| Ethylene/acrylic elastomer |
 |
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, and has a nominal specific gravity of 1.03. It has a mild acrylic odor. Use adequate ventilation during storage, mixing, and processing to prevent accumulation of residual vapors. Storage stability is excellent.
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. |
