CM 1020

About this product

CFM for reinforced polyurethane foams

3B Continuous Filament Mat is a non-woven mat made out of E-CR glass filaments, consisting of continuous fibres randomly oriented in multiple layers. The glassfibre is bonded with a silane coupling agent and the layers held together with a suitable binder. The CM 1020 family products contain an insoluble 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 CM 1020 powder mat is ideally suited for polyurethane foaming processes for the reinforcement of foam panels. The excellent mechanical properties provided by 3B CFM combined with the good opening and the easy expansion of the CM 1020 mat during foam expansion make those reinforced R-PUF panels ideal for applications like thermal insulation of liquefied natural gas carrier and onshore storage.

FEATURES - Continuous fibres of E-CR glass - Silky touch - Very low binder content - Low integrity of the layers of the mat - Softness of the mat - Low bundle linear density (tex)

BENEFITS - Provide good mechanical properties in ambient and cool temperatures - Improve dimensional stability under temperature changes - High resistance to corrosion in water, salt water and alkali conditions - Easy unrolling and lay down, good adaptability to complex shapes - Fast and easy expansion during the foam generation process - Good distribution of the reinforcement over the thickness of the foam - Little resistance to resin flow for an easy and fast wet-through

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 or 118 mm depending on mat widths. 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 190 cm: 6 vertical rolls per pallet •For mat widths above 190 cm: 6 horizontal rolls per pallet For more details on the 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%. The product should remain in its original packaging, closed. 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.
