AEM Rubber - Ethylene Acrylate Rubber

AEM rubber is a mixture of ethylene polymer and methyl acrylate.

What does AEM Rubber mean?
The abbreviation AEM comes from the English language. It stands for acrylic ethylene rubber. In Polish, it means ethylene-acrylic rubber.

AEM Rubber - Properties

Ethylene-acrylic rubber is a blend of ethylene polymer and methyl acrylate with a small amount of carboxylic monomer crosslink. Its exceptional properties are due to its unique composition. However, ethylene-acrylic rubber should not be confused with polyacrylic rubber (ACM).

Ethylene-acrylic rubber boasts extremely high resistance to ozone and oxygen. It is also resistant to oils, although to a lesser extent than other rubbers in the ACM group. It is also resistant to water up to a temperature of 100 degrees Celsius, acidic and alkaline solutions, and glycols.

However, ethylene-acrylic rubber is not resistant to ketones, fuels, or brake oils. It also lacks resistance to alcohols, cooling fluids, and naphtha.

It has a heat resistance up to 150 degrees Celsius. For short periods, it is even resistant up to 175 degrees Celsius. Its flexibility varies depending on its application: from around -30 degrees Celsius to -40 degrees Celsius.

Ethylene-acrylic rubber - Application

Ethylene-acrylic elastomer-based blends have a wide range of applications. They undergo many formulation modifications for further processing. Most commonly, they are found in the automotive and chemical industries. They also find their use in the electrical engineering field. They are desired wherever resistance to both low and high temperatures, acids and bases, ozone, and weather conditions is important. They are also valued for their high electrical properties.
