Reduce Weight without Compromising Performance
Weight reduction is a priority in the automotive industry, both to improve energy efficiency and reduce emissions. This also applies to under-hood components, such as vacuum pumps (EPV pump) in the brake oil circuit, which are subject to mechanical loads, high temperatures, and chemically aggressive environments.
Replacing Metal with a Thermoplastic Compound
A well-known multinational company in the sector has developed an innovative project: replacing metal in a vacuum pump housing, maintaining mechanical functionality while introducing thermal conductivity capabilities.
The component requires:
- Dimensional stability in a temperature range from -40°C to +120°C,
- Structural mechanical strength,
- High thermal conductivity to support heat dissipation in the circuit.
LATICONTHER 62 GRG/500: Meeting Technical Requirements
LATI has developed a custom
- 50% graphite → for a thermal conductivity of 15 W/mK,
- Short glass fibers → for mechanical reinforcement and dimensional stability.
Main characteristics:
| Property | Value / Advantage |
| Thermal conductivity | 15 W/mK |
| Operating temperature | -40°C to +120°C |
