A recent Technavio report forecasts the global spray polyurethane foam market to grow at a compound annual growth rate (CAGR) of over 8% from 2018-2022. The use of alternative blowing agents is one of the major trends taking place in the global spray polyurethane foam market. Blowing agents, such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbon (HFCs), are being phased out due to their harmful effects on the environment and human health. Pentane is a low-cost blowing agent that produces low-density foams with low thermal conductivity and enhanced properties. Methyl formate and dimethoxymethane are also regarded as blowing agents for rigid foams.
A key factor contributing to the growth of the global spray polyurethane foam market is increasing construction activities, according to the report. During the forecast period, the need for spray polyurethane foam is expected to increase due to the growing demand for energy-efficient infrastructure facilities and housing with effective furnishing and flooring material. Polyurethane foam is a chemical product used in common construction applications that require filling, sealing, bonding and insulation. When compared to conventional roofing systems, spray polyurethane foam roofs are weatherproof, lightweight and durable, and require less maintenance.
