NANOFRABS “Halogen free flame retardant ABS nanocomposites”

The Restriction of Hazardous Substances (RoHS) and Waste Electric and Electronic Equipment (WEEE) directives discouraged the use of halogenated flame retardants in electric and electronic devices. For this reason, effective non halogenated alternatives have to be developed. NANOFRABS project aims, developing new halogen free flame retardant (HFFR) for ABS (acrylonitrile-butadiene-styrene) compounds, which are widely used in the electric appliances sector, with good impact and fire properties.

The focus is to develop a new more effective flame retardant for ABS, based on an intumescent formulation, by means of incorporation of nanofillers, enhancing both fire retardancy and mechanical properties. This will lead to the formation of a thermally and mechanically reinforced intumescent charred layer in event of fire as well as a mechanical reinforcement during the life of the product.

In order to reach these improvements, nanofillers will be combined with phosphorous-based flame retardants, either a) by Physical Combination of flame retardants and nanofillers in proper mixtures (PC), b) by Chemical Combination of nanofillers with flame retardants (CC) or c) by Physical Combination of Chemical functionalized lamellas and flame retardants (PCC) to be dispersed in the polymer by melt blending or melt reactive blending.
