Toray Develops Low-Dielectric-Loss PBT for 5G Communications, Automated Driving and Intelligent Transportation Systems Applications

Toray Industries, Inc., announced today that it has developed a high-performance polybutylene terephthalate (PBT) (see Glossary note 1) whose dielectric losses (note 2) in the high-frequency millimeter wave band are around 40% lower than those of conventional PBT without compromising dimensional stability and moldability. The new offering product should significantly enhance the performances of high-speed transmission connectors, communication modules, millimeter wave radars, and other equipment for 5G base stations and automated driving systems. The company looks to initiate full-fledged sample work to meet demand for materials used in 5G communication materials. It will develop applications for advanced driver-assistance systems (note 3) and intelligent transportation systems (note 4) for automated driving setups. Applications for PBT include automotive, electrical, and electronic parts. This reflects its outstanding balance of dimensional stability, strength, and other performance elements. It is also easy to mold and process. There has been a growing need in recent years to lower dielectric losses and thereby cut transmission losses in high-frequency components for automated driving and other applications. This has led to the adoption of polymer alloys (note 5) and fillers. There are limits to reducing dielectric losses, however, as such losses from the resin itself are large. Other issues are heat resistance and mechanical property degradation. Toray’s PBT delivers a loss tangent (note 6) of 0.006 in the ultra-wide 79 GHz millimeter wave band. Losses from that factor are around 40% below those of conventional PBT resins while retaining their basic properties. That is because the company constrained the polymer’s molecular motion in the high-frequency range by leveraging polymerization technology to attain a new structure. The new offering keeps the dielectric loss low across 5G communication frequency bands, from sub-6 GHz through high-frequency millimeter wave bands. Dielectric stability is superb in very hot and humid environments. It cuts transmission losses and enables wide-area sensing for incident waves from wide angles, which is an issue in designing high-frequency components. It has been challenging to downsize products without changing the electrical resistance of electric circuits and connectors. The low dielectric loss of Toray’s new resin makes it possible to keep electrical resistance unchanged, which should contribute to shrinking products, reducing weight, and improving performance. Toray has commercialized a range of 5G-suitable resins, and will promote its new offering for use in semiconductor devices and electronic components to support advanced communication technologies. The company will keep developing revolutionary materials that contribute to social progress in line with its commitment to innovating ideas, technologies, and products that deliver new value.

A dielectric loss is an energy loss caused by the conversion of electromagnetic wave energy into heat in a material. Advanced driver-assistance systems employ various sensors to assess surrounding conditions, inform and warn to drivers, and modify steering wheel and brake control to enhance safety for all road users. Intelligent transport systems manage information on people, roads, and automobiles to help reduce accidents, congestion, and environmental impact. Polymer alloys are performance-enhancing polymer blends. The loss tangent indicates the extent of dielectric losses. Plastics : https://www.toray.jp/plastics/en/

Rimac Nevera Storms into London with H.R. Owen

The Rimac Nevera, a next-generation 1,914hp all-electric hypercar GT that redefines automotive performance, has arrived in London courtesy of H.R. Owen. The UK’s leading luxury dealer group is the only official retailer of Rimac Automobili vehicles in the country, and one of a select global network responsible for selling the limited run of just 150 Neveras. Proudly designed, developed and built in-house at Rimac Automobili in Croatia, Nevera’s visit to H.R. Owen in London marks the first time it has been seen outside of its home country. It also represents the very first stop on Nevera’s world tour which, over the next eight months, will take in nearly 20 stops in mainland Europe, Asia, the US and beyond. Under H.R. Owen’s care, the Nevera silently roamed the capital, exploring its Ultra Low Emissions Zone under electric power, and taking in some of its most iconic sights, from the London Eye to the exclusive boutiques of Mayfair. Now, the H.R. Owen team will be hosting a series of exclusive static display and drive opportunities for potential Nevera customers, making them one of just handful of people outside of Rimac who have experienced the Nevera’s astonishing performance. Later this week, the car will head to the Goodwood Festival of Speed, where it’ll be tackling the hillclimb in the Supercar Run. Ken Choo, H.R. Owen CEO, said: “Since meeting Mate Rimac and the whole Rimac Automobili team two years ago, we have believed wholeheartedly in their vision. To finally now see the culmination of years of development, with the Nevera finally in our showroom and on the streets of London, is a very special moment. Led by the Group Chairman of Berjaya Corp Berhad, Vincent Tan, H.R. Owen has built a reputation for extraordinary attention-to-detail in customer service, just as Rimac has perfected every small detail on the Nevera. It’s the foundation for a great partnership between our brands.” There has never been a car like the Rimac Nevera, a next-generation all-electric hypercar opening up new dimensions in roadcar performance. With 1,914hp from four electric motors, Nevera can accelerate to 60mph in 1.85 seconds[1] and to 100mph in just 4.3 seconds. It maintains its eye-widening acceleration throughout a full-throttle cycle, achieving 186mph (300 km/h) from rest in 9.3 seconds. Nevera also bears a Croatian name, and one that truly reflects the prodigious performance it can unleash in the blink of an eye. A nevera is a powerful Croatian storm, charged by lightning and appearing with exceptional speed and potency. Just like the storm, the Rimac Nevera is just as adept at transforming its character in an instant – from assured and comfortable grand tourer to ultra-focused performance machine. H.R. Owen is not only the sole UK supplier of Rimac Automobili vehicles, but is also Britain’s leading luxury automotive dealer group, retailing some of the world’s most sought-after premium car brands – Bugatti, Rolls-Royce, Aston Martin, Bentley, Ferrari, Maserati, Lamborghini, BAC, Puritalia and Rimac.

Ground-Breaking Hydrogen-Powered MissionH24 Endurance Racer to Make UK Debut at the 2021 Goodwood Festival of Speed

MissionH24’s ground-breaking hydrogen-powered endurance race car – LMPH2G – will make its UK debut at this year’s Goodwood Festival of Speed. The racer will take on the world-famous hillclimb and it will be showcased on the Michelin Supercar Paddock stage every day of the four-day event. LMPH2G represents a significant technological development, backed by partners Michelin and hydrogen fuel cell maker Symbio – a joint venture between Michelin and Faurecia. The H24 has its sights set on the world's premier endurance racing competitions, including the 24 Hours of Le Mans. Its four-stack hydrogen fuel cell powers four electric motors, creating a combined output of 653hp. This power, coupled with the car's lightweight chassis and aerodynamic features, give it a top speed in excess of 185mph (300 km/h), while allowing it to maintain the durability and handling performance expected of a high-level endurance racing vehicle. Alongside the GreenGT H24, Michelin will be unveiling its revolutionary race tyre made up of 46 per cent sustainable raw materials, including recycled carbon black from end of life tyres, orange and lemon peel, sunflower oil, pine resin and recycled steel from packaging. Michelin has pledged to make all its tyres with 100 per cent sustainable materials by 2050 – and by 2030, 40 percent of all materials used in tyres across the group will be sustainable. Now Michelin will use endurance racing as a laboratory to accelerate the development of sustainable, high-performance tyres. Peyman Sabet, vice president of business development at Michelin Europe North, said: “The partnership with GreenGT H24 highlights Michelin’s drive to innovation and it is the perfect vehicle to feature Michelin’s 46 per cent sustainable tyres. Both pioneering developments honour the company’s commitment to sustainability, without compromising on performance. We are delighted to bring MissionH24 to the Goodwood Festival of Speed and really excited that fans will be able to watch it take on the hill.” In combination with batteries, hydrogen fuel cells will be used to increase range and enable the development of green long-distance and urban travel. Symbio has targeted production of 200,000 fuel cells a year by 2030. In 2018, Le Mans organiser Automobile Club de l’Ouest and electric-hydrogen specialist GreenGT announced that they would launch a hydrogen class of vehicles in 2024; an initiative collectively known as MissionH24. The Michelin Supercar Paddock will also feature dozens of the world’s fastest, rarest and highest-performance cars. TV star Vicki Butler-Henderson and legendary racer Tim Harvey will host the action, talking all things supercar on the interactive Supercar Paddock stage.
