High tear strength and excellent elongation for demanding dynamic sealing applications.
Outstanding resistance to compression set, ensuring long-term sealing integrity at elevated temperatures.
Excellent thermal stability across a wide service temperature range (–60 °C to +200 °C).
Good electrical insulation properties with low dielectric loss even under humid conditions.
Platinum-catalyzed addition cure system offering precise control, low shrinkage, and no by-products.
Automotive engine gaskets and turbocharger seals exposed to high thermal cycling.
Medical device components requiring biocompatibility and repeated sterilization (e.g., autoclaving).
Industrial fluid handling systems including fuel, oil, and coolant seals.
Electrical encapsulation and potting of sensors, connectors, and power modules.
Aerospace environmental seals where reliability under extreme temperature and vacuum conditions is critical.
