FAQ
10 things you may want to know about selecting friction fibres
Q1What role do mineral fibres play in friction materials?
Mineral fibres mainly act as reinforcement in friction materials: they improve the high-temperature stability, mechanical strength and fade resistance of the product, and support friction-property tuning for asbestos-free conversion. Boer BE-series fibres disperse easily and bond well with phenolic resin, and are suitable for disc brake pads, drum brake linings, railway brake shoes, clutch facings and engineering-machinery friction plates.
Q2How do I distinguish and select among the friction series models?
Common models include BE-SL05 (shot ≤1%), BE-GL3, BE-S06 (L/D ≥150), BE-G3, BE-F01, and the white fibres BE-B03 and BE-B07 (melting point above 1600℃). The choice depends on the formulation and process requirements; Boer provides selection advice and sampling support. Detailed parameters for each model are on its own detail page.
Q3What are the melting point and heat resistance of friction fibres?
Standard models have a melting point above 1000℃, and the white-fibre series (BE-B03, BE-B07) above 1600℃, suitable for high-temperature braking conditions. Specific values are subject to the batch test report.
Q4Why does shot content matter, and how does the wet process achieve dispersion?
Fibres with excessive shot (non-fibrous material) reduce the strength and surface quality of friction materials. Boer's wet process uses a water medium to eliminate the electrostatic attraction between fibre and shot, separating them by differences in gravity and resistance: for models such as BE-SL05 the shot content can be as low as ≤1% (>125 μm).
Q5How is the fibre surface treatment and resin bonding?
Boer's wet-process fibres receive a uniform surface treatment and bond well with phenolic resin, supporting even mixing and product consistency. L/D ratios range from ≥35 to ≥150 across the model range, selectable by formulation.
Q6Do friction fibres contain asbestos? What is the test basis?
Boer fibres are asbestos-free man-made mineral fibres. SGS report CANEC25025290506 (2025-10-22) shows all 6 asbestos types, including chrysotile, not detected (XRD/PLM, detection limit 0.1%).
Q7Are the products RoHS / SVHC compliant?
The products have passed RoHS 10-substance testing (report CANEC25025290502) and SVHC 250-substance testing (report CANEC25025290504), complying with applicable REACH requirements; originals can be requested for verification.
Q8Is an MSDS/SDS safety data sheet provided?
Yes. An SDS safety data sheet is provided (EECSSDS2605060802, prepared in accordance with REACH Annex II), and the batch test report is delivered with each shipment.
Q9What are the packaging and storage requirements?
Products are packed in moisture-proof laminated bags or eco-friendly paper bags, with custom packaging on request. Store in a dry, ventilated place away from moisture and caking, and keep away from open flame and strong oxidizers.
Q10How do I request a sample or selection support?
