Bumpers play a key role in a car's appearance. As consumer quality demands steadily rise, expectations regarding surface aesthetics, dimensional stability and narrow gap tolerances also increase.
Apart from the design challenges, OEMs are increasing their focus on pedestrian safety to raise their vehicles' safety performance to new levels without affecting design or functionality.
Borealis & Borouge have created a range of application-specific Daplen™ thermoplastic polyolefin compounds (TPO compounds) for automotive bumper systems that meet even the toughest aesthetic, processing and performance requirements, including:
- Good paintability and aesthetic surfaces
- Low Coefficient of Thermal Expansion (CTE)
- Narrowest gap tolerances
- Excellent impact/stiffness ratio
- Less maintenance
In addition, we work in close co-operation with the OEM / Tier 1 and offer state-of-the-art engineering support for bumper system.
To maximize its appeal to consumers, the visual appearance and exterior design of a car are crucial. A smooth, high quality Class A surface appearance is required to satisfy consumer demands.
OEMs want an optimized design that impacts the ease of production and associated costs without affecting design or functionality. Today, there is a drive towards more complex, light-weight, integrated parts with modular design and assembly of off-line painted body panels.
By offering a range of plastic materials for automotive body panels through various of applications like Fender, Outer Door Panel, Tailgate etc, Borealis & Borouge respond not only to the trend towards modular design and assembly of off-line painted body panels, but also makes a contribution to making vehicles lighter by providing an alternative to traditional steel components.
Borealis and Borouge Daple™ range for body panels offers:
- Class A-surface and excellent paint adhesion,
- High dimensional stability,
- Specified colours in narrow tolerances,
- Excellent impact/stiffness balance,
- Weight reduction,
- System cost reduction,
- Integration possibility & Improved functionality.
In addition, we work in close co-operation with the OEM / Tier 1 and offer state-of-the-art engineering support for body panels.
Various applications like front grills, side protection trims, cowl grills, wheel arch liners and covering parts like rocker panels or fender liners demand specific properties in combination with good surface appearance.
Materials used for exterior trims need to deliver on the flexibility required, often combining properties like narrow gap tolerances, superior scratch resistance and good paint adhesion.
Optimizing processability with aesthetic properties
Borealis & Borouge offer a variety of polypropylene (PP) resins which bring benefits such as:
- Excellent processability
- Outstanding paint adhesion
- Aesthetic surfaces and paint free solution
- Long-term weathering resistance
In addition, we work in close co-operation with the OEM / Tier 1 and offer state-of-the-art CAED support.
