​Elkem Silicones: high-quality rubber silicones for critical automotive parts

The automotive industry, which currently produces up to 80 million vehicles per year, is constantly innovating and demanding new high-performance applications, both under the hood and elsewhere in the car.  These new applications are often designed to reduce weight and fuel consumption, thereby leading to smaller and more compact engine compartments, resulting in higher temperatures and more stress to vital parts because of higher air pressure, greater water flow, more powerful fuel injection and corrosive fluids.

Traditional materials often have trouble dealing with these high temperatures and aggressive conditions. Elkem Silicones high-quality HCR (High Consistency Rubber) silicones, for their part, can withstand extreme temperatures of up to 200°C (300°C with specific additives) because of their stability, and are therefore ideal for a wide range of critical parts. Advanced silicones for automotive applications are designed to achieve the best balance between tear resistance and compression set at high temperatures. Furthermore, these advanced silicone products are easy to use in a wide range of processes, such as extrusion, calendering or injection molding, in line with customers’ industrial setups.

Advanced HCR silicones are ideal for use in a great variety of high-performance automotive parts:

  • Gaskets
  • Hoses
  • Spark plug boots
  • Wire and cable
  • Seals
  • Dampers
  • Connectors
  • Rain and distance sensors
  • Break-protection caps
  • Head lamp and sun-roof gaskets
  • Turbo-compressor valves

Elkem Silicone HCR formulations are perfectly adapted to these applications, because they offer the following features:

  • Ease of use – suitable for steam pressure, salt bath and hot air vulcanization, depending on the process deployed (calendering, extrusion, injection, etc.) and therefore versatile enough to produce different parts based on new design features
  • Heat stability, capable of resisting temperatures from -60°C to +300°C (which can be increased up to 300 °C using specific additives)
  • Reliable insulation and mechanical performance (including long-term vibration resistance) that outperforms standard organic polymers, with high heat and fire resistance, low smoke emissions and non-corrosive and non-toxic combustion gasses.

Our technical service laboratories provide advice for defining and optimizing processes at all stages for automotive parts manufacturers. Teams of specialized technicians, who have the expertise to propose the right silicones materials for specific automotive applications, provide technical support for mass production.
