Borealis and Borouge introduce Fibremod solutions for Jaguar F-Type

News International-French

3 Apr 2014

The providers of innovative, value-creating plastics solutions, have developed important material solutions to address specific challenges faced by the global automotive industry.

At the VDI International Congress "Plastics in Automotive Engineering" in Mannheim, Germany taking place on April 2-3, Borealis highlights an innovative Fibremod solution developed for the Jaguar F-Type model in close cooperation with Dräxlmaier, the Tier One supplier. Other important product innovations in surface aesthetics will also be showcased, with focus on tiger stripe-free surfaces, moulded in colour and primerless two-layer paintability. Material solutions offered by Borealis and Borouge help automotive manufacturers achieve defect-free surfaces while at the same time capitalising on the benefits of lower production and system costs as well as reduced environmental impact, by way of overall vehicle weight reduction and optimised cycle times.

The Fibremod family of engineered short (SGF) and long glass fibre (LGF) compounds was officially launched in September 2013. Fibremod stands for both the name of a material category as well as the ability of Borealis and Borouge to transform or modify a specific grade to fit and exceed the needs and requirements of its customers. Borealis' proprietary LGF process technology makes it possible to tailor highly engineered polypropylene (PP) grades in order to meet the unique challenges of individual customer projects. In developing the instrument panel (IP) carrier for its Jaguar F-Type, Jaguar and its Tier One supplier, Dräxlmaier, sought a material solution that would deliver very high stiffness and excellent impact performance, without compromising other key requirements such as dimensional stability. What is more, it was imperative that the materials selected contributed to overall vehicle weight reduction and competitive system costs.

Working closely with the Tier One supplier, Borealis developed a dilution system based on 50% Fibremod GB601HP and 50% BE677AI, yielding a PP-LGF 30% with a well-defined performance profile for the IP carrier. This LGF-reinforced PP solution delivers the highest processing and end-use performance, while at the same time it contributes to lower weight and overall system costs. The Jaguar F-Type airbag chute is made of ready-to-use Fibremod GB303HP, a 30% LGF-reinforced PP which features excellent impact, high stiffness and optimal processing properties. The extensive R&D and technical support provided by Borealis made it possible to optimise the dilution fine-tuning process in order to fulfil specified property demands and the jointing technology of the IP carrier to the airbag chute.

Borealis and Borouge will highlight their surface aesthetics solutions for the automotive industry at the VDI, including updated grades for tiger stripe-free surfaces, moulded-in colour as well as primerless two-layer paintability solutions.

One of the solutions to be highlighted at VDI Mannheim is the upgraded thermoplastic olefin (TPO) Daplen EE250AI, used for instrument panels and other automotive applications to help achieve tiger stripe-free surfaces. Tiger stripes are flow mark issues caused by converting processes which can lead to both exterior and interior surface defects. Through extensive laboratory research and joint testing with partners, Borealis has developed a new PP matrix used in compounds which will help avoid tiger stripes within a very broad processing window.

The Daplen EF150HP grade is the ideal successor to one of the first breakthrough moulded in colour solutions for body panels, ED230HP. Moulded in colour solutions make cost reductions possible by eliminating the number of painting cycles required.

Borealis will also feature its primerless paintability systems for automotive exterior plastic applications. The company has developed and brought to market grades that boast improved and longer-lasting paint adhesion performance, optimised off-line painting cycle times, and the subsequent lessening of costs and environmental impact.
