New Nepol long, glass fibre reinforced polypropylene concentrate from Borealis

Borealis A/S : 11 May, 2006  (New Product)
There is a growing trend to use dilution technology as a cost effective route for technically demanding injection moulded applications. This technology reduces the quantity of compounded material used by diluting a concentrated long, glass fibre compound ('concentrate') with reactor polypropylene at the injection moulding stage.
To meet the needs of customers making this transition from conventional moulding, Borealis has launched Nepol GB600HP-9502.

Nepol GB600HP-9502 is designed for use in combination with specially developed dilution PP BJ100HP reactor compound. These can be injection moulded on a standard machine fitted with metering and mixing equipment. Through appropriate dosing of the polymers, a glass fibre content in the range of 20-40% can be achieved in the final part.

This product combination includes an additive package with components for long-term temperature resistance and processing stability, as well as for the optimum coupling of polymer and glass fibre to ensure high stiffness and impact strength in the moulded part.

Initially, the Nepol GB600HP-9502 and BJ100HP development is directed towards serving the automotive industry where dilution technology is widely used in the injection moulding of load bearing parts.

Typically these include black structural components such as carriers for front-ends, instrument panels and for side door modules. Especially when the combination of load bearing and water or humidity resistance is required, these materials can replace metal and save weight.

Importantly, for OEMs and Tier 1 suppliers, Borealis also delivers a comprehensive range of the PP materials used for the components that build on these structures to form complete units, such as for bumpers that integrate with front-end carriers.

The combination of Nepol GB600HP-9502 and BJ100HP in the dilution process offers very good dimensional stability, very low moisture absorption and high creep resistance even at elevated temperatures.

The product combination with these properties provides an ideal solution for a broad range of tough engineering applications.
