Plumbing is a broad term, especially when used in the context of commercial, industrial, and institutional applications. Fortunately, Aeroflex has the ideal closed-cell solution for insulating every component in a plumbing system, from hot water tanks to freeze protection insulation for sanitary waste piping.

Aeroflex sheet and pipe insulating systems are uniquely stable in the face of all things that wreak havoc with other plumbing insulating systems, including condensation, heat loss, corrosion under insulation, UV degradation, mechanical damage, and extreme temperatures. Plus, special formulations of the Aerocel® brand of EPDM insulations allow engineers to match the product with the special demands of each application, whether it be environmental conditions, aesthetic preferences, etc.

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.
