Covestro develops material solutions for "future car"
September 07, 2020 - Germany
Covestro has developed material solutions to provide aesthetics, comfort and functionality for the “car of the future” which is expected to be seen as a mobile, multifunctional living and working space in view of the new drive systems, increased connectivity and the trend towards ridesharing. The design of the car interior is all set to gain in importance.
The spotlight will be on functionality, comfort and design along with efficiency and light weight. It is to meet these requirements that Covestro and its partners have developed a premium concept with material solutions for the interior.
“In particular, a high-quality and individual design has considerable influence on consumers' buying decisions while providing car manufacturers opportunities for brand differentiation,” explained Jochen Hardt, vice president, global marketing mobility in the Polycarbonates segment at Covestro. “Here, the focus is on the design of surfaces using colours, optics and haptics, with light effects and functions. Products from Covestro open up almost unlimited possibilities.”
Plastics such as the polycarbonate Makrolon and the polycarbonate blends Bayblend and Makroblend are lightweight and robust and ensure good thermal and electrical insulation. They can be used to implement a wide range of design solutions, with glass-like surfaces, many colours and options for integrating displays, sensors and cameras.
Wafer-thin layers of natural materials such as wood and marble will play a vital role in the car interior of the future. On the surface of injection-molded components made of the polycarbonate Makrolon Ai (derived from "Automotive interior"), they are ideal for creating a feel-good ambience.
With lighting, the effects can be enhanced even further. One example is the floor in the prototype car interior concept: Here, light from a polycarbonate part shines through a wafer-thin layer of marble. This effect could also be created by coating it with a digitally printed film.
But the high transparency of polycarbonate itself can also be used to create lighting effects, for example by illuminating the background or edges. The light can be dynamic and communicative, but also atmospheric, relaxing and cozy. Covestro anticipates growing demand for increasingly personalised lighting experiences and functions.
Polycarbonate also forms the basis for continuous fibre-reinforced thermoplastic composites called Maezio. The unidirectional arrangement of the fibres lends the surface a special aesthetic effect. In addition, the seat shells made from it and a new space-saving table are very light and robust.
The use of paints and coatings in car interiors is also multifaceted. Many colours as well as optical and haptic effects are possible here. Covestro was a pioneer in the development of water-based coatings with a very low content of volatile organic compounds (VOC). In the interior concept, the waterborne floor topcoat is based on the polyurethane (PU) raw materials Bayhydrol and Bayhydur, which give it durability and individuality. The aqueous Insqin PU technology for textile coating is used in the headrests, instrument panel and seats.
Covestro is also a pioneer in the use of predominantly organic-based PU raw materials such as the coating hardeners Desmodur eco N 7300 and Bayhydur eco 701-90 and the urethane acrylate dispersion Bayhydrol eco 2877. The floor of the interior has been completely redesigned with PU materials to create a pleasant and homelike setting. Baypreg is a two-component polyurethane system that is lighter than steel, providing significant advantages. The combination of Baypreg and glass fibre mats with core materials such as paper honeycomb or foamed polycarbonate enables a significant reduction in weight while providing high mechanical strength.
The Baynat PU system provides effective sound absorption. It makes self-supporting components possible and has long been used in vehicle headliners, but it is likely to play a particularly important role in the quiet electric car of the future when it comes to absorbing the noise of other passengers and the world outside. The soft Bayfit polyurethane system is recommended for even greater damping of noise and vehicle vibrations. It is usually foamed in cavities for this purpose.
