How to Determine Which Pentane Blowing Agent is Right for You

Pentane is a hydrocarbon solvent that’s derived from natural gas and crude oil.

It’s used as a blowing agent in polyurethane production, meaning it helps the substance “foam up” and deliver its excellent thermal resistance value. There are three types of pentane blowing agents: n-pentane, iso-pentane, and cyclopentane. They can be used separately or mixed together, depending on your need. With so many options to choose from, how do you know which pentane blowing agent is right for you? Let’s dive into the different properties of each and determine which one is right for your application.

Cyclopentane

After foaming, cyclopentane remains partially in the cells of polyurethane foam. As a cell gas, it conducts heat less effectively than air and thus offers an extremely high and lasting insulating effect.

Pure cyclopentane is mostly used in household appliances because a maximum insulating effect needs to be produced in a small space. You can also often find cyclopentane in cold storage rooms, refrigerated warehouses, and in sandwich panels.

N-Pentane and Iso-Pentane

Both N-pentane and iso-pentane have a lower insulating effect than cyclopentane. However, they have a unique advantage in that they are more stable and the individual cells are firmer and finer. This makes n-pentane and iso-pentane a common choice for residential or office building insulation. However, there is increasing pressure to meet more stringent energy efficiency requirements, which is creating a trend towards using cyclopentane instead.

When Should You Mix Pentane Blowing Agents?

Mixing pentane blowing agents is a fairly common occurrence, allowing you to benefit from different properties within each type of pentane. For example, n-pentane and iso-pentane are rarely used alone in the refrigerator industry. Additionally, the construction industry will mix n-pentane and iso-pentane for stronger, longer-lasting, and more insulating polyurethane foam.

The kind of pentane blowing agent you use will depend on your unique application. When you’re ready to compare and contrast different blowing agents, it’s best to talk to an experienced provider, like Linden Polyurethane.
