3B Continuous Filament Mat (CFM) is a non-woven mat made from Advantex™ filaments, consisting of continuous fibres randomly oriented in multiple layers. The glass fibre is bonded with silane coupling agent and the layers held together with a suitable binder.
3B offers two groups of CFM: powder mats and emulsion mats. Both groups 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 Molding). 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.

Mat EM 1002 with densities of 100, 150, 225 g/m2 is manufactured from chopped strands made of glass fibre bound together with an emulsion binder and drawn from E glass containing less than 1% of alkalies. The diameter of filament is 9 µm. The mat has a reduced strand linear density (tex) and the surface weight (density) comparing to the standard emulsion mat. It is very soft and it sets very well in a mould taking perfectly its very complicated shapes. It is characterised by a medium wet-out rate in a non-saturated polyester resin and by a good ability to remove air in the process of lamination.
Application
Emulsion bound mat EM 1002 with surface weights of 100 g/m2,150 g/m2 225 g/m2 is suitable for making laminates in a contact process. It is used with all types of non-saturated polyester resins for manufacturing products reinforced with glass fibre. It suites especially for manufacturing gel coated products as their reinforcement. It is also particularly recommended as the external layer of laminate in case of products with improved aesthetics of the surface.
