The density of a foam layer is also important. Its composition has a large effect on its acoustic properties, as does the amount of gas and liquid it contains. The pore size of a particular foam also determines the effective attenuation and velocity. Moreover, the type of gas and surfactants that are used to stabilize the foam can be related to its attenuation and sensitivity.
The global polymethacrylimide foam market is segmented into three major regions: North America, Europe, and Asia pacific. The North American region is driven by increasing demand for lightweight and energy-efficient aircraft. In Europe, growth is anticipated primarily in the aerospace and defense application segment.
Additionally, demand for PMI foam is expected to increase in countries such as Germany, the United Kingdom,Low dielectric foam and France. The aerospace industry is another market that has a large market for polymethacrylimide foam. The aircraft industry is a major application for this material. Some of the leading aircraft models using PMI foam include the Gulfstream Aerospace G150 and Comac’s ARJ21. It is also increasingly used in the production of missile components and space vehicles.
In addition to its many applications, PMI foams have a number of benefits, including low maintenance and emissions and significant impact strength. North America accounts for the largest share of the polymethacrylimide foam market, with the United States and Canada as the largest consumers.
However, the decline in the automotive industry is expected to limit demand by the end of 2020. The coronavirus pandemic has also impacted the market and its prices. The 2nd quarter of FY2020 has seen a decrease of more than 10%. The global polymethacrylimide foam market is expected to remain low for the remainder of FY2020.
