At the PIAE Congress, the company will present three new polycarbonate blends, which meet the different requirements for use in car interiors. For example, the PC+ABS (acrylonitrile-butadiene-styrene) blend Bayblend® T85 XAT is anti-static and provides permanent dust-free interior paneling – in accordance with specifications of major car manufacturers. In addition, it is resistant to UV radiation and offers property improvements and cost benefits compared with the previous standard product PC+ASA (acrylonitrile-styrene-acrylate).
The property profile of Bayblend® T85 XUV features permanent light stability, excellent impact strength and low emissions of volatile organic components (VOC). On the other hand, the PC+PBT (polybutylene terephthalate) blend Makroblend® SR60 provides good mechanical properties and cost advantages, primarily in applications with high-gloss surfaces without a coating.
The current trend: hybrid speedometers
A current trend are hybrid speedometers, which bridge the gap between previous analog combination instruments and future purely digital display solutions for display instruments. According to studies, these hybrid solutions may dominate the global automotive market by 2025.
At the VDI Congress, Covestro will present a hybrid speedometer with a black-panel and fade-out effect and precision-controlled light functions. The three dimensional surface of the instrument consists of Makrofol® LM polycarbonate film from Covestro and was manufactured using high pressure forming (HPF); backlit symbols are seamlessly integrated. The film offers design freedom and allows functional integration of digital and analog elements. The housing was made of thermoplastic polyurethane (TPU) using a 3D printer.
Tailor-made battery materials
Covestro has many years of experience in developing polycarbonate materials for encapsulating batteries for laptops and other electronic devices. Lithium-ion batteries will also be the core component in future electric and hybrid vehicles. The company has developed various polycarbonate blends for these that meet the complex requirements and are also extremely impact-resistant over a wide temperature range – especially at sub-zero temperatures. They are suitable for battery modules, cell holders, crash absorbers and other products.
At the VDI Congress, for example, Covestro will present an Alta Pack battery from California’s e-bike specialist Alta Motors. It is encased in a housing made of the extremely impact-resistant PC+PBT blend Makroblend®. The company helps its customers develop new products by providing technical services, e.g. with rheological, mechanical and thermal simulations for optimizing the injection molding process.
Kickoff at "Automotive Night"
Along with the VDI, Covestro cordially invites participants of the congress to the “Automotive Night,” which takes place at the Mannheim factory the evening before the congress begins. The get-together offers a good opportunity to talk to other participants, speakers and exhibitors before the event starts.
