Thermogravimetric curve of 6311 phenolic resin

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

Abstract

This page presents the thermogravimetric (TG) curve of 6311 phenolic resin. It is a reference curve plot rather than a text article; the curve records the mass loss of the 6311 phenolic resin versus temperature under programmed heating, as a reference for the thermal behaviour of the resin binder used in friction materials.

FAQ

10 things you may want to know about Raw Materials

Q1What 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.

Q2What 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.

Q3What 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.

Q4Melting 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.

Q5Dispersibility 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.

Q6Does 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%).

Q7Is 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.

Q8Is 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.

Q9What 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.

Q10How can I select a product and contact Boer?

Call the national sales hotline 4006-0763-82 or email info@boerfibre.com. Boer provides selection advice, samples and batch test reports.
