ETHYLENE ACRYLIC (AEM)
Ethylene-acrylic (Vamac ®) is a terpolymer of ethylene, methyl acrylate, and an acid-containing monomer as a cure site. It exhibits properties similar to those of Polyacrylate, but with extended low temperature range and with enhanced mechanical properties.
Ethylene-acrylic offers a high degree of oil, ozone, UV and weather resistance.
Temperature Range (dry heat)
low
high
- 40 °F(- 40 °C)
300 °F(149 °C)
Application Advantages
» excellent vibration dampening
» excellent heat aging characteristics
» good dynamic property retention over a wide temperature range
» resistance to transmission fluids, water, glycol mixtures, and alkalies
Primary Uses
Application Disadvantages
O-rings, rubber seals and custom molded rubber components for:
» Automotive sealing applications.
» Automotive transmissions
» Power steering seals
