Key Application Areas of Silicone in Vehicle Manufacturing

Engine Compartment: Silicone Hoses for Extreme Temperatures

The engine compartment of modern vehicles is one of the most demanding environments imaginable. Temperatures exceeding 200°C, aggressive chemicals, and constant vibrations place the highest demands on all materials used. Our silicone hoses have been specially developed for these extreme conditions and offer reliable protection for critical lines and connections.

The exceptional temperature resistance from -60°C to +230°C makes our silicone hoses the first choice for high-performance applications. They serve as heat protection for sensitive components and as flexible connecting elements in complex piping systems. They retain their elasticity and sealing properties even under the most extreme conditions.

Our products have proven particularly effective in coolant lines of high-performance engines, where they function reliably even at peak temperatures. In charge air systems for turbo engines, they ensure optimal pressure resistance, while in vacuum lines and negative pressure systems, they guarantee precise sealing. They have also proven excellent as heating hoses for the vehicle interior.

Vehicle Interior: Comfort through Innovative Silicone Solutions

The interior of modern vehicles is becoming increasingly sophisticated. Comfort, haptics, and durability are paramount. Our silicone molded parts contribute significantly to this comfort. They provide pleasant cushioning, effectively dampen vibrations, and offer reliable protection against impacts.

The special properties of silicone come fully into play here. The material is skin-friendly, odorless, and retains its original properties even after years of intensive use. Silicone foam hoses offer the perfect combination of damping and durability, making them a preferred choice for premium vehicles.

Drivetrain: Tailored Solutions for Modern Mobility

The electrification of the drivetrain brings entirely new challenges. Electric and hybrid vehicles require special sealing and insulation solutions that meet both mechanical and electrical requirements. Our silicone products play a crucial role in vibration damping and protecting sensitive electrical systems.

Each molded part is developed and manufactured individually according to customer requirements. This customized approach allows us to develop optimal solutions for specific applications that meet the increasing demands of modern vehicle concepts.

Electrics and Electronics: Silicone as a Shield

The increasing electronification of vehicles makes reliable insulation and sealing solutions indispensable. Silicone protects sensitive electronic components from moisture, dust, and temperature fluctuations. As an insulation material and connection seal, it ensures the functionality of complex electronic systems throughout the vehicle’s lifespan.

Typical Applications in Practice

Cooling and Heating Systems: Efficiency through Reliability

Modern vehicles require highly efficient cooling systems that must withstand extreme temperature fluctuations. Our silicone hoses offer the necessary flexibility and temperature resistance for these demanding applications. In engine cooling systems, they ensure reliable cooling even under the most extreme conditions.

Heating circuits benefit from the excellent temperature resistance of our products, while air conditioning lines benefit from their chemical resistance to refrigerants. In hydraulic systems, they ensure precise pressure transmission and long-term tightness.

Exhaust Systems: Protection against Extreme Loads

Exhaust systems generate not only high temperatures but also strong vibrations and aggressive exhaust gases. Silicone-based mounts and dampers effectively reduce vibration transmission and protect other vehicle components from damage. Their temperature resistance makes them the ideal choice for this demanding application.

Sealing Systems: Reliability in Every Situation

From simple O-rings to complex multi-part sealing systems – our silicone products offer reliable sealing in various vehicle areas. Door seals ensure comfort and noise reduction, while window seals provide optimal weather resistance. Engine seals must withstand extreme temperatures and pressures, while electronics housing seals protect sensitive components from environmental influences.

Electrical Systems: Protection for the Future

The electrification of the automotive industry brings new challenges. Silicone-based insulation and sealing solutions play a crucial role in protecting electrical components. They prevent the ingress of moisture, insulate against electrical voltages, and ensure the long-term stability of complex electronic systems.

Especially in high-voltage systems of electric and hybrid vehicles, reliable insulation materials are indispensable. Our silicone products meet the strictest safety requirements and contribute to the safe functioning of these forward-looking technologies.

Outgassing Behavior: Critical Factor for Electronic Systems

In modern vehicles, material outgassing can lead to malfunctions of sensitive electronic components.
