There are good reasons why leading manufacturers from industries like automotive, Industry 4.0 and aerospace count on the inspiration and ambition of our global R&D team. They all appreciate the open attitude and innovative start-up mentality at Von Roll.
The results are visionary solutions that provide strong advantages for our customers in their markets.
Getting the chemistry right.
With a top team, leading-edge analytics and AI-based tools, we are already working today on the chemistry of tomorrow. Our Resins Lab is focused on three key areas: improved technical functionality, simplified industrial processability and maximum ecological compatibility.
Silicone-free up to more than 150 °C
For years, the automotive industry has been looking for alternatives to silicone resins to protect electronic controllers. Our answer: a silicone-free polybutadiene potting resin with a so far unmatched temperature resistance of over 150 °C.
Compared to silicone-based products, this resin is particularly cost-efficient and high-performance. In addition, it features high thermal conductivity, mechanical resistance and very good environmental compatibility — without the use of hazardous substances subject to labeling requirements.
Our impregnating resins — a booster for large serial productions
Our new epoxy-based Dolph’s® impregnating resin with excellent thermal, chemical and mechanical properties is especially suitable for the insulation and mechanical reinforcement of windings for highly stressed electric motors in all-electric and hybrid vehicles. Due to its high reactivity and rapid curing, it allows extremely short cycle times in the production process.
Green resins — the environment will say Thank You.
Superior performance and maximum environmental compatibility are not a contradiction to Von Roll! Our Dolph’s® brand has been pioneering the development of high-performance green resins for more than 50 years.
The journey continues: we invest a lot to permanently optimize the environmental compatibility of our entire resin portfolio. Avoiding solvents and hazardous substances does not only help the environment. It simplifies industrial applications and reduces processing costs.
Current status: The majority of our products already contains no or only very low levels of solvents and hazardous substances; some of our products are even completely label-free.
Longer range. More safety.
Further technical advances are needed for the final breakthrough of electromobility. We are making major contributions to this area: In the eDrive Laboratory of the Von Roll Institute, our experts are developing new solutions to massively increase the safety, efficiency and service cycle of motors and batteries.
Improving the electrical and thermal design remains the key here. Our customers benefit from our more than 100 years of know-how in the engineering of electrical systems and advanced composites.
E‑motors with maximum efficiency
For a noticeable extension in range, it is necessary to design not only more powerful batteries, but also more energy-efficient drives.
Our new insulation systems will enable a revolutionary new class of highly efficient, compact and extremely durable e‑motors. Combining high-level protection against partial discharge with excellent thermal conductivity, sets the stage for the 800 V drives of the future.
Batteries — solid power
The growing energy density in vehicle batteries places high demands on thermal management. Operational heat must be dissipated effectively — and in the event of thermal overload, chain reactions from cell to cell must be prevented.
Our Shield T products separate the individual cells within the vehicle battery in both electrical and thermal dimensions. They provide a highly effective barrier while keeping weight and volume to a minimum. At the same time, they are highly flexible in adapting to the size of the cells, which varies depending on the battery’s level of charge. Extremely precise and million times over.
Our composites are designed to handle mechanical and thermal stress with ease — and for long-term use. The groundwork for this is being researched in our Composites Lab.
This is where we develop, among other things, pioneering solutions for battery protection in electric vehicles, thermal protection materials for industrial ovens and presses, products for ballistic applications and certified solutions for aviation and rail transport.
Artificial intelligence to discover new solutions
Our chemical engineers have leading expertise in resin technologies — and they use advanced methods: for example, an AI based tool developed in collaboration with external scientists. The use of artificial intelligence is a very powerful gateway to new discoveries.
One example of successful AI-supported development is our EP200 NxtGen resin system for Prepres and Core Fillers. It provides the foundation for our innovative aerospace products. The expoxy resin outperforms conventional phenolic resins in terms of environmental and health protection. At the same time, it exceeds the performance of current market solutions regarding mechanical properties, anti-fire performance and simplicity of processing. In addition, the EP200 resin system features excellent shelf life at room temperature.
