Design and performance from a single source
Moving Towards the Mobility of Tomorrow
Demands on modern cars are increasing rapidly. The vehicle of the future should be chic and individual, as well as solid and undemanding in terms of maintenance, and also safe, efficient and environmentally friendly. However, so long as conventional materials continue to be used, we are reaching the limit in terms of how all these characteristics can be optimized. This applies both to the exterior of a vehicle as well as the interior.

With new materials from Covestro, the limits of what is technically feasible can be pushed: high-tech polymers, groundbreaking coatings and novel light functions enable a quantum leap into a new era of innovative mobility concepts that combine revolutionary design with a high standard of performance. Covestro is making great strides in this direction and works closely with scientists, universities and companies. The aim is to become even more innovative in future.
Experts predict that there will be at least 2 billion vehicles worldwide by 2050. Each of these is a good reason to rethink what materials should be used in automotive engineering.

The New Lightness of Driving

Innovative materials and processes provide new inspiration where vehicle exteriors are concerned

Progress is not a means to an end when it comes to automotive engineering, but offers car manufacturers and their customers clear benefits. Covestro uses innovative materials and innovative processes to create applications that make cars more efficient and at the same time improve their appearance.

But that’s not all: innovations in the field of vehicle exteriors also reduce the consumption of resources in production and reduce the weight of vehicles. Covestro is thus making a decisive contribution to the spread of electromobility. After all, the lighter a vehicle with electric drive is, the greater its range.

More design possibilities

Glass and metal. In automotive engineering, this combination has always been regarded as a peerless standard in the construction of windows and roofs. A high-tech solution is now calling this into question: transparent polycarbonate. The material combines the strengths of conventionally used materials – and at the same time overcomes their weaknesses.

In comparison to glass, polycarbonate has two decisive advantages. On the one hand, the high-tech plastic is only around half as heavy but retains comparable resistance. This makes the car more economical in terms of fuel consumption and thus more environmentally friendly. On the other hand, polycarbonate can be molded much more flexibly than glass and is therefore suitable for complex geometries. This gives car designers unprecedented freedom of design. This is a decisive competitive advantage because unique design is one of the most important criteria for standing out from the crowd today.

Instead of the usual structure consisting of windows, columns and roof, polycarbonate can be used to realize the entire roof area as a continuous, transparent dome. This design not only looks spectacular, but also improves the passengers’ visibility to a full 360-degree panorama. The result? Luxury thanks to new perspectives and at the same time a big boost in safety for other road users.

A new directive has recently made it possible to use polycarbonate as a material for windscreens. This is a decisive step for the automotive industry, as it paves the way for innovative all-round glazing that raises the design, efficiency and safety standards of future models to a new level. Covestro will continue to support automotive manufacturers and suppliers in the future.

Lower weight

Innovative materials make a decisive difference, and not just when it comes to windows and roofs, but also for components such as mudguards, bumpers and bonnets. Here, polyurethane foam is increasingly being used. In an accident involving pedestrians and cyclists, it not only provides particularly good cushioning in the event of a collision, but also significantly reduces the weight of a vehicle. This factor is particularly important for the development of electromobility, because the lighter an electric vehicle is, the greater its range. Covestro researchers believe it is possible to reduce the weight of body components by up to 50 percent.

Novel light functions

Innovative applications in automotive lighting technology will be introduced in the coming years. Developments by Covestro are helping to redefine car lighting with the use of holographic technology. Holographic films can be used, for example, to integrate various lighting functions into the bodywork. Due to their particularly thin properties, the films open up new possibilities for using light as a design element. The 3D effect, which is created by the backlighting of the films with LEDs and reflectors, is particularly spectacular.

Innovative polycarbonate is already standard in headlamps. The material is not only light and stable, but also allows the use of energy-saving LED technology. The reason for this is that the plastic is able to act as a lens and light guide. At the same time, it offers designers a great deal of freedom because polycarbonate allows headlamps to be individually designed and joined seamlessly to other components.

Bio-based coating hardeners

Covestro also strives for greater sustainability in automotive coatings. The company has developed a bio-based hardener that is used in the production of clear coatings. 70 percent of the hardener’s carbon content comes from renewable raw materials, which means a massive reduction in the use of fossil resources. A clear varnish based on the hardener from Covestro has recently been applied for the first time on a test body of an Audi Q2. With regard to scratch resistance, gloss and protection against the effects of weathering, the new type of paint is in no way inferior to conventional products – despite the sustainable production process.

Modern Elegance Coupled with Versatility

Modern plastic solutions fulfill a wide range of functions in vehicle interiors

Car manufacturers and car buyers also place high demands on the interior. A vehicle should not just be inviting and of high quality, but also fulfill many practical functions: high-quality surfaces, comfortable seats and the integration of the latest technology are just a few of the keywords in this respect. High-tech plastics by Covestro enable manufacturers to clearly differentiate themselves as well as install highly functional equipment.

At the same time, manufacturers and car buyers are expecting vehicles to become increasingly sustainable. Covestro also scores points in this area with particularly environmentally friendly applications and process technologies. The Covestro portfolio also includes coating hardeners, for which 70 percent of the carbon content is derived from biomass.

Versatile foam

Rigid polyurethane foams have always been one of Covestro’s key products. They are used, among other things, for the manufacture of fittings and roof linings for cars, as they are stable and at the same time flexible and malleable. For example, technical components such as displays, loudspeakers and reading lamps can be integrated into it. But the hard foam also offers further advantages: thanks to its high insulation performance, it ensures a pleasant noise level and thermal insulation in the vehicle. This has a positive effect both in winter and summer, as energy for heating and air conditioning can be saved. This is particularly important for electric cars, as it saves battery power and increases the vehicle’s range.

It is not just Covestro rigid foam that is used in vehicle interiors, but also flexible polyurethane foam – for example in car seats. When foam with different degrees of hardness is combined in one seat, comfort increases compared to earlier materials. The trend here is also towards lightweight construction: the aim is to design seats with the same consistently high level of comfort but significantly lower weight.

Varied surfaces

The interior surfaces of a car have to perform well because they have to look good, be resilient and at the same time be functional. Covestro has the necessary expertise in this area as well: varnishes and wafer-thin polycarbonate films give the surfaces in the car a pleasant feel and luxurious appearance. One example is the soft-feel lacquers, which are only a few hundredths of a millimeter thin and are used on handles, fittings and switches.

Innovative laser engraving processes also allow the combination of matte and glossy components on the same surface, such as on a steering wheel, for example. Direct-coating technology enables the surface of a component to be given a 3D effect.

Clear elegance

The wafer-thin polycarbonate films not only meet the required design aspects, but also possess particularly intelligent properties. With the black panel effect, for example, they ensure that displays are glare-free and only visible when they are actually needed. They can also be used for atmospheric, three-dimensional displays and LED light guides. This makes the cockpit of a vehicle clearer and more elegant, despite the increasing number of displays. In this way, Covestro combines design with functionality when creating the interior of a vehicle and sets new standards all round – for car manufacturers and drivers alike.

Creating the Future Together

Cooperation with universities and companies leads to groundbreaking ideas

New impetus is the key to fresh ideas. In order to maintain its own innovative strength, Covestro engineers are in close contact with scientists, universities and companies all over the world. These collaborations make it clear time and again that integrated solutions require integrated thinking. In the future, Covestro intends to further expand its dialog with external partners in order to use combined expertise to tackle the challenges the automotive industry is likely to face.

Defying extreme situations: “Sonnenwagen” project

One of Covestro’s collaborations is with RWTH Aachen University and FH Aachen. A group of students from the two universities is currently developing a solar-powered electric car for what is probably the world’s toughest solar car race, the World Solar Challenge 2017 in Australia. Covestro supports the “Sonnenwagen” project by providing materials, technical service and financial aid.

With this ambitious project, Covestro is pursuing two goals: firstly, the proof that innovative and sustainable mobility concepts are already possible and feasible today. Secondly, the promotion of young and talented people who are enthusiastic about and committed to the solar car project.

The project also serves to test the various Covestro materials under the harsh climatic conditions of Australia. The solar-powered vehicles are exposed to temperatures of up to 45 degrees Celsius, extreme UV radiation and a high amount of dust in the air. Among other things, a coating based on a Covestro hardener is being tested.

Overcoming borders: “Magic Revealed” project

The cooperation between Covestro, the renowned Swedish “Umeå Institute of Design” and the Finnish design agency “Northern Works” also shows how young professionals and industry can work together successfully. As part of the project “Magic: Revealed”, Covestro invited students from Sweden to Leverkusen. The aim of the meeting was to go beyond the previous limitations of design and material and to develop completely new ideas in terms of design and functionality that can make bold visions of the future a reality for car drivers.

Today, a distinctive design is a prerequisite for a strong brand identity in automotive engineering. Polycarbonate has the decisive qualities with which the industry can now reach new dimensions. In addition to its outstanding mechanical properties, the material offers a high degree of creative freedom and opens up completely new possibilities for the students. The project participants paid particular attention to the use of polycarbonate in novel day and night lighting applications, for creative surfaces as well as for integrated solutions. The success of the project was demonstrated among other things by the valuable inspiration and findings that were incorporated into the development of an automotive design study by Covestro.

Go ahead: holographic cooperation with Hella

Pushing the boundaries of what is technically feasible together: Covestro was able to implement this project together with lighting and electronics specialist Hella. By cooperating, the companies have developed a new design for signal lighting on vehicle displays, for which holographic technology is being used for the first time. The result is a world first: holographic lighting with 3D effects and a seamless and aerodynamic design. The project is an example of successful cooperation: designers from Hella initially designed the holograms. Covestro then placed them in a transparent halogen film laminated onto a three-millimeter thick glass plate. In the future, plastic instead of glass is to be used for series production.
