Abstract:

Pipeline insulation is a technique that aims to reduce the heat loss and prevent the freezing of fluids in pipelines. Pipeline insulation is widely used in various industries, such as oil and gas, chemical, power, and water supply. Pipeline insulation can improve the energy efficiency, safety, and reliability of the pipeline system.

One of the main materials used for pipeline insulation is polyurethane foam (PUF), which is a type of thermosetting polymer that has excellent thermal and mechanical properties. PUF is formed by the reaction of polyol and isocyanate, which are mixed with a blowing agent that creates bubbles in the foam. The blowing agent determines the density, thermal conductivity, and environmental impact of the PUF.

Cyclopentane is a hydrocarbon that has been widely used as a blowing agent for PUF in recent years. Cyclopentane has many advantages over other blowing agents, such as low ozone depletion potential (ODP), low global warming potential (GWP), high solubility in polyol, and low cost. Cyclopentane can also enhance the flame retardancy and aging resistance of the PUF.

In this article, we will introduce the principle and process of pipeline insulation, the properties and advantages of cyclopentane as a blowing agent, and the challenges and solutions of using cyclopentane in pipeline insulation. We will also review the current status and future prospects of cyclopentane in pipeline insulation.

Abstract: Rigid polyurethane foam (RPUF) is a widely used material for insulation, construction, and packaging applications. However, RPUF has some drawbacks, such as high flammability, low thermal stability, and environmental issues. To overcome these problems, researchers have explored the use of isoamyl and cyclopentane blends as blowing agents for RPUF. Blowing agents are substances that create gas bubbles in the foam, affecting its density, thermal conductivity, and mechanical properties. Isoamyl and cyclopentane are both hydrocarbons that have low ozone depletion potential (ODP) and global warming potential (GWP), making them more eco-friendly than conventional blowing agents. Moreover, they can improve the flame retardancy, thermal stability, and mechanical strength of RPUF. This article introduces the basic concepts of RPUF and blowing agents, and reviews the recent studies on the effects of isoamyl and cyclopentane blends on the properties and performance of RPUF.
