Selecting the proper insulation for mechanical equipment in industrial facilities is challenging for the owner and mechanical engineer due to critical success factors such as wide ambient and line temperature ranges, cycling systems, expensive piping and equipment, condensation, noise & process control, personnel and fire protection, all while requiring minimal downtime.

Aerocel EPDM closed cell elastomeric foam insulation offers industrial facility owners a favorable return on investment by saving energy while protecting equipment from corrosion under insulation (CUI) when insulating pipes, pumps, tanks, vessels and spheres.

Why non-polar EPDM elevates insulation preformance

Aeroflex's Aerocel brand of insulation products are unique among other closed-cell elastomeric foams in that they are classified “non-polar.” EPDM (Ethylene Propylene Diene Monomer) is a non-polar compound and the basis for all Aerocel insulation.

Polarity is a function of the electrical charge across a molecular structure. When a material is classified as “non-polar,” it means that the electrical charges are evenly distributed across each molecule. This makes the molecules more stable, especially when exposed to water.  As a result, Aerocel insulation degrades at a slower rate than other closed-cell elastomeric brands, especially when exposed to moisture, sunlight, ozone and a wide range of temperatures.

Because Aerocel EPDM insulation is hydrophobic, meaning that it does not react with water, it is inherently microbial-resistant and lasts longer, providing owners with a more favorable product life-cycle assessment and cost than other closed-cell elastomeric foam insulations.
