High-temperature resistance up to 200 °C continuous service, with excellent thermal stability.
Outstanding electrical insulation properties, maintaining dielectric strength across wide temperature and frequency ranges.
Low compression set (<15% after 72 h at 175 °C), ensuring long-term sealing performance in dynamic applications.
Excellent resistance to weathering, ozone, UV radiation, and aging without significant property degradation.
Good processability via compression or transfer molding, with consistent batch-to-batch reproducibility.
Automotive under-hood components including sensor housings, ignition boots, and turbocharger gaskets.
Electrical and electronic encapsulation for power modules, connectors, and high-voltage insulators.
Industrial sealing solutions for valves, pumps, and fluid handling systems exposed to thermal cycling.
Aerospace non-critical seals and vibration-damping elements requiring reliable performance in extreme environments.
