In buildings across Australia, PCM use is state of the art (and science)

Ben Welter - Monday, March 02, 2015

An Australian magazine offers a wide-ranging look at how architects, designers and engineers are using phase change materials in the land down under. Products made by BASF, DuPont, Phase Change Energy Solutions, Tate Access Floors, GlassX and Phase Change Products can be found in high-tech concrete, wallboard, glass and cooling systems across Australia.

  • 20% CAGR projected for advanced PCMs

    Ben Welter - Wednesday, January 07, 2015

    The global market for advanced PCMs is projected to reach $1.47 billion by 2019, according to ReportsnReports.com. That's a compound annual growth rate of more than 20 percent over the next five years. The market for thermal energy storage PCMs is projected to register a CAGR of 22 percent in that period.

    "Organic PCM are projected to have the higher growth rate than inorganic PCM due to the higher prices and ease of microencapsulation for organic PCM," according to the report.

    Western Refrigeration using PCMs in coolers, freezers

    Ben Welter - Tuesday, December 16, 2014

    In countries like India, where power failures are commonplace, refrigerators and freezers need backup. Western Refrigeration and other manufacturers are incorporating phase change material in their coolers and freezers to keep food cold during outages -- and help the appliances operate more efficiently.

    Global demand for PCMs projected to hit $1.47 billion by 2019

    Ben Welter - Monday, December 15, 2014

    The global demand for advanced phase change materials is expected to reach $1.47 billion by 2019. The latest research report on the industry by Markets and Markets attributes the growth to increasing demand for advanced PCM in several areas, including thermal energy storage, building/construction, HVAC, cold chain, shipping, packaging/transportation, textiles and electronics.

    The main types of advanced PCMs are salt hydrates, paraffins and biobased compounds. "Biobased PCM is estimated to have the highest CAGR from 2014 to 2019," the report said. "Prices of biobased PCM are also likely to fall significantly during the same period."
