Borealis and Borouge, leading providers of innovative, value-creating plastics solutions, will showcase their new Daplen grade at the VDI Mannheim fair taking place this month.

The latest Daplen grade was developed in cooperation with BMW for the front bumper of the electric sports car BMW i8 and is a recent and specific example of how Borealis and Borouge innovations can play a role in facilitating systematic lightweight construction in the automotive industry.

Primerless painting systems address the need for greater economy and sustainability in automotive exterior applications by reducing cycle time and system costs. For the production of its revolutionary top-of-range electric sports car BMW i8, BMW required a lightweight bumper material that delivered on several key aspects in processability and manufacturing. Developed in close partnership with BMW for use in the front bumper of the BMW i8, the new grade Daplen EE112AE shows how Borealis and Borouge deliver expertise along the entire product and application development chain in order to facilitate primerless paint systems for exterior plastic applications which fulfil the most demanding design and performance criteria.

The new-generation Daplen EE112AE is a 12 per cent mineral-filled elastomer modified polypropylene (PP) compound. It fulfils BMW’s extremely stringent paint adhesion quality requirements for primerless paint systems in their in-house manufacturing operation. Commercially launched in the last quarter of 2014, this grade provides easy processability for low production scrap rate as well as reduced density.

Most crucially for this electric sports car, the good impact/stiffness balance provided by Daplen EE112AE enables a low part weight.

Another innovative material solution, Fibremod GB215HP, is being used in the BMW i8 IP carrier. A 20 per cent long glass fibre reinforced PP grade, Fibremod GB215HP provides excellent strength, high stiffness and outstanding energy absorption in high speed deformation, thus ideally fulfilling today’s stringent crash and impact requirements. Although not a new grade, Fibremod GB215HP helps support BMW’s own integral foaming injection moulding process, resulting in low warpage and excellent dimensional stability.

The start-up of expanded production facilities in Itatiba, near Sao Paulo, Brazil, at the end of 2014 means that Borealis has now passed another milestone on the way to continued expansion of global supply capabilities. As of the end of last year, the mechanical completion of the Itatiba expansion had been completed, allowing for the testing of grades and start-up of production.

“We are pleased to be able to use VDI Mannheim as a stage to highlight our leading-edge innovations and communicate our global expansion efforts,” says Harald Hammer, Borealis vice president for engineering applications. “New grades and material solutions developed in cooperation with our partners in the automotive industry are helping reduce vehicle weight, making enhanced efficiency and sustainability all the more feasible. Our expansion in Itatiba enables us to intensify the development of pioneering, value-added applications in collaboration with customers and partners in South America.”

Vienna-based Borealis is owned 64 per cent by Abu Dhabi’s International Petroleum Investment Company (IPIC). Borealis provides services and products to customers around the world in collaboration with Borouge, a joint venture with the Abu Dhabi National Oil Company (Adnoc).
