Electro Casting Resins

for electrical & electronic components

Electro casting resins – driving technology

Electro casting resins are key to the further development of numerous industries. The automotive, energy, automation, and household goods industries are all heavily dependent on developments in storing and transferring electricity.

One- and two-component electro casting resins from RAMPF Polymer Solutions boost components’ reliability and performance while also ensuring cost-efficiency and a long service life. They give your components (transformers, control units, inverters, motors, etc.) reliable and efficient protection against chemical substances and environmental influences such as heat, cold, and moisture.

Customers using our products based on polyurethane (RAKU® PUR), epoxy (RAKU® POX), and silicone (RAKU® SIL) include leading manufacturers in the automotive and electronics industries.

These products also boast a wide range of mechanical, thermal, and chemical properties. They ensure low thermal stresses by efficiently conducting heat away from your component.

Even in the event of extreme temperature changes, the material retains sufficient elasticity to reduce stresses occurring in the component.

Our first-rate materials are complemented by the extensive application expertise of RAMPF Production Systems, one of the world’s leading specialists for mixing and dispensing technology and automation solutions.

Material, machine, process – benefit from RAMPF’s highly competent complete service.

Our solutions for your applications

What do electric mobility, industry 4.0, AI, and autonomous driving have in common? They do not work properly without powerful electronics. And that is why the reliable and efficient protection of electrical/electronic components is so important.

Depending on the application, electro casting resins must perform optimally under the highest loads:

eMobility

The mobility concept of the future. The term electro mobility implies that there are many electric/electronic components in use. The task of electro casting resins here is to protect power electronics components against external influences. Furthermore, the use of heat-conductive pastes, so-called gap fillers, in heat management plays an increasingly important role in the field of batteries and electronics due to the increasing miniaturization of components. Consequently, RAMPF's electro casting resins based on polyurethane (RAKU® PUR), epoxy (RAKU® POX), and silicone (RAKU® SIL) make an important contribution to the success of electric mobility.

 

Automotive Electronics

The automobile has developed into a highly electrified vehicle. In order to control the multitude of electrical/electronic components, a modern passenger car contains up to 150 control units. Many of these components, such as sensors, ignition coils, and control units, are encapsulated with electro casting resins to ensure maximum performance and a long service life. Awarded the highest quality standards and listed by leading automotive manufacturers, RAMPF’s electro casting resins based on polyurethane (RAKU® PUR), epoxy (RAKU® POX), and silicone (RAKU® SIL) provide a convincing answer to the increasing technical and manufacturing requirements regarding insulation, protection, thermal conductivity, and the miniaturization of components.

Transformers

When it comes to electrical voltage, transformers are of great importance. They are used in a wide variety of industries and applications, including computers, sockets, and smart TVs, which all rely on voltage conversion. But transformers not only have to convert voltage, they also have to be thermally conductive and thermally resistant. The encapsulation of transformers with electro casting resins makes it possible to meet these versatile requirements. We know what matters – play it safe with RAMPF electro casting resins based on polyurethane (RAKU® PUR), epoxy (RAKU® POX), and silicone (RAKU® SIL).
 

 

Motors

Electric motors are the heart of vehicles, equipment, and machines. They convert electrical energy into mechanical energy and provide the right drive. Whether in industrial fans, household appliances, motor vehicles, or industrial machines: The motor is the most important component. It has to be highly efficient, reliable and durable, temperature and chemical resistant, and much more. With their versatile properties and high quality, electro casting resins from RAMPF ensure that motors runs at full speed and exhibit maximum durability. The innovative polyurethane (RAKU® PUR) and epoxy casting resins (RAKU® POX) guarantee for efficient and reliable casting.
