Description

Vamac 123 is a high-performance ethylene acrylic elastomer (AEM) known for its excellent heat, oil, and ozone resistance. This specialty polymer is engineered to deliver superior durability and sealing performance in demanding automotive and industrial environments. It is an essential material for manufacturers of critical components such as engine seals, hoses, and vibration dampers, where long-term reliability under harsh conditions is paramount.

Application

• Automotive Sealing Systems: Primary material for O-rings, shaft seals, and gaskets in engines and transmissions.
• Coolant & Power Steering Hoses: Used in inner tubes and covers for hoses requiring long-term fluid compatibility and heat resistance.
• Vibration Control Components: Manufacture of engine mounts and other dynamic parts needing oil and heat resistance.
• Industrial Seals & Diaphragms: Critical for seals in oil and gas, chemical processing, and heavy machinery applications.
• Electrical Connector Seals: Provides environmental sealing for automotive and industrial electrical systems.
• Roll Coverings & Belts: Used in applications requiring resistance to oils, heat, and dynamic stress.
