For Electrical and Electronic Components
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 Advanced Polymers 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.
