Targeted thermal management is essential in inverters for electric vehicles. In addition to heat removal, customised potting compounds and gap fillers from Wevo also ensure the mechanical stability of the relevant components.
Wevo materials based on polyurethane, epoxy resin and silicone enable smart and durable components for fields such as air quality control, water treatment and waste separation. Among other things, the potting compounds and adhesives protect electrical and electronic components against environmental conditions and mechanical stresses.
One of the most important requirements for batteries in electric vehicles is the ability to mitigate thermal runaway. Formulated especially for this purpose, Wevo silicones serve as efficient thermal, mechanical and electrical barriers while at the same time offering advantages over alternative materials.
They combine high thermal conductivity with a structural bonding option: if necessary, Wevo adhesive systems are applied to the cooling system in three dimensions and pressed directly together with the battery cells. This enables improved dissipation of the high temperatures generated during the charging process.
Whether in local public transport, freight transport or agriculture, electric drives are becoming increasingly relevant. Efficient thermal management is crucial to prevent a loss of performance from these motors. To this end, Wevo has developed tailor-made products, which also facilitate short cycle times.
Whether in medical, industrial or agricultural settings – fans are one of the key components in modern ventilation systems, wherever they are put to use. In order to protect the electronics as individually required and ensure targeted thermal management for the fan motors, Wevo-Chemie has developed potting compounds based on polyurethane and epoxy resin.
Whether it’s for energy supply systems, mobility or gas and water management – smart city concepts involve the digitalisation of different sectors. Custom Wevo products provide reliable protection tailored to the specific needs of the electrical and electronic components that are crucial to realising these concepts.
Increasing use is being made of HVDC technology to transport renewable energy around the transmission grids. Among the key components that make this technology possible are transformers and insulators. By encapsulating them with tailor-made products from Wevo-Chemie, they become more environment-friendly and ensure both freedom from partial discharges as well as electrical insulation.
To ensure the suitability of electric vehicles for daily use a dependable charging infrastructure is crucial. This also entails protecting sensitive components from high operating temperatures and mechanical stresses. For this purpose, Wevo has developed custom potting compounds and adhesives.
Activity, feeding patterns, stress levels– thanks to modern technology, a variety of livestock parameters can now be monitored 24 hours a day, 7 days a week. Wevo materials reliably protect the sensitive components needed for this purpose – and extend the life of the applications.
The demands made on lighting technology are manifold. Apart from offering flexibility and adaptability to different environmental conditions, technical developments must also be taken into account. Tailor-made materials from Wevo support such developments and enable LED systems to be both reliable and durable.
The ATEX Directive lays down EU-wide safety standards for equipment and materials used in environments where there is an increased risk of explosion. Thanks to the silicone-based products from WEVO-CHEMIE GmbH, battery systems satisfy these requirements – and are additionally protected against thermal runaway.
WEVO-CHEMIE potting compounds are certified according to EU standard EN 45545-2 – and some of them fulfil the highest level of fire protection. This means they can be used on electrical and electronic components in the world of railway engineering, such as on transformers, sensors, relays and batteries.
Headlamps and rear lights are important design elements and at the same time fulfil increasingly complex functions. With its tailor-made potting compounds and adhesives, Wevo facilitates an efficient production process for complex component geometries as well as consistently reliable protection of sensitive components against environmental influences.
Supercapacitors are used in applications where large amounts of energy are delivered or required at short notice – from vehicles through consumer electronics to emergency power supplies. Potting compounds from Wevo provide greater design flexibility, more capacity and a longer service life.
Electrical and electronic components are often exposed to high temperatures. The materials used must therefore meet strict requirements. The new potting compounds from WEVO-CHEMIE GmbH combine very good temperature resistance with flame-retardant properties – and have been awarded exceptionally high UL ratings as a result.
Materials that come into contact with drinking water have to meet stringent conditions. WEVO-CHEMIE GmbH’s polyurethane potting compound WEVOPUR 2082 has received WRAS approval and may be used for the production of filters, pump housings and other components in the fields of drinking and process water management, and filtration.
A series of tests conducted by WEVO-CHEMIE GmbH in cooperation with the Fraunhofer Institute for Chemical Technology shows that Wevo products are highly resistant in the various oxidation states of the vanadium-based electrolyte frequently used in redox flow batteries. This could lead to new possibilities for the storage of renewable energies.
Forum de l'électronique, the event for innovations and electronic solutions, takes place in Paris. About 200 exhibitors present a wide range of technical and technological innovations for industry and research stakeholders. The show is highlighted by technical conferences, congresses and presentations.
