Automotive and aerospace engineering push materials to their limits. Components must survive intense heat, freezing cold, high pressure, and constant vibration—without compromising performance. Liquid silicone rubber (LSR) has emerged as one of the most reliable solutions, offering resilience where traditional materials often fail.
Withstanding Temperature Extremes
In a car engine bay or an aircraft engine compartment, temperatures fluctuate dramatically. LSR resists thermal degradation and retains elasticity from -50°C up to 200°C or more. This thermal stability ensures seals, gaskets, and dampers perform consistently over long service lives.
Vibration and Mechanical Stress
Both vehicles and aircraft generate significant vibration, which can loosen fasteners or degrade components. LSR’s natural damping properties absorb and dissipate vibration, protecting surrounding parts and enhancing passenger comfort.
Resistance to Fluids and Chemicals
Engines and fuel systems expose materials to oils, fuels, and cleaning solvents. LSR is inherently resistant to many of these fluids, ensuring long-term durability without swelling, cracking, or losing elasticity.
Automotive Applications
Seals and gaskets in engines, transmissions, and electronics.
Headlight components that require transparency and UV resistance.
Electric vehicle (EV) parts, including connectors and battery seals, where both temperature and electrical insulation are critical.
Aerospace Applications
Cabin seals and insulation to maintain pressure and temperature control.
Vibration-damping components in sensitive avionics.
Lightweight seals that reduce overall aircraft weight while maintaining reliability.
Meeting Safety Standards
Both industries demand materials that pass rigorous safety tests. LSR’s proven compliance with international standards helps manufacturers meet requirements faster, reducing time-to-market for new designs.
From car engines to aircraft cabins, liquid silicone moulding is setting the standard for reliability in extreme conditions. Its unique combination of thermal stability, chemical resistance, and vibration absorption ensures vehicles and aircraft remain safe, efficient, and dependable.
