3B Fibreglass M 8643

3B Fiberglass M 8643 is a non-woven mat made out of E-CR glass filaments, consisting of continuous fibers randomly oriented in multiple layers. The glass fiber is bonded with a silane coupling agent and the layers held toge-ther with a suitable binder. The M 8643 products contain an inso-luble binder compatible with a large range of thermoset matrices like both unfilled or filled unsaturated polyester (UP), vinyl ester (VE), epoxy (EP) and polyurethane (PU) resin systems. The M 8643 emulsion mat is ideally suited for pultrusion processes for wide, long and heavy parts but also for narrow and complex profiles. The excellent mechanical properties provided by 3B CFM combined with the good electrical properties of the resins (i.e. UP) make the pultruded parts attractive for the electrical apparatus (high voltage), trans-portation industries and infrastructure equipments.

Packaging & Availability

Packaging
  • The 3B Continuous Filament Mat is wound on a hard carton tube with an inside hole of 102 mm and an external dia-meter of 110 mm. A PE stretch film is wrapped around the roll to protect the material during handling and to help the slicing. All 3B CFM rolls have 2 sides trimmed.The outside diameter of the roll is a standard of 55 cm
  • For mat widths up to 210 cm : 6 vertical rolls per pallet·
  • For mat widths above 210 cm : 6 horizontal rolls per pallet

Storage & Handling

Storage

Storage in a cool and dry warehouse into the original packaging is formally recommended. More precisely ideal storage conditions are a temperature between 15°C and 35°C and a relative humidity comprised between 35% and 75%. If these conditions are maintained, the glass fiber product should not undergo significant changes when stored for extended periods of time. It is also strongly recom-mended to condition it in the workshop for at least 24 hours before use to prevent condensation.For an optimal processing we recommend to use the product in ambient conditions (20°C-23°C and a relative humidity of 60%-65%).
