| Vamac® G is a terpolymer of ethylene, methylacrylate, and a cure site monomer cured using an amine-based vulcanization system. This gum elastomer includes a small amount of processing aid. It has excellent storage stability. Vamac® G has excellent high-temperature durability and oil resistance with service lubricants, coupled with good low-temperature flexibility. Compounds of Vamac® G are typically rated at 175°C (347°F) for heat resistance, with oil swell values around 50% in ASTM No. 3 oil. These properties of Vamac® G make it well suited for a wide range of automotive applications, including powertrain seals and gaskets, rocker cover and piston seals, oil coolant hoses, power steering hoses, turbocharger hoses, crankcase ventilating tubes, coverings for fuel and coolant hoses, O-rings, grommets and spark plug boots. Vamac® G is an excellent vibration damping material that is uniquely insensitive to temperature. Compounds of Vamac® G are suitable for use in torsional dampers and isolator pads. Vamac® G is a halogen-free polymer and does not decompose to give off corrosive gases when exposed to flame. It is used for flame-retardant, low-smoke, nonhalogen wire and cable jackets and in nonhalogen, low-smoke flooring. Vamac® G is well suited for injection, transfer and compression molding, and is easily extruded. Former DuPont product acquired by Celanese in 2022. |
