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.
