ETHYLENE ACRYLIC (AEM)

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)

Standard Compound: -40°C to +149°C

Primary Uses

O-rings, rubber seals and custom molded rubber components for:

» Automotive sealing applications

» Automotive transmissions
» Power steering seals

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

Application Disadvantages

» Not recommended for exposure to fuel, brake fluid, aromatic hydrocarbons or phosphate esters.
