, with growing use in pressure vessels, wind power, friction materials, automotive and new energy.
