Vamac G is a terpolymer of ethylene, methylacrylate, and a cure site monomer. It is cured using an amine-based vulcanisation system.

This gum elastomer includes a small amount of processing aid and has a mild acrylic odor. Use adequate ventilation during storage, mixing, and processing to prevent accumulation of residual vapors. Storage stability is excellent.

Bale size is nominally: 560 x 370 x 165 mm

Major Performance Properties and Applications

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 for heat resistance, with oil swell values around 50% in IRM 903 oil. The 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 over a range of –30 °C to 160 °C. Compounds of Vamac? G are suitable for use in torsional dampers and ***lator pads.

Vamac? G is a halogen-free polymer and does not decompose to give off corrosive gasses when exposed to flame. It is used for flame-retarded, low-smoke, nonhalogen wire and cable jackets and in nonhalogen, low-smoke flooring.

Vamac? G is well suited for injection, transfer and compression moulding, and is easily extruded.

Compound and Vulcanisate Properties

Compounds of Vamac? are formulated and processed by customers to meet their own specific performance requirements. Many of the highest-performing compounds are vulcanizates of Vamac? are proprietary, and cannot be published. We have independently formulated a wide variety of Vamac? compounds for its own short- and long-term properties testing programs.

A typical compound of Vamac? G is reviewed below. Vulcanisate performance test data are given to help endusers evaluate the potential fitness of similar compounds for their own applications.
