As a driver of technological innovation, the automotive industry makes high demands of new materials and their quality. Thanks to decades of experience with high-performance compounds for functional parts and components, we are able to support you with advice in all issues of material selection. Consequently, using high-temperature-resistant, high-strength and tribologically optimized compounds, we are even able to produce components in plastic for very heavy-duty use.

Solutions from LUVOCOM®

In close collaboration with the development department, our regionally based engineers offer expert knowledge and personal advice on site – from project idea through to series production. With our more than 30 years of experience and broad range of products we make short development times possible.

High-temperature-resistant – in high demand

Through the use of high-temperature-resistant polymers and the addition of suitable reinforcing materials, plastics also exhibit high mechanical strengths at elevated temperatures. This technique even makes it easy and cost-effective to produce parts of the engine compartment and drive train subject to heavy loads. Temperatures of up to 260 °C are possible even in continuous operation. We will be delighted to advise you in detail on high-temperature-resistant solutions.

Carbon-fibre reinforced – for high-strength components

Components in a car have to be increasingly efficient. High strength with low weight is crucial here – with an eye towards weight reduction – for decreased fuel consumption. In components subject to a tribological load the fibre reinforcement must not lead to an impermissible level of wear. Carbon-fibre reinforced LUVOCOM® high-performance materials offer precisely these properties – they are additionally electrically conductive. These compounds have been used for years in a range of applications within the automotive sector. Examples of such components: engine-air management, transmissions, roof systems, steering and lighting.

With tribological optimization everything runs better

Many moving parts in a car are subject to high loads. During operation they must not wear and have to exhibit certain coefficients of friction. By adding lubricants and reinforcing materials such as PTFE, graphite, nanoadditives, carbon fibres and aramid, we significantly improve the tribological properties of thermoplastics.

Tribologically adjusted LUVOCOM® compounds have deposits of lubricant, which saves on expensive and time-consuming steps of additional surface lubrication. Lubricant-modified LUVOCOM® compounds are not only suitable for self-lubricating bearings, but also for all multifunctional applications in which good slip characteristics and low wear are important. In lubricated systems the dry-running properties of these materials come to the fore and thus increase the safety level for designer and user alike.

We support you during all phases of your project and advise you in matters ranging from design and material selection, through development and prototyping to mass production in millions.

Added to this are demands for higher tensile and impact strength – even at high temperature – and good tribological properties. LUVOCOM® compounds have been long-established in this area of practice.

  • Headlights

    Thermally conductive compounds for LED headlight housings, lubricant-modified compounds for components in the headlight adjustment mechanism.

  • Pumps

    LUVOCOM® VAP – high-performance compounds developed for vacuum pump vanes

    Vacuum pumps have been used for a long time in the brake servo units of cars. Originally multi-vane pumps were used, which were increasingly replaced by single-vane pumps with a significant improvement in efficiency.
    In the single-vane version, the material used for the vane must have substantially enhanced wear characteristics in order to maintain pump efficiency throughout its service life.

    If plastic vanes are employed, the plastic additionally has to have a high level of mechanical strength, rigidity and impact strength in order to withstand the high loads, especially during a cold start of the pump.

    LUVOCOM® 1105-VAP 10

    LUVOCOM® VAP compounds have been developed with this especially in mind and, because of the rising demands placed on pump performance and cost-effectiveness, are continuously undergoing development in close collaboration with our clients. A distinction is made in our LUVOCOM® compounds according to whether a fully plastic vane solution or an end cap solution is involved.

    In this respect we can call on a great wealth of experience and select the most suitable material for each specific application.

    During the material examination shown, we compared LUVOCOM® VAP compounds with familiar vacuum pump materials under conditions specific to the application.

Solutions for fuel management

Plastics play an important role within modern systems of fuel management. They help to make thes system lighter, safer and more effective and thus reduce fuel consumption as well. Every component in this field is subject to separate requirements. Fuel line connectors, for example, often have to be electrically conductive. Impellers for petrol pumps have to exhibit high dimensional stability. Bearing materials in this assembly should offer good wear-resistance. All materials used must have a good level of resistance to the fuels employed.
