Pentane blowing agents are widely used in the insulation industry. Since the performance and properties of Polyurethane (PU) and Polyisocyanurate (PIR) foams can vary considerably - depending on the isomer used - Haltermann Carless has conducted a study to take a closer look at the behaviour of blends consisting of the three isomers n-Pentane, iso-Pentane and Cyclopentane. The results of these tenary blends look promising and might offer additional benefits to the insulation industry.

Pentanes are indispensable in high-performance insulation materials. This important base material acts as a blowing agent in insulations and ensures that Polyurethane systems foam up and can thus develop their full performance. But what characterises this valuable material? What quality features should you look for and what supplier performance should you expect? The following article provides an overview.
