Insulation is the ultimate multi-tasker in HVAC systems. No other insulation multi-tasks as well or as reliably as Aeroflex closed-cell elastomeric foam insulation for ducts, piping and other HVAC equipment.

Aeroflex’s Aerocel® brand of insulation enhances the energy performance, fire security, and acoustic properties of buildings. It also protects owners from the negative and often destructive consequences of moisture intrusion, including mold and corrosion under insulations (CUI). And thanks to its proprietary blend of EPDM, it lasts longer, even when installed outdoors.

Why non-polar EPDM elevates insulation performance

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.
