About this product

CFM for Closed Mold Process

3B Continuous Filament Mat is a non-woven mat made out of ECR glass filaments, consisting of continuous fibres randomly oriented in multiple layers. The glass fibre is bonded with a silane coupling agent and the layers held together with a suitable binder. The CFM products contain an insoluble binder compatible with both unfilled or filled unsaturated polyester, vinyl, ester, epoxy and polyurethane resin systems. The CM 4020 mat is ideally suited for injection moulding RTM and S-RIM processes. The CM 4020 mat has a high rigidity which helps to work with large CFM cuts without loosing fibres. The excellent mechanical properties provided by CM 4020 combined with the good electrical properties of the resins make the moulded parts attractive for applications like the electrical apparatus (high voltage), transportation and automotive industries, infrastructures equipments.

FEATURES - Insoluble binder - Low bundle tex

BENEFITS - Easy unrolling, cutting and handling of the mat without loosing the mat integrity even with large parts. - Good resistance to washing effect under injection pressure. - Improved mechanical properties of the laminate

PACKAGING The 3B Continuous Filament Mat is wound on a hard carton tube with an inside hole of 102 mm and an external diameter of 110 mm. A PE stretch film is wrapped around the roll to protect the material during handling and to help the slicing. All CFM rolls have 2 sides trimmed. The outside diameter of the roll is a standard of 55 cm. · For mat widths up to 210 mm : 6 vertical rolls per pallet · For mat widths above 210 mm : 6 horizontal rolls per pallet Each roll is identified by a roll label Each pallet is identified by minimum one pallet label including the date and the pallet weight. The load is fixed to the pallet with a stretch film. For more details on packaging, please contact the technical person.

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 fibre product should not undergo significant changes when stored for extended periods of time. It is also strongly recommended 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%).

Continuous Filament Mat 3B’s Continuous Filament Mat (CFM) is a non-woven mat made from 3B E-CR glass filaments, consisting of continuous fibres randomly orientated in multiple layers. The glass fibre is bonded with a silane coupling agent and the layers held together with a suitable binder. 3B offers two groups of CFM: powder mats emulsion mats Both provide end-users with different controls over rigidity, conformability, handling, wet-out and a range of tensile strengths. CFM is particularly suitable for compression moulded electrical and non-electrical laminates as well as for pultrusion and infusion or injection processes (e.g. RTM, S-RIM or Matched Die Moulding). CFM products contain an insoluble binder for unsaturated polyester, epoxy and polyurethane compatibility in unfilled or filled resin systems. In certain applications, 3B CFM also shows good compatibility with polyurethane foams.
