In the aerospace industry, there is no room for mistakes. When you are designing parts for high-altitude flight or space travel, you are building systems that must survive the toughest environments on Earth.

Rapid temperature changes, extreme pressure shifts, and constant vibration are all part of normal flight conditions. At Sevitsil, we have found that true reliability is not just about strong metals or carbon fiber—it is about high-performance silicone components that keep systems sealed, pressurized, and protected.

Why Silicone Wins in the Air

The sky is a harsh environment. Engineers choose silicone over conventional rubber because it delivers unmatched stability under extreme conditions:

• Wide Temperature Range: Remains flexible at -60°C and maintains strength up to +250°C.
• Pressure Resistance: Maintains sealing performance despite rapid altitude and pressure changes.
• Lightweight Efficiency: Enables thinner, lighter seals that help reduce aircraft weight and fuel consumption.

Where Silicone is Used in Aircraft

1. Cockpit and Cabin Sealing

Silicone seals ensure airtight pressurization around windows, doors, and hatches, maintaining passenger safety even as the aircraft expands and contracts during flight.

2. Engine and Exhaust Protection

Silicone gaskets and sleeves withstand extreme engine heat, preventing hot air leakage and protecting sensitive electronics while absorbing heavy vibrations.

3. Avionics Protection

In avionics systems, silicone gaskets create protective barriers against moisture and dust, ensuring stable and reliable electronic performance.

4. Fuel and Fluid Management

High-grade silicone components resist aviation fuels and hydraulic fluids, maintaining leak-proof performance in complex fluid systems.

Why Quality Matters at 30,000 Feet

In aerospace, every component must meet the highest standards. At Sevitsil, we focus on delivering flight-ready silicone solutions through:

• Traceability: Full tracking from raw materials to final product ensures reliability and accountability.
• Shape Memory: Gaskets retain their form after repeated compression, maintaining sealing performance across thousands of cycles.
• Clean Manufacturing: Controlled production environments ensure contamination-free components.

Engineering for the Future

The aerospace industry is evolving toward electric aircraft and extended space missions. At Sevitsil, we are developing next-generation silicone materials with enhanced heat resistance, durability, and performance.

We don’t just supply components—we provide confidence that your systems will perform flawlessly on every flight.
