Bumpers play a key role in a car's appearance. As consumer quality demands steadily rise, expectations regarding surface aesthetics,dimensional stability and low gap tolerences also increase.
In addition, Original Equipment Manufacturers (OEMs) are faced with cost competitiveness issues and seek ways to reduce development times and boost productivity while maintaining performance.
These manufacturers also want their vehicles to be lighter and more energy efficient to add to the allure of the vehicle on the consumer market.
Apart from the design challenges, OEMs are increasing their focus on pedestrian safety to raise their vehicles' pedestrian safety performance to new levels without affecting design or functionality.
Delivering durable solutions to complex challenges
Borealis has 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,
Very low Coefficient of Thermal Expansion (CTE),
Narrowest gap tolerances,
Excellent impact/stiffness ratio.
In addition, we work in close co-operation with the OEM and Tier 1 and can offer state-of-the-art engineering support for bumpers.

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.
Automotive manufacturers 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.
Achieving modular design and functionality
By offering a range of plastic materials for automotive body panels, Borealis responds 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' Daplen™ 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,
Improved functionality.
In addition, we work in close co-operation with the OEM and Tier 1 and can offer state-of-the-art engineering support for body panels.

Various applications like side protection trims, cowl grills, wheel arch liners and covering parts like rocker panels, body side mouldings 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.
Optimising processability with aesthetic properties
Borealis offers a variety of polypropylene (PP) resins which bring benefits such as:
excellent processability,
outstanding paint adhesion,
aesthetic surfaces,
long-term weathering resistance.
In addition, we work in close co-operation with the OEM and Tier 1 and can offer state-of-the-art CAED support.
