3B Continuous Filament Mat (CFM) 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 are held together with a suitable binder. The M8630 family products contain an insoluble binder compatible with a large range of thermoset matrices like both unfilled or filled unsaturated polyester, vinyl ester, epoxy and polyurethane resin systems. The M8630 mat is ideally suited for matched metal die moulding, RTM and S-RIM processes for moulding flat, large and heavy panels or non-complex parts. The excellent mechanical properties provided by 3B CFM combined with the good electrical properties of the resins make the moulded parts attractive for applications like electrical apparatus (high voltage), transportation industries and infrastructure equipment.

FEATURES AND BENEFITS
Integrity and rigidity of the mat

• -Designed for large panel production

• -Can be unrolled, cut and conveyed to the mould without loosing mat integrity, even with large parts

• -Easy to tailor to shape design without causing wrinkes or leaving resin-rich radii, which may cause cracking

• -Resist to relocation in the mould under pressure and resin flow (wash resistance)

Porosity

• -Little resistance to resin flow for an easy and fast wet-through, even with filled resin

Advantex® glass is a boron-free glass and presents significantly improved corrosion resistance across a wide range of aggressive environments. Advantex® glass is an E-CR glass in accordance with ASTM D578 and ISO 2078. This translates into important benefits for end-users over traditional E glass: longer service life, larger safety coefficients for the same design, and material savings. Traditional E-glass includes boron and often contains added fluorides. By using new manufacturing technology to eliminate these components from the glass composition, Advantex® glass has become a benchmark for integrated pollution prevention and the highest energy efficiency, all in an optimized process. 3B measures its efforts and works continually to minimize its impact on the environment and to set new standards within the global fibreglass industry. This is our commitment.
