Advances thermal management and high quality electrical components

Advances thermal management…

Electrical and electronic applications take on a very important role in our technological and digital everyday life. The demands on electrical performance and mechanical strengths are becoming ever greater. As electronic components become smaller and smaller, entirely new challenges also arise.

In general, the number of E&E applications is steadily increasing with regard to automation and crosslinking in the automotive sector. However, the field of alternative drives holds great potential for heat-dissipating plastics, which are increasingly replacing metals. In many of these applications, the issue of heat generation and its effective dissipation is a major challenge. For example, thermally conductive plastics could be used to improve battery performance. Local overheating during charging and discharging can thus be avoided, while at the same time improving overall thermal management. The effectiveness and service life of the battery are increased. The same applies to the use of thermally conductive plastics in electric vehicle charging stations and power electronics.

Traditional air cooling of electronic components is disappearing due to the ongoing miniaturization of assemblies containing a larger number of components with high energy density. Heat sinks in conjunction with thermally conductive surfaces are often taking their place. Air, with its low thermal conductivity, can significantly impair heat transfer between the heat sink and the component. Innovative gap fillers with the thermally conductive Silatherm products can make an important contribution here.

In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous mass to resist shock and vibration and to exclude water, moisture or corrosive substances. Thermally conductive electrical potting compounds are an attractive option for temperature reduction and performance enhancement in e-mobility. In addition to chemical and moisture resistance, high heat dissipation and excellent electrical insulation are required. The Silatherm product range significantly increases the thermal conductivity as well as the mechanical properties of plastics. At the same time, the materials meet the requirement for insulation against electric current.

High-quality electrical components thanks to Silbond fused silica

In addition, electrical potting compounds in combination with metals can be subjected to severe thermal alternating stresses, a common cause of component damage. The outstanding property of fused silica is an extremely low coefficient of thermal expansion combined with excellent electrical insulation. The use of Silbond fused silica enables the production of high-quality, complex components from different materials and prevents cracking.

High-performance fillers for better performance

BU: High-performance fillers based on different minerals

As you can see, mineral fillers have long since ceased to be inexpensive "gap fillers"! They can be used to specifically modify the properties of modern polymer systems and adapt them to special requirements. Innovative acicular and platelet-shaped functional fillers, such as wollastonite, mica and kaolin, give thermoplastics, thermosets and elastomers outstanding mechanical strength and thermal properties. For all products, significantly improved homogenization can be achieved by a surface coating tailored to the customer's system. This leads to even better mechanical and thermal properties.
